What does the plant start with and what does it end with? what is the source of energy that powers this change?.
Answers
Plants starts with CO2 and ends up with glyceraldehyde-3-phosphate. It uses ATP and NADPH from the light dependent reaction as source of energy
Photosynthesis involves ranges: mild-dependent and mild-independent reactions.
• for the duration of mild-dependent reactions, oxygen is released, while ATP and NADPH are produced. each of them are used for the duration of light-independent reactions.
• light-independent response is known as the Calvin cycle, and it takes location within the stroma.
• during the Calvin cycle, sugars or carbohydrates are synthesized.
• when carbón dioxide, CO₂, enters the leaves through stomas, it diffuses to the chloroplast stroma.
• Carbon atoms fixate, meaning that they include into natural molecules. those molecules are used to produce 3-C sugars.
• The complete system is impulsed by means of ATP and NADPH coming from light-established reactions.
Stroma
1. at some point of the carbon fixation segment, a CO₂ molecule combinate with a ribulose-1,five-bisphosphate (five-C molecule) to shape 6-C molecules, in an effort to divide into three-phosphoglycerate molecules, 3-PGA (three-C molecules).
CO₂ + ribulose-1,five-bisphosphate ⟶ 6-C molecule ⟶ 2 3-PGA
2. at some stage in the discount segment, ATP and NADPH are used to produce the sugar molecule glyceraldehyde-three-phosphate (G3P) from 3-PGA molecules.
NADPH donates its electrons to turn 3-PGA into glyceraldehyde three-phosphate, G3P.
3-PGA + ATP + NADPH ⟶ G3P + ADP + NADP⁺
3. throughout the regeneration section,
a few glyceraldehyde 3-phosphate molecules leave the cycle and go to the cytosol to form glucose.
different G3P get recycled to regenérate the RuBP acceptor. This last reaction needs ATP and a chain of different reactions.
whilst 3 CO₂ enters the cycle, 6 G3P are produced. one in every of them leaves the cycle, and the ultimate five are recycled and generate three RuBP.
Cytosol:
as soon as within the cytosol, glyceraldehyde three-phosphate molecules are used to shape glucose and fructose.
those molecules are the monosaccharides that form sucrose.
once sucrose is shaped, it is transported from the photosynthetic tissues to extraordinary elements of the plant with the aid of the phloem.

what stimulates the liver to breakdown glycogen to glucose in athletes
Answers
The breakdown of glycogen to glucose in the liver of athletes is stimulated by glucagon and adrenaline.
When blood glucose levels begin to drop, the pancreas releases glucagon, which signals the liver to convert stored glycogen into glucose and release it into the bloodstream. This process helps to maintain stable blood glucose levels during exercise and prevent hypoglycemia (low blood sugar).
Additionally, the hormone adrenaline (also known as epinephrine) can also stimulate the breakdown of glycogen in the liver during exercise. Adrenaline is released in response to physical or emotional stress and works to increase blood glucose levels by stimulating the breakdown of glycogen in the liver.
In summary, the hormones glucagon and adrenaline both play a role in stimulating the breakdown of glycogen to glucose in the liver of athletes during exercise.

In athletes, the hormone glucagon stimulates the liver to breakdown glycogen into glucose. This process is called glycogenolysis.
Glycogen is a stored form of glucose in the liver and muscle tissue. When an athlete is exercising and needs an extra boost of energy, the hormone glucagon is released into the bloodstream. This hormone travels to the liver and stimulates the breakdown of glycogen into glucose. The glucose is then released into the bloodstream, providing the athlete with a quick source of energy.
In addition to glucagon, other hormones such as epinephrine (adrenaline) and cortisol can also stimulate the breakdown of glycogen in the liver. These hormones are typically released in response to stress or intense physical activity and help to provide the body with the energy it needs to cope with these situations.
In conclusion, the hormone glucagon is responsible for stimulating the liver to breakdown glycogen into glucose in athletes. This process helps to provide the athlete with a quick source of energy during physical activity.

The high temperature on the drill bit by the bit biting into rock was reduced by pumping through the bit.
Answers
The answers to the given questions are as follows:
All oil wells are drilled with the tool called a "drill bit."The rock particles created by the drill bit are removed by the "drilling mud" or "drilling fluid."The term "spud in" refers to the initial drilling of a well. The casing is inserted into the hole to keep the well walls from caving in.To reduce the high temperature on the drill bit caused by the bit biting into the rock, a process called "cooling" is employed.The procedure used to build a well and bore tubes through the Earth's surface is known as oil drilling. The tube is attached to a pump, which forcibly removes the petroleum from underground.
Because oil and natural gas are found far below the earth's surface, drilling is a difficult procedure. To access fossil fuel resources, a hole must be drilled through the crust of the planet. After that, the oil must be safely pumped out of the oil well.
Steps of Oil Drilling:
The first step in oil drilling is to drill a hole through the crust of the earth. It requires a drill string and a long bit. A "drill bit" is the instrument used in oil wells to bite into the rock and gradually deepen the hole.A tiny diameter steel pipe is placed after drilling a hole, and the spaces surrounding it are filled with cement. This helps to keep the steel casing stable.In order to lubricate the spinning bit and clear the path of the shattered rocks, the drillers fill the hole with a mixture of solids, liquids, and chemicals, sometimes referred to as "mud," throughout the drilling operation. As the drill bit goes further, more pipes must be added to the drill string. To prevent the pipe connections from separating in the well, screws must be used.Learn more about Oil Drilling from the given link:

Beyond their role in energy transfer, what other benefit do microorganisms that act as producers provide for ecosystems?
How are microorganisms involved in the movement of nitrogen from the atmosphere to the bodies of other organisms? Why can’t other organisms just get nitrogen from the air?
What is the benefit of using marine microorganisms such as Dumaliella tertiolecta to produce biofuels instead of using plants?
Answers
Answer:
The microorganisms present metabolic wastes that serve as the primary source of food for other living things.
Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.
This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.
Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.
Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.
The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.
Explanation:
By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.

Predict the effect of the changes in one population on the populations in the ecosystem.
Answers
The effect of changes in one population on the populations in an ecosystem can vary depending on the specific situation. However, there are some general patterns that can be observed.
What is ecosystem ?
An ecosystem is a community of living organisms and the non-living components of their environment with which they interact. It includes all of the living things in a particular area, such as plants, animals, and microorganisms, as well as the physical and chemical components of their environment, such as water, air, soil, and sunlight.
Ecosystems can be of different sizes, ranging from small microhabitats to entire biomes like a forest, desert or a marine ecosystem. Each ecosystem has its unique set of physical and biological characteristics that shape the interactions among the living and non-living components. The different species in an ecosystem are interdependent and rely on each other for survival and reproduction.
For example, if a population of predators were to increase in size, this could lead to a decrease in the population of their prey. This, in turn, could cause a decrease in the population of organisms that rely on the prey as a food source, potentially leading to a cascade effect throughout the food web.
Conversely, if a population of prey were to increase, this could lead to an increase in the population of their predators. This could also have ripple effects throughout the ecosystem, as the increase in predators could lead to a decrease in the population of their own prey or an increase in competition for resources.
Changes in one population can also have indirect effects on other populations in the ecosystem. For example, if a population of plants were to decline due to environmental factors, this could affect the populations of animals that rely on those plants for food or habitat.
It is important to note that the relationships between populations in an ecosystem are complex and dynamic. While it is possible to make predictions about the effects of changes in one population, the actual outcomes will depend on a variety of factors, including the specific organisms involved, the nature of the environmental changes, and the interactions between different populations in the ecosystem.

6. La problemática se basa en un mal uso de los recursos hídricos, la falta de riego en los cultivos.
8. Si, porque como se mencionó anteriormente, un uso indiscriminado de químicos daña al medio ambiente.
Explanation:
La agricultura consiste en la práctica de cultivar plantas y criar ganado. Dicha técnica fue clave para el desarrollo de la civilización humana mediante la cual la cría de especies domesticadas y recolección de cultivos creó alimentos que permitieron a la gente vivir en ciudades. En el siglo XX, la agricultura industrial basada en el monocultivo a gran escala llegó a dominar la producción agrícola. En la agronomía moderna, el fitomejoramiento, el uso de los productos agroquímicos como los pesticidas y fertilizantes, y los desarrollos tecnológicos han aumentado considerablemente el rendimiento de las cosechas, al tiempo que han provocado daños ecológicos y medioambientales generalizados. Las prácticas modernas de cría de animales han aumentado la producción de carne, pero han suscitado preocupación por el bienestar de los animales y los daños medioambientales. Los problemas medioambientales incluyen la contribución al calentamiento global, el agotamiento de los acuíferos, la deforestación, la resistencia a los antibióticos y el uso de hormonas de crecimiento en la producción industrial de carne. Ejemplos de esta degradación del medio ambiente incluyen a la pérdida de biodiversidad, la desertificación, la degradación del suelo y el calentamiento global, que a su vez provocan la disminución del rendimiento de las cosechas.
2. Si, porque de otra manera se producirían daños el medioambiente, deforestación, y degradación del suelo, el cual es un recurso no renovable. El uso sostenible del suelo permite conservarlo como recurso a largo plazo sin que se produzca su deterioramiento. Al no hacer uso sostenible del suelo, se pone el peligro la agricultura y a su vez la producción de alimentos. Hay que considerar que el suelo es un componente y recurso importante, un reservorio de gran parte de la biodiversidad del planeta. La vida de la flora y fauna depende del buen estado del suelo y nos resulta útil para la obtención de materia prima, siendo el área productiva del mismo limitada y bajo amenaza por los usos intensivos necesarios para satisfacer las demandas actuales. La gestión sostenible de los recursos del suelo contribuye eficazmente a prevenir el cambio climático.
3. Algunos ejemplos:
Rotación de cultivos: Consiste en la siembra sucesiva de distintos cultivos en un mismo terreno, a diferencia del monocultivo que se basa en la siembra repetida en el mismo campo. La rotación sirve para reducir la incidencia de plagas ya que se altera el ciclo de vida de los mismos, para controlar malas hierbas, para una distribución mas adecuada de nutrientes, etc.Mulching: Consiste en un método de corte en el cual la máquina cortacésped corta, se tritura, y se deja caer al suelo para que sirva como abono natural. Abonos orgánicos o naturales: Por ejemplo, estiércoles, compostas o residuos de cultivos. Permiten recuperar materia orgánica para la fijación de carbono, aumentan la actividad microbiana, favorece retención y uso de nutrientes y mejora la absorción de agua.Asociaciones de cultivos: Consiste en la siembra de dos o más especies próximas entre sí para que puedan beneficiarse la una de la otra.
4. Si, porque no dañan el suelo, no se utilizan compuestos artificiales o contaminantes y permite un crecimiento de la vegetación de forma mas natural, sin agotar sus recursos.
6. La problemática se basa en un mal uso de los recursos hídricos, la falta de riego en los cultivos. El riego consiste en brindarle agua a los cultivos para satisfacer sus necesidades hídricas que no fueron cubiertos mediante las lluvias, entonces es necesario capacitar a los agricultores para el correcto mantenimiento de los cultivos en cuanto a la proporción de agua que se les debe brindar.
8. Si, porque como se mencionó anteriormente, un uso indiscriminado de químicos daña al medio ambiente. Como así también disminuye la calidad de la fruta, afectando su sabor y sus nutrientes.
La mosca de la fruta es un insecto que produce un daño al picar el fruto, así las hembras realizan la ovoposición generando una vía de entrada de hongos y bacterias que descomponen la pulpa de la fruta. Esto hace que se produzca una maduración precoz y caída del fruto, y la consiguiente pérdida de cosecha. Es necesario controlar esto pero de manera responsable.

if p is the frequency of allele a, which parts of the hardy-weinberg equation correspond to the frequency of individuals that have at least one a allele?
Answers
The parts of the Hardy-Weinberg equation which correspond to the frequency of individuals that have at least one a allele is the expression (p + q), where p is the frequency of allele a.
An allele is defined as different variations of a gene that exist at the same locus. Gene is referred to as the hereditary unit that determines an individual's physical and genetic features. Therefore, the combination of alleles in an individual's genome plays a crucial role in determining his/her traits.
The Hardy-Weinberg equation is a mathematical equation that calculates the predicted allele frequency distribution in a population. It depends on the principle of genetic equilibrium, which implies the equilibrium between the allele frequency and the genotype frequency within a population. It states that if a population's breeding is random, allele frequencies in a population will remain constant over time from one generation to the next as long as certain conditions are met. These conditions are: there is no mutation, migration, genetic drift or natural selection besides the population being large enough to prevent random sampling error and the population is randomly mating.
Based on the given problem, the frequency of allele a is given as p. In order to calculate the frequency of individuals that have at least one a allele, we can use the following expressions from the Hardy-Weinberg equation: p² + 2pq + q² = 1 [where p² is the frequency of homozygous dominant genotype (AA), pq is the frequency of heterozygous genotypegenotype (Aa), and q² is the frequency of homozygous recessive genotype (aa)] and p + q = 1 (where p is the frequency of the dominant allele and q is the frequency of the recessive allele).
If p is the frequency of allele a, then q is the frequency of allele A. Therefore, the frequency of individuals who have at least one a allele correspond to the expression (p + q) in the Hardy-Weinberg equation.

What is reproductive isolation?Why is it necessary for speciation to occur? Explain one way reproductive isolation might occur.
Answers
Reproductive isolation is a process in which individuals in a population are prevented from reproducing. This isolation can occur in several ways, such as a physical barrier that separated these species into two groups that will reproduce with each other and generate a new species.
Why is it necessary for speciation to occur?Speciation is an essential evolutionary process for the creation of new species. It is worth remembering that from reproductive isolation, the individuals of a population have been differentiating and evolving and in the end, there will be a different species from the initial one. Therefore, speciation is necessary for the emergence of new species.
Explain one way reproductive isolation might occur.Reproductive isolation may occur due to a geographic barrier. In this case, a population is separated by a geographic barrier such as a river, a canyon, or a mountain, thus generating subpopulations that will begin to evolve and adapt in different ways. In the end, we will have different subpopulations, but in the beginning, they were part of the same population.
