Answer:
In about 100 years i believe
Explanation:
Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

Explanation:
base on the person opinion
I need help with this. It’s from my earth science prep guide.
The process of restoration when the mining activities stop in a particular area depends on how much affected the area is. Before the exploitation of the soil, there are nutrients that species like microorganisms, as bacteria, use to carry on their metabolic functions. As a result of these processes, there is a particular disponibility of other resources plants take through their roots to also develop their own biological functions.
Having this clear, the removal of these particular nutrients, that goes away with the extracted minerals, causes several impacts too difficult for restoration processes to reverse. This is why, almost in terms of a human lifetime, the recovery of the original conditions of that particular area wouldn't have been reached. Only with the pass of hundred or thousands of years, and with the action of microorganisms and intensively ecologic work, that area would be recovered.

Qué factores interviene en la manifestación de los genes? (pregunta de indagación)
Toma en cuenta el concepto de gen: El gen es la unidad física básica de la herencia. Los genes se transmiten de los padres a la descendencia y contienen la información necesaria para precisar sus rasgos. Es la unidad molecular de la herencia genética, pues almacena la información genética y permite transmitirla a la descendencia.
Ahora, planteamos nuestra HIPÓTESIS o respuesta probable a nuestra pregunta de indagación. Recordemos que tiene que tener las dos variables en relación de causa – efecto.
VARIABLE INDEPENDIENTE (CAUSA) VARIABLE DEPENDIENTE (EFECTO) INTERVINIENTES
En este caso, la hipótesis podría ser: los genes se manifiestan de acuerdo a mecanismos genéticos y ambientales. En este caso, las variables independientes (causas) podrían estar representadas por interacciones génicas e intergénicas tales como relación de dominancia completa o epistasis (factores genéticos) o bien cambios de temperatura (factores ambientales), los cuales inciden sobre la variable dependiente (grado de expresión génica) y cuyos efectos están representado por el fenotipo del individuo.
La hipótesis es una explicación plausible a un fenómeno observado en el mundo natural, la cual puede ser comprobada (o rechazada) mediante el uso del método científico.La variable independiente o 'causa' puede ser definida como la variable que produce un efecto sobre la variable dependiente, y que no cambia a lo largo del experimento.Por otra parte, una variable dependiente es una variable que cambia a lo largo del experimento de acuerdo a la variable independiente y que el investigador mide para determinar el efecto de la variable independiente.Aprende más sobre este tema en:

b. What are the effects of heat on egg
Depending on the temperature and length of exposure, heat can affect eggs in a number of different ways.
These are a few potential outcomes:
Cooking: Egg proteins are denatured and coagulated by heat during cooking, solidifying the egg white and yolk. When an egg is boiled, fried, or baked, this occurs.
Toughening: Eggs can become rigid, rubbery, or dry if they are overcooked or exposed to intense heat over an extended period.
Nutritional loss: Heat can make some nutrients in eggs, like vitamin B12 and folate, less absorbable or destroy them.
Spoilage: Bacteria can quickly proliferate if eggs are exposed to heat for an extended period of time at room temperature or in a warm environment, which can result in spoilage and possible foodborne illness.
Color Change: Heat can cause an egg yolk's color to change from yellow to greenish-gray or even dark green as a result of the interaction between sulfur compounds in the egg white and iron in the yolk. This is typically observed in hard-boiled or overdone eggs.
Overall, while heat is necessary for cooking eggs, it's essential to use the proper temperature and cooking time to achieve the desired texture and prevent nutrient loss or spoilage.

Biologist who study ecology know that microorganisms have an important role to play in the environment  describe the ecological role that some microorganisms have a decomposers 
Bacteria and fungi, for example, play an essential role as decomposers in the environment.
They decompose deceased organic materials such as fallen leaves, dead plants, and animal carcasses and reintroduce the nutrients into the ecosystem. This is referred to as decay.
Decomposers are essential for preserving ecosystem health and balance. Without them, dead organic matter would build up and nutrients would become locked up, rendering them inaccessible to other organisms.
Decomposers recycle nutrients such as nitrogen, phosphorus, and carbon into the soil by breaking down organic matter, making them accessible to plants and other organisms.
In addition to decomposing deceased organic matter, some microorganisms can degrade pollutants such as oil and chemicals, which can aid in the cleanup of contaminated areas. This is referred to as bioremediation.
Overall, microorganisms play an important part in preserving ecosystem health and balance by decomposing dead organic matter and recycling nutrients back into the ecosystem.

suppose that the number of bacteria in a certain population increases according to a continuous exponential growth model. a sample of bacteria selected from this population reached the size of bacteria in two hours. find the hourly growth rate parameter. note: this is a continuous exponential growth model. write your answer as a percentage. do not round any intermediate computations, and round your percentage to the nearest hundredth.
The hourly growth rate parameter is 69.31%.
The continuous exponential growth model is given by:
N(t) = N(0)e^(rt)
Where N(t) is the size of the bacteria population at time t, N(0) is the initial size of the bacteria population, r is the hourly growth rate, and e is the base of the natural logarithm.
From the given information, we know that the size of the bacteria population doubled in 2 hours, so we have:
N(2) = 2N(0)
We can substitute N(2) and N(0) in the exponential growth model to find r:
2N(0) = N(0)e^(2r)
Dividing both sides by N(0):
2 = e^(2r)
Taking the natural logarithm of both sides:
ln 2 = 2r
Finally, dividing both sides by 2:
r = ln 2/2
To express r as a percentage, we can multiply it by 100:
r (in %) = 100 * (ln 2/2)
The hourly growth rate parameter, expressed as a percentage, is approximately:
r (in %) = 69.31% (rounded to the nearest hundredth).

Which of the following helps protect biofilms from issues such as drying out and predators
a.) Extracellular polymeric substances
b.) Quorum sensing
c.) Becoming sessile
d.) Autoinducers
Extracellular polymeric substances help protect biofilms from issues such as drying out and predators. Option A
Biofilms are complex communities of microorganisms that adhere to surfaces and form a protective matrix. They can be found in various natural and artificial environments, such as riverbeds, medical devices, and plumbing systems. Biofilms provide advantages to the microorganisms within them, including protection from environmental stresses and predators.
One of the key components that helps protect biofilms is extracellular polymeric substances (EPS). EPS are complex mixtures of polysaccharides, proteins, and DNA that are secreted by microorganisms within the biofilm. These substances form a matrix that encases the cells, providing structural support and protecting the community.
EPS help biofilms resist drying out by retaining water and preventing desiccation. The polysaccharides in EPS can absorb and retain moisture, creating a hydrated environment within the biofilm even in dry conditions. This is crucial for the survival of the microorganisms within the biofilm.
Additionally, EPS serve as a barrier against predators. The matrix formed by EPS can make it difficult for predators, such as protozoa or grazing organisms, to access and consume the microorganisms within the biofilm. It acts as a physical defense mechanism, limiting the exposure of the microorganisms to predation.
While quorum sensing, becoming sessile (immobile), and autoinducers are all important mechanisms and processes associated with biofilms, they do not directly address the protection of biofilms from drying out and predators. So Option A is correct.
