Explanation:

Amino acids are seen in proteins as nucleotides are needed to create DNA.

Amino acids refers to organic compounds which are the building blocks of proteins with a central carbon atom known as the alpha carbon connected to an amino group (-NH2), a carboxyl group (-COOH), a Hydrogen (-H) group and a side chain (-R group) which can be alkyl or aryl depending on the specificity of the amino acids. A protein is formed by a linear chain of amino acids. This implies that they are combined in a certain order to form a linear chain called a polypeptide, which folds into a three-dimensional protein structure. Glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, tyrosine, tryptophan, methionine, cysteine, serine, threonine, asparagine, glutamine, aspartic acid, and glutamic acid are the 20 most common amino acids (EAA) found in proteins. Out of these 20 amino acids, 9 are essential amino acids (EAA), while the other 11 are non-essential amino acids (NEAA).

On the other hand, nucleotides are the building blocks of DNA. DNA is formed by a chain of nucleotides. Deoxyribonucleic Acid (DNA) is a long molecule that carries the genetic information required for the development, function, and reproduction of all living organisms, from bacteria to plants to animals. DNA is formed by two polynucleotide chains wrapped around each other in a double helix, with nucleotide subunits as the building blocks. Nucleotides are linked together by phosphodiester bonds to form a double helix structure of DNA. DNA molecules contain genetic information or instructions that determines the characteristics of living organisms for their development and functioning, and these instructions are written in the genetic code.

Amino acids are conjoined together by peptide bonds in a specific order and sequence to form a protein. DNA provides the genetic information needed to make proteins. Proteins are incorporated in various cellular functions as the likes of metabolism, structure, and signaling.

Therefore, amino acids are seen in proteins as nucleotides are needed to create DNA.

Explanation:

Before the development of electrophoresis to separate macromolecules, density gradient centrifugation was commonly used to isolate DNA.

Density gradient centrifugation is a technique that exploits the differences in density of macromolecules to separate them based on their sedimentation rates. In the context of DNA isolation, density gradient centrifugation allowed for the separation of DNA from other cellular components, such as proteins and RNA, by exploiting the differences in density between these molecules.

By subjecting a mixture containing DNA to centrifugation in a density gradient, the DNA molecules would migrate to a specific region in the gradient corresponding to their density. This allowed for the isolation of DNA from the other components present in the mixture.

Electrophoresis, which uses an electric field to separate macromolecules based on their size and charge, has since become a widely used technique for DNA separation and analysis. However, before its development, density gradient centrifugation was an important method for DNA isolation.

Answer:

Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive, or poorly timed application of pesticides, irrigation water, and fertilizer. Industrial farming practices, such as monocropping and intensive tillage, have also compromised soil health over time. ... Excessive fertilizer use can also cause a buildup of salts in soil, heavy metal contamination and accumulation of nitrate (which is a source of water pollution and also harmful to humans

Explanation:

However agriculture is both cause and victim of water pollution. It is a cause through its discharge of pollutants and sediment to surface and/or groundwater, through net loss of soil by poor agricultural practices, and through salinization and waterlogging of irrigated land.

Based on the observation of the dark brownish green color on the back of the blood agar plate after incubation, along with bacterial growth, the hemolytic activity of the organism can be inferred to be alpha-hemolytic.

Alpha-hemolysis is a type of hemolytic activity exhibited by certain bacteria where partial destruction of red blood cells occurs. It is characterized by a greenish discoloration of the agar surrounding the bacterial colonies. The green color is the result of the breakdown of hemoglobin in the red blood cells by the bacteria, leading to the release of iron-containing compounds.

In alpha-hemolysis, the bacterial colonies create a zone of incomplete hemolysis around them. This means that the red blood cells are only partially lysed, resulting in a greenish discoloration rather than complete clearing of the agar.

The dark brownish green color observed on the back of the blood agar plate is likely due to the accumulation of the breakdown products of hemoglobin produced by the alpha-hemolytic bacteria.

Therefore, based on these observations, it can be concluded that the hemolytic activity of the organism in question is alpha-hemolytic.

Ecological isolation is a pre-zygotic barrier to hybridization, as it prevents mating or fertilization between different species by separating them in their habitats or ecological niches. The correct answer to your question is (d) ecological isolation.

This separation may be due to differences in food preference, microclimate, or other factors that prevent the species from coming into contact with each other.

In contrast, hybrid infertility (a) and hybrid inviability (b) are post-zygotic barriers, as they involve obstacles that arise after the fertilization of gametes from different species. Hybrid infertility occurs when the offspring of two different species cannot produce viable gametes, while hybrid inviability refers to the inability of the hybrid offspring to develop properly or survive.

Genetic isolation (c) is a broad term that encompasses various mechanisms preventing gene flow between populations, including both pre-and post-zygotic barriers. However, it is not a specific type of reproductive isolation, so it is not the most accurate answer in this case.

What Do All Organisms Have In Common? All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Explanation:

Lamarck's theory of Inheritance of Acquired Characteristics proposed that an organism experiences modification that can be transmitted to its offspring. However, Darwin's Theory of Natural selection disproved the Lamarckian theory. Many biologists have tested this theory (Lamarckian theory) and the result is, more evidence is being demonstrated that the traits and behavior of organisms were the results of natural selection; hence, these changes are mainly controlled by genes.

Answer:

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place.

Explanation:

Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms). There are two types of self-pollination: in autogamy, pollen is transferred to the stigma of the same flower; in geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) gymnosperm. Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma. The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self-fertilization.

Explanation:

The oxygen-hemoglobin dissociation curve shows the relationship between the quantity of oxygen bound to haemoglobin and the partial pressure of oxygen in the blood.

Several physiologic factors, including pH, carbon dioxide (CO2), temperature, and 2,3-Disphosphoglycerate, are accountable for shifting the curve left or right. The impact of temperature on the curve is fairly simple. At greater temperatures, oxygen unloading is preferred, resulting in a rightward shift.

The oxygen dissociation curve is a graph that depicts the percentage saturation of oxyhemoglobins at different oxygen partial pressures. The curve depicts the oxyhaemoglobin and haemoglobin equilibrium at different partial pressures. The partial pressure of oxygen in the alveoli is very high.

Answer:

near the Equator

Explanation:

The part of the Earth that receives the most amount of solar radiation is always near the Equator. This is because the Earth itself revolves around the run in a tilted motion, since the Earth is round this makes the Equator always closest to the sun which means it will always get the most direct amount of Sun Radiation. This radiation causes more heat which ultimately causes a greater amount of water to be evaporated in this location.

Explanation:

If a disease wiped out the whole population of rats, it would lead to a disruption of the food chain, and many owl species may experience food shortages that would ultimately affect their survival.

Rats are a staple food for many owl species; hence, the extinction of rats due to disease may have disastrous consequences for the owl species.

It's fair to assume that many owl species would face food shortages if their rat population is wiped out due to disease.

In the end, the owl species may also be affected by the disease that kills the rats. A significant number of owl species may die as a result of food scarcity if the rat population is wiped out due to disease.

Owls, however, are opportunistic predators, which means they will feed on other animals if their primary prey is unavailable.

This means that the owls will have to adjust to their diet and find alternative prey items to survive.

Therefore, if a disease wiped out the whole population of rats, it would lead to a disruption of the food chain, and many owl species may experience food shortages that would ultimately affect their survival.
