ATP is formed when energy is released during photosynthesis.b. When ADP + P becomes ATP, the amount of energy released is enough
puteri [66]

Answer:

c. ATP is comprised of a sugar, base, and three phosphate groups

Explanation:

ATP is the energy currency of cells and is formed during the phosphorylation of ADP. The process of ATP formation is endergonic and is often coupled with some exergonic process.

One molecule of ATP consists of one ribose sugar, an adenine base (a purine base) and three phosphate groups. Breakage of phosphoanhydride bond during hydrolysis of ATP into ADP and inorganic phosphate release a large amount of energy.

Identify which type of natural selection is described in each case below.
ICE Princess25 [194]

Answer:

Results in the evolution of the species: Directional selection

Results in new species: Disruptive selection

Favors traits at the two extremes: Disruptive selection

No increase in diversity: Directional selection

One extreme trait is favored: Directional selection

Diversity decreases: Stabilizing selection

Diversity increases: Disruptive selection

Explanation:

Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.

Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.

While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
