Answer:
The correct answer is option a.
Explanation:
When the process of hydrolysis moves towards the tip of the microtubule, it starts brisk depolymerization and shrinkage. The addition of GTP-bound tubulin to the tip of the microtubule again offers a new cap and protects the microtubule from shrinking.
The addition of a drug prevents GTP exchange on free tubulin dimers, that is, the drug, which prevents GTP exchange on free tubulin dimers will efficiently minimize the availability of the pool of GTP-bound tubulin dimers for addition to microtubule terminals. Thus, favoring microtubule disassembly or microtubule shrinkage.
Nucleotides are phosphate group sugar and a nitrogen base
Answer:
B) population
Explanation:
Acts on phenotypes on the individual level but evolution is at the population level. Microevolution is evolution at the population level

From the question, yellow is dominant to green.
So the parents are yellow (Yy) and green (yy)
Cross Yy x yy
Punnet square (I can't put lines):
Y y
y Yy yy
y Yy yy
Phenotypes:
Yy: yellow
yy: green
So you'd see 1/2 yellow and 1/2 green
The chromosomeshave coiled and become compact
