Answer:

Microtubules have shapes like a spindle and are arranged to form centrosome and a cluster of such microtubules form centriole.

Explanation:

Microtubules are seen in eukaryotic cells to give shape and structure to the cells and they form part of the cytoskeleton. They are known to grow long and are dynamic. Centrosomes are known to be main microtubule that are found in animal cells. They are organelles that are made from the arrangement of clusters of microtubules. The centrioles are organized microtubules that actually help to serve as skeletal system of the cell. These centrioles  help to determine the locations of the nucleus.

In chickens, having feathers on legs is dominant to having featherless legs. In a population of 200 chickens, 128 have featherle
Neporo4naja [7]

Answer:

64

Explanation:

Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation

p² + 2pq + q²

where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,

F of homozygous ( featherless legs) = q²

F of heterogyous ( carrier of featherless allele) = 2pq

F (q²) = 128/200 = 0.64

q = √0.64 = 0.8

and p + q = 1

p = 1 - 0.8 = 0.2

2pq = 2 × 0.2 × 0.8 = 0.32

number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
