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.

Answer:
The model cannot explain why planets appear to go backward and make loops in the sky. Explanation: As an example, the observation of the planet Mars shows that there are times where it seems to be moving forward at first, then back, and then forward again
Explanation:
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
<span>The correct answer:
copper is important in the synthesis of collagen.</span>
Copper activates an enzyme called lysyl oxidase that's required for collagen maturation.Lysyl oxidase catalyzes the formation of aldehydes from lysine residues in collagen and this results in cross-linking collagen (stabilization of collagen fibrils).
