I believe the answer is The spindle fibers
Microtubule will form the spindle fibers that will grab the chromosome. The formation of microtubule will be start from prophase and it will have role in moving the chromosome through the metaphase and anaphase. If the substance disrupting the formation of microtubules, then spindle fibers will not be formed.
Answer:
b. Segments can become specialized on a particular function
Explanation:
Segmentation conditions virtually every aspect of the structure and functioning of animals with a consecutive body. Generally speaking, we can say that the main advantage of segmentation is that each segment can become specialized in a specific function.
One of its advantages is related to locomotion and comes, on the one hand, from the fact that the volume of celiac fluid remains constant in each compartment, acting as an antagonistic force against which muscles can act and, on the other, from the possibility of independently control each segment
. This allows the peristaltic movement (circular muscle contraction wave followed by longitudinal muscle contraction) to be localized and involve only those muscles that are strictly necessary, making the movement's energy needs considerably more profitable.
The compartmentalization of the body led to the repetition of structures, namely excretory, nervous and circulatory in each segment. This can be seen as another advantage of segmentation as it may lessen the impact of damage to the animal's body; Undamaged segments can maintain their normal functions and thus increase the likelihood that the animal will overcome the damage sustained.
Another advantage is that segmentation allows modification of certain portions of the body to perform specialized functions such as feeding, locomotion and reproduction.
Answer:
Frequency of p 
Frequency of p 
Number of individuals with homozygous dominant (AA) 
Number of individuals with heterozygous (Aa)
Number of individuals with homozygous recessive (aa) 
Explanation:
Out of 100 people, 10 have albino skin (aa)
So, the frequency of homozygous recessive individuals 
is 
Now, q will be
As per Hardy Weinberg's equation -
Substituting the value of q in above equation, we get -
Now the frequency of homozygous dominant (AA) will be
Hence, out of 100 people 
people are homozygous dominant (AA)
Like wise out of 100 people 
people are homozygous recessive (aa)
As per As per Hardy Weinberg's equation-
Substituting the values in above equation, we get -
So, out of 100 people 
people are heterozygous (Aa)
