The nucleus controls what happens within the cell
Carbon atoms have 4 valence electrons. That allows them to make 4 covalent bonds. That means they can make really big molecules. All the organic molecules have Carbon in them.
Metaphase. This is when the chromosomes line up in the center at the metaphase plate :) hope this helped!
There are two types of photoreceptors in the human retina, rods and cones.
Answer:
Option A
Explanation:
The genotypic frequency for tt (q²) = 36% = 36/100 = 0.36
To calculate for the allelic frequency of t which is q, we have to find the square root of q² to do this. Thus
√q² = √0.36 = 0.6 this q = 0.6
The allelic frequency p for the T allele can then be calculated using this formula p + q = 1
Where q is 0.6 thus p= 1 - 0.6 = 0.4.
This the allelic freq of T is 0.4
