Answer:
Pupil
Function: serves as site for entry of light into the eyeball.
Explanation:
The hole in the center of the iris is called pupil. The light enters the eyeball through the pupil. The pupil is circular or oval in shape and appears mostly black in color. With the help of muscular iris, the size of the pupil changes according to the intensity of incoming light.
Hence, the pigmented portion of the eyes of vertebrates (the iris) has a hole in its center called pupil to allow the light to enter the eyeball.
Answer:
They are divided on the basis of flowering and non-flowering plants I.e. Angiosperms and Gymnosperms
Explanation:
<u>The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds</u>
Explanation:
<h2>Therefore, option b is correct.</h2>
Answer:
These include the carbon oxides, hydrocarbons, and halocarbons (molecules with carbon bonded to F, Cl, Br, or I).

B)
%
Explanation:
A) Given
Frequency of individuals in the population having recessive phenotypes
%
Frequency of individuals in the population having recessive phenotypes is represented by ![q^2](https://tex.z-dn.net/?f=q%5E2)
![q^ 2 = 0.16\\q= \sqrt{0.16}\\ q = 0.4](https://tex.z-dn.net/?f=q%5E%202%20%3D%200.16%5C%5Cq%3D%20%5Csqrt%7B0.16%7D%5C%5C%20q%20%3D%200.4)
Thus frequency of recessive genes is equal to ![40%](https://tex.z-dn.net/?f=40%25)
frequency of dominant genes is equal to
![p = 1-q\\= 1-0.4\\= 0.6](https://tex.z-dn.net/?f=p%20%3D%201-q%5C%5C%3D%201-0.4%5C%5C%3D%200.6)
Now,
![p^2 + q^2+2pq = 1\\2pq = 1-0.16-0.36\\2pq = 0.48](https://tex.z-dn.net/?f=p%5E2%20%2B%20q%5E2%2B2pq%20%3D%201%5C%5C2pq%20%3D%201-0.16-0.36%5C%5C2pq%20%3D%200.48)
% of genes exist in the heterozygous condition
B.
Frequency of individuals in the population having recessive phenotypes
%
Frequency of individuals in the population having recessive phenotypes is represented by ![q^2](https://tex.z-dn.net/?f=q%5E2)
![q^ 2 = 0.01\\q= \sqrt{0.01}\\ q = 0.1](https://tex.z-dn.net/?f=q%5E%202%20%3D%200.01%5C%5Cq%3D%20%5Csqrt%7B0.01%7D%5C%5C%20q%20%3D%200.1)
Thus frequency of recessive genes is equal to ![10%](https://tex.z-dn.net/?f=10%25)
frequency of dominant genes is equal to
![p = 1-q\\= 1-0.1\\= 0.9](https://tex.z-dn.net/?f=p%20%3D%201-q%5C%5C%3D%201-0.1%5C%5C%3D%200.9)
Now,
![p^2 + q^2+2pq = 1\\2pq = 1-0.01-0.81\\2pq = 0.18](https://tex.z-dn.net/?f=p%5E2%20%2B%20q%5E2%2B2pq%20%3D%201%5C%5C2pq%20%3D%201-0.01-0.81%5C%5C2pq%20%3D%200.18)
