Answer:
A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.
B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.
C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.
Note - hope this is accurate :)
No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP<span>). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called </span>aerobic respiration<span> and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

Answer:
The demand for normal goods rises with consumer income.
The results of the di-hybrid cross of pea plants with round and yellow seeds was the evidence that Mendel fond that supported his law of independent assortment.
<u>Explanation:</u>
Law of independent assortment states that the alleles of two different genes are inherited independent of each other. The law of independent assortment was formulated by Gregor Mendel . Cross of a pea plant with yellow and round seeds with a pea plant having green and wrinkled seeds gave evidence of the law of independent assortment.
When it comes to seed color yellow color is dominant to green. When it comes to seed shape round seed is dominant to wrinkled seed. Let the letter R represent round seed and R represent wrinkled seed. The letter Y represent yellow seed and letter y represent green seed.
The genotype of pea plant with round and yellow seed is RRYY and the genotype of round and wrinkled is rryy. The cross between round yellow and wrinkled green can be represented as follows
Gametes RY ry
F1 generation RrYy RrYy RrYy RrYy
All the plants of the F1 generation have round and yellow seeds.
The F1 generation plants are then bred together
RRYY RrYY RRYy RrYy RrYY rrYY RrYy rrYy RRYy RrYy RRyy Rryy RYy rrYy Rryy rryy
r
Are the progenies with phenotypes like round yellow, round green, wrinkled yellow and wrinkled green.
The combination of the characters of roundness and color is observed in the F2 generation proves that the characters of round and yellow as well as wrinkled and green doesn’t appear strictly in combination. This means that they are independently assorted which proves the law of independent assortment.
