2) Fovea is the point of accurate vision. Give reason.
-

Fovea is a tiny pit located in the macula of the retina in the eye provides the accurate vision.

Explanation:

The Fovea is mainly used for sharp central vision, that is very essential for human activities like reading and driving.

In the middle of the retina is a small dimple called the fovea or fovea centralis. A thin layer of light receptor cell covers the inner surface of the choroid.

It produces high visual clarity in the eye that produces sharpest vision and greatest color discrimination. The sharpness is because of high concentration of cone cells in the fovea.

Fovea, the blind spot is where the optic nerve connects to the retina in the back of each eye is known as optic disk.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
