The image is formed in the retina. From there it passes to the optic nerve.
The optic nerve is inside the meninges. This makes it sort of part of the brain.
Things happen in the brain before nerves carry the information to the occipital
lobe.

Biologists believe that the focusing of the light rays entering the eye is focused by the crystalline lens.
Optometrists and Ophthalmologists believe that the cornea does about 2/3 of
the refracting in the eye.
Ophthalmologists make light focus on the retina by changing the curvature of
the cornea.
Biologists show light rays passing through the cornea undeviated when actually
the cornea is the part of the eye most responsible for focusing the incoming light.

What is a geostrophic wind? Why would you not expect to observe a geostrophic wind at the equator?
elena-14-01-66 [18.8K]

A theoretical wind known as the geostrophic wind is produced when the Coriolis effect, as well as the pressure difference forces, are balanced (PGF). It is a decent estimate for the wind reported at middle latitudes at an altitude of greater than 1 km. Given that there is no Coriolis effect near the equator, there can be no geostrophic wind.

What does "geostrophic wind" mean?

Geostrophic flow, as used in atmospheric research, is the fictitious wind that would emerge from a precise balancing act between the Coriolis effect and the pressure difference forces. The term "geostrophic equilibrium" or "geostrophic balance" refers to this situation (also known as geostrophy). Parallel to the isobars is where the geostrophic wind is pointed. In nature, this equilibrium seldom occurs perfectly. Because of these factors, the genuine wind and geostrophic wind nearly never match up.

The location of geostrophic winds:

At elevations exceeding 1000 meters (3300 feet), geostrophic wind can be found. With the use of weather balloons, the geostrophic wind velocity may be calculated. At heights up to 100 meters, the ground surface has a significant impact on winds.

mezya [45]

Options for the question are not given. They are as follows :

A.  Mate them and see what color the offspring are—that will be the dominant color

B.  Mate them and see what color the offspring are—the other will be the dominant color

C.  Mate them, and then mate their offspring to see what color the next generation is

D.  Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color

Answer:

A.  Mate them and see what color the offspring are—that will be the dominant color

Explanation:

Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.

When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.
