One of the descriptions below is from the perspective of anatomical study, the rest are from a physiological perspective. Select the description below that comes from an anatomical perspective

The innermost lining of the lungs is composed primarily of thin tissue cakes simple squamous epithelium.

Explanation:

the correct one is A

Explanation:

The focal length of a lens is given

          1 / f = (n-1) (1 /R₁ - 1 /R₂)

where n is the refractive index of the lens and R₁ and R₂ the radii of curvature of the two surfaces.

In our case they indicate that the shape of the lens has not changed, therefore the radii R₁ and R₂ remain constant.

Therefore, the only way to change the focal length is to change the refractive index and as we see the two quantities are inverse, that is, to decrease the focal length we must increase the refractive index

When examining the answers the correct one is A
