The answers is B trust me my dad is a doctor
The answer is Convergence of images behind the Retina
Convex lens converges light to a principal focus. The thickness of the lens determines the focal length (distance between the center of the lens and the principal focal point). Therefore, by evaluating the thickness of the convex lens, farsightedness, (an eye defect of convergence of images behind the retina) can be corrected by enabling images in the eye to form behind the retina.
Glucose and amino acids move in and out of cells via facilitated diffusion.<span />
vasodilatation causes a decrease in blood preasure so the answer is (B)
The light-independent reaction for obtaining energy (I think this is what you are talking about) occurs within the organism. This is because cellular respiration does not require light, seeing as how most humans do not need light directly (although they need the Sun for photosynthesis to occur in plants so that the plants produce Oxygen) in order to survive. Hopefully this helps!
