Answer:
Correct option is (B). Nyctalopia affects vision in the fovea centralis, resulting in impaired vision.
Explanation:
Nyctalopia which is also known as night blindness, in this condition it's difficult to see in relatively low light. It can cause by two types one is from birth, and another is injury or vitamin A deficiency which is also called as malnutrition.
It is caused by the loss of normal rod function in retina, and loss their ability to response in the light. The outer part of retina is made up of more rods compare to cones, loss of peripheral area repeatedly results in night blindness.
D is the answer I believe, I hope I helped :)
Answer:
The living world can be organized into different levels.
Levels of organization are structures in nature, usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level. Typical levels of organization that one finds in the literature include the atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere levels.
Explanation:
Yet, in spite of the ubiquity of the notion, levels of organization have received little explicit attention in biology or its philosophy. Usually they appear in the background as an implicit conceptual framework that is associated with vague intuitions. Attempts at providing general and broadly applicable definitions of levels of organization have not met wide acceptance. In recent years, several authors have put forward localized and minimalistic accounts of levels, and others have raised doubts about the usefulness of the notion as a whole.
Just helps a lot overall, especially if you are planning to go into a field related to biology. Hope this helps! :)
