Bees can see colors we cannot see, and they can detect minute amounts of chemicals we cannot sense. unlike many insects, bees cannot hear very well. a biologist would probably give which of the following as the ultimate explanation for their poor hearing? a-if a bee could hear, its highly programmed brain would be overwhelmed with information.
b-this is an example of altruism.
c-bees are too small to have functional ears.
d-if bees could hear, the noise of the hive would be overstimulating.
e-hearing may not contribute much to a bee's reproductive success.

The correct answer is “E”. Hearing may not contribute much to a bee's reproductive success.

Explanation:

A biologist would say that the "E" statement is correct. Those capacities that contribute more to reproductive success and survival are natural selected. Bees are pollinators that can fly long distances looking for flowers. They can see ultraviolet colors. An improved vision can help bees to find flowers while they are flying, and chemicals detection is important to communicate between them (as they are social insects) and to find flowers too.

The characteristics of bees that we can presently see, are those that were selected trough time, generation after generation and allow bees to survive until today.

About the other statements: Statement “B” is incorrect. Altruism is a behavior where an individual is exposed to some risk in benefit of the other individuals of the group. For example, when a parrot makes noises to alert the rest of the flock that there is a predator. This parrot will be more exposed than the others, but at the same time is saving their group. This behavior has nothing to do with bee’s hearing.

“C” statement is false too because small insects can have functional ears. Many insects that are also small (like crickets) have a good hearing capacity. "A" and "D" are similar. In the hypothetical situation in which bees with better hearing have greater possibilities of surviving and reproducing, probably their brain would process the information correctly.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
