This spider camouflages with its environment so it is less likely to be detected by predators.
Bioprospecting is the search for plant and animal species from which medicinal drugs and other commercially valuable compounds can be obtained.
Based on this I think it could be B.
Hope this helps.
Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically. The meridians are equally spaced parallel vertical lines, and the parallels of latitude are parallel horizontal straight lines that are spaced farther and farther apart as their distance from the Equator increases. This projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps, however, because the scale is distorted; areas farther away from the Equator appear disproportionately large. On a Mercator projection, for example, the landmass of Greenland appears to be greater than that of the continent of South America; in actual area, Greenland is smaller than the Arabian Peninsula.
The fourth one that looks like an M. This is because it describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.
The answer is D. Because the bird has to be noticed and the brighter the feathers the more likely the chance to be noticed.
