Answer/Explanation:
Natural selection - over time - selects for traits that improve fitness. A butterfly with wing coloration that looks like a hungry owl would certainly be a deterrent to their natural predators, such as smaller birds. This is because the owl is the predator of the smaller birds, and their instinct is to avoid the owl.
If a mutation arose that resulting in coloration that looked like an owl, (or at least slightly menacing) this would be beneficial to the butterfly, as it would be more camouflaged from predators. This means it would be more likely to reach reproductive age and pass the mutation onto its offspring, who would also have a competitive advantage.
Over time, this would lead to a population of butterflies with coloration that looks more and more owl-like .
Answer: A. The water table will be lowered.
Explanation:
It would be called a biome, like a tundra or a desert.
Answer:
A) habitat fragmentation makes it easier for cowbird parasitism to occur
Explanation:
It is a situation where by there is transformation of a large habitat into smaller patches with smaller total area secluded from one another by a habitat different from the initial one.
Habitat fragmentation can be caused due geological processes which distort the physical environment. It is also casued by human activities which could lead to loss or extinction of certain species.
Habitat fragmentation could possibly lead to loss of habitat and biodiversity.
Answer:
The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. Passive diffusion is thus a nonselective process by which any molecule able to dissolve in the phospholipid bilayer is able to cross the plasma membrane and equilibrate between the inside and outside of the cell.
