In a species of grasshoppers, they can either have green or brown coloring. The environment that they live in usually receives l
ots of rain and all the plants are nice and green. However, a scientist has noticed that there ecosystem is going through a drought. Which of the following is true about the grasshopper population?A.Originally there were a higher number of brown grasshoppers, but due to the drought there are more green grasshoppers.B.The number of green and brown grasshoppers is the same in the ecosystem.C.Originally there were a higher number of green grasshoppers, but due to the drought there are more brown grasshoppers.
C. Originally there were a higher number of green grasshoppers, but due to the drought there are more brown grasshoppers.
Explanation:
Camouflage is a survival strategy widely used by living beings in nature. An example of this strategy can be seen in the question above. This is because the question shows that in nature there are green and brown locusts and the prevalence of these corres occurs in relation to camouflage with the environment in which the locusts live.
When grasshoppers live in an environment with a large number of green plants, the population of green grasshoppers is greater than the population of brown grasshoppers. That's because green locusts can camouflage themselves in the wild and their natural predators can't easily see it. However, in this environment brown locusts cannot camouflage themselves and become easy prey for predators. The opposite happens in an environment with dry and brown trees.
In general, negative selection eliminates from the population very harmful changes to proteins that kill or stop reproduction. ... The authors also found a correlation between genes predicted to be under negative selection and genes implicated in certain hereditary diseases
The correct solution for this is explained the first option. Since water has an equivalent amount or number of H ions and OH ions, pure water itself is not slightly acidic nor basic. This equality of ions, causes the pH of water to be around the mid point of the pH scale which goes from 0 - 14, and thus is 7. This is a neutral pH.
