In landscapes dominated by low-infiltration capacity, what is the first step in erosion?
Oksana_A [137]
Low infiltration capacity means that the soil cannot absorb much water per volume. The first step in erosion in a landscape dominated by low-infiltration capacity is the raindrop splash. This is where raindrops displace the soil from their original place because the soil cannot absorb adequate amounts of water.

In which of the following situations is evolution by natural selection most likely to occur?
Varvara68 [4.7K]

Answer:

b.

Explanation:

Natural Selection refers to the survivability of organisms based on different traits or genes that they have which then get passed on to their offspring. Based on this information we can say that a population of mountain gorillas in which individuals with genes for long hair survive the cold better is the situation in which natural selection is most likely to occur. This is because longer hair in this scenario is a gene that drastically affects the chance of survival for the gorillas and will most likely be passed on to their offspring.
