<h3>Answer:</h3>
Convection currents in the mantle
<h3>Explanation:</h3>
Our current laws of Physics recognize that heat is transferred by one of ...
- conduction
- convection
- radiation.
Radiation is a mechanism for transferring heat through space. That mechanism doesn't really apply inside the "solid" Earth. While a certain amount of heat is transferred by conduction, the rock making up the bulk of the Earth is a poor conductor of heat.
The majority of the heat is transferred by the hot rock physically moving from the center of the earth toward the surface in the process called convection.
Answer:
D) a genetic bottleneck
Explanation:
Genetic bottleneck refers to the sudden reduction in the population size due to some adverse climatic factors such as natural calamities. It changes the allele frequencies since the survivor population mostly have different allele frequencies than the original population.
In the given example, an earthquake kills 98% of the squirrels. The survivor population exhibits different allele frequencies for the gene responsible for the thickness of stripes. Therefore, it represents a genetic bottleneck.
Answer: i would say D but i'm not entirely positive
