Biology

Andre45 [30]3 years ago
4 0

Answer:

Volcanoes are formed at the divergent and convergent plate boundaries.  

<u>During a divergent plate motion, along the mid-oceanic ridge, seafloor spreading takes place. Here it is represented by location B. Due to this, the magma becomes extremely hot and exerts an upward pressure towards the seafloor</u><u>. </u><u>As a result of which the ocean floor slowly rises up forming sea volcanoes.</u> The eruption takes place and the lava forms and deposits on the seafloor, near and along the mid-oceanic ridge. As this region undergoes continuous spreading, so the crust comprised of these rocks slowly moves away from the ridge.

Most deer mouse populations inhabit regions with dark soils. These deer mice have dark brown fur. Populations of deer mice found
mixas84 [53]

Answer:

Tan fur helps the mice protect themselves from predators

Explanation:

The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
