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.
The electron transport chain is part of the overall processes of cellular respiration and photosynthesis. The solution is A.
HEY DEAR..
1》 All stars die, and eventually — in about 5 billion years — our sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.
so options B is the correct answer.
2》protostar is the answer...
hope its helpfull
Option C
Humid subtropical climatic zone would these trees be found
<u>Explanation:</u>
The general trees seen in Humid Subtropical areas are largely evergreen trees, shrubs, and ferns. These are no mighty conifer trees similar to pine and spruce. Largest of these evergreens are more refined. The purpose many plants hereabouts are evergreens is because of the large months of warmness and steady rain.
These shrubs have accommodated to the natural climate circumstances. Numerous broad-leaf evergreens such as palm trees and ferns are seen hither. Douglas-fir-tanoak forest usually termed "mixed evergreen forest". A rich understory of herbs, shrubs, ferns, and fungi is discovered beneath the towering redwood and other conifers
