GAMETES is made up of the male and the female sex cells.
The female sex cell is called the ovum while the male sex cell is called sperm. When these two sex cells come together during fertilization they form the gamete, which is made up of diploid number of chromosomes. Gametes are normally formed through meiosis, during the cell division, the germ cell undergo two fission, which results in four gametes,
Answer:
Long beaks of medium ground finches allows them to opt for alternate sources of food in times of extremities while this is not the case with the cactus finches.
Explanation:
The medium ground finches have larger beaks and thus apart from small seeds they can also break open the large seed. In case if the small seeds get scarce, a medium ground finch can still survive by taking advantage of feeding on alternate source of food but small beaked birds such as cactus finches shall die out of starvation.
This adaptation of medium ground finches gives it a survival advantage over the cactus finches
Deforestation is one major concern with harvesting wood. There are also all types of organisms that lose their habitats.
High rates of
volcanism, earthquakes, and mountain building are the sites of subduction
zones. They occur in convergent boundaries found in tectonic plates of both
oceanic and continental crusts. Subduction zones occur when one tectonic plate
moves under another tectonic plate, sinking into the mantle as the plates
converge again.

Regions that are
within subduction zones experience an average rate of convergence of 2-8
centimeters per year. They are subject to many earthquakes because of the
collisions that occur within the tectonic plates. </span>
