What about this process must be altered to ensure the organelles remain in the keratinocytes?

Answer and explanation;

The melansomes are taken up from the extracellular space, so the process would either be receptors-mediated endocytosis or phagocytosis. Both of these processes send the cargo to the lysosome for destruction, so if the organelles are to remain in the keratinocyte, this final step must be inhibited.

Melanocytes are cells of neural crest origin. In the human epidermis, they form a close association with keratinocytes via their dendrites. Melanocytes are well known for their role in skin pigmentation, and their ability to produce and distribute melanin has been studied extensively. Keratinocytes play an important role in providing skin structure and in functioning of the immune system.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
