Answer:

Microvilli is very common in these cells. They increase the absorption area.

Explanation:

Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.

The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. <u>Their principal function is to absorb</u>. The microvilli of the intestinal epithelium are very uniform in size and distribution.

Which steps are part of the seafloor spreading process? Check all that apply. A crack forms in oceanic crust. Volcanoes erupt un
Alex73 [517]

The answer is;

A crack forms in oceanic crust.

Volcanoes erupt under the ocean.

Molten rock rises up through the crust.

New material pushes older rock away from the ridge.

Seafloor spreading occurs in divergent boundaries where two tectonic plates are moving away from each other. As the plates diverge, the void is filled up by upweling magma from the mantle. This causes an eruption at the boundaries causing a cascade of mountains along the ridge.  Therefore, the closer to the ridge you get, the newer the crust is.

a) Rickets

b) Osteoporosis

c) Osteomalacia

d) Paget disease

a) Rickets

Rickets occurs at the early stage of childhood due to inadequate vitamin D.

Vitamin D provides the body with higher absorption rate of calcium and phosphorus, inadequate intake of Vitamin D results into low calcium and phosphorus levels in the bones, as a result, rickets sets in.

Rickets is a disarrangement of impaired mineralization of cartilaginous growth plates in children. It can also result from lack of exposure to sunlight.
