Certain types of cells have very low levels of metabolic activity for long time periods, but then rapidly shift to grow and divide. To undergo this shift, these cells must activate anabolic pathways. Which is one way they are able to accomplish this

The way is by generating non-catabolic, endothermic pathways where heat or energy is not lost, so that it is used in cell growth.

Large foci of cell proliferation need growth factors and good energy inputs, in addition to angiogenesis and the expression of genes that promote cell multiplication

Explanation:

The foci of cell proliferation are in cases of growth and development, such as in the situation of children or adolescents with growth cartilage or in both malignant and benign neoplasms where growth is uncontrolled and consists of atypical mitoses not controlled by genetic regulation cell phone.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom
