What types of cells in your body are no longer undergoing mitosis

Answers

Nerve and muscle are the cells that no longer undergo mitosis.

What are Nerve cell and muscle cell?

A cell must go through either mitosis or meiosis in order to divide. Since neurons are somatic cells, they must go through mitosis. Centrioles must travel to the poles and generate spindle fibers that pull the chromosomes in order for mitosis to take place.

Neurons cannot undergo mitosis because they lack centrioles, which prevents them from dividing.

In our nervous system, each nerve cell has a unique location. Its sole responsibility is to transmit a signal from one place to another. In a particularly complicated system, adding more nerve cells might disrupt these extremely precise connections.

Therefore, Nerve and muscle are the cells that no longer undergo mitosis.

These are applicable to multicellular organisms thoughas they are needed for the cells to sustain their functions alone andeventually coordinating with one another. Cells are the basic unit of life, when grouped together, they aretissues. When tisuues are grouped together, they are organs and organ systemscomprises of two or more organs to function and overall, creating an organism.

Answers

Renewable energy is exactly what it says -- it's renewable. Meaning, you can continue to reuse it or make more of it in a never ending cycles. Examples of a renewable energy could be trees (wood). You can keep growing trees and harvesting them.

Fossil fuels are things like oil or petroleum, they cannot be "grown" again, and are a one-time use.

Renewable energy has more benefits then that of fossil fuels because you can reuse renewable energy and keep the never-ending circle of energy going, unlike fossil fuels which can run out.
