Write a five sentence paragrgh explaining the cell cycle

The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.

New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.

Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.

The two main parts of the cell cycle are mitosis and interphase.

Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”

The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.

Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.

Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
