Cells Cycle And Stem Cells

Question 1

Diffusion

Answer 1

The net random movement of particles from an area of low concentration to an area of high concentration.

Question 2

Mitosis

Answer 2

Normal body cell divided by mitosis

Question 3

Meiosis

Answer 3

The type of cell division that produces sex cells(sperm and egg cells)

Question 4

Osmosis

Answer 4

Osmosis is the movement of water molecules from an area of high water concentration (weak/dilute solution) to an area of low water concentration (strong/concentrated solution) through a partially permeable membrane.

Question 5

Rate pf diffusiom

Answer 5

Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen. Diffusion occurs when particles spread. … Particles diffuse down a concentration gradient, from an area of high concentration to an area of low concen
