Q

Name 2 pros of stem cells?

A

-grow organs (organ donations as there is a small supply+ long wait for organs )
- curing/treatment of diseases ( growing neurones for dementia)

Q

Why are chromosomes/DNA replicated?

A

They are replicated in the parent cell, so more are now 2x as many chromosomes in the cell (46 to 92)

Q

What is mitosis used for ?

A

Growth + repair of cells + tissues

17
Q

What is diffusion?

A

The net movement of particles from an area of higher concentration to an area of lower concentration

18
Q

What is concentration?

A

The amount of substance per unit of volume

19
Q

What is rate of diffusion?

A

Is how much diffusion takes place over a certain period of time/ how fast diffusion occurs

20
Q

What happens to the rate of diffusion when temperature increases?

A

As temperature increases, the particles will gain more kinetic energy so the rate of diffusion increases

21
Q

What is concentration gradient?

A

The difference in the concentration

22
Q

What does larger surface area to a small volume mean?

A

It means a small diffusion pathway, short distance the particles need to travel

23
Q

What is osmosis?

A

The net movement of water particles from a higher concentration to a low concentration across a partially permeable membrane
