# Basic maths problems applied to biology Watch

1. Hi can anyone help me with these mathsy biology problems? Apparently theyre quite basic maths, but I'm bad at applying maths. They are stretch and challenge problems so I'm not tested on them, its just a learning experience. I've given them a go, but I'm really struggling Can anyone else solve them? For part one, i got like 204000:1 but i think this is wrongfor part 2 I got 900and for part 3 I really wasn;t sure. Is it 300^3 or something?

Part 1 and 2 look OK to me.

How did you calculate 3?
You are told how many base pairs there are and you worked out how many base pairs code for a protein.

5. Diffusion: movement of substance from an area of high concentration to one of low conc-n. May be draw a pic with numerous molecules on one side less on other side, and an arrow from the first to 2nd.

Osmosis: Movement of water from area of high water potential to one of low water potential. Draw droplet shapes in similar way to first way (diffusion)

Active transport: Movement of a substance using energy therefore against a conc-n gradient i.e. from low to high conc-n. Perhaps draw pics of honey bottles (representing glucose!) shapes having "ATP" written inside them being pulled in (arrow).

I assume you are a girl, so I am sure your graphic imagination is better than mine!
