# A level Biology breathing question watch

1. Seals are mammals. They have lungs and must breathe air. They can dive and remain under water for a long time. The table shows the flow of blood to the lungs and to the diaphragm in a seal when it is on land and when it is under water. (b) Explain why the figures in the table are given per gram of tissue.
2. Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

Just quoting in Danny Dorito so she can move the thread if needed

No table = no figures = no responses.

You don't really need the table to answer this, you can quite easily assume that the reason the figures are given per gram of tissue is to negate the fact that the more tissue you have the more blood you're going to have flowing to it which will completely ruin the results

You're missing the point - it's the principle of it. Particularly given the OP has just dumped the question and expected an answer without even attempting it him/herself, or had the simple manners to even ask if someone could please help!
