Proteins on the surface of the influenza virus act as antigens triggering the immune response but selective resistance = new strains of virus. Could also be added.

that will make you weak not only loose weight. So,
its energy intake= energy loss.

if the climate change then the selected area will no longer hold the required condition for the species to survive.
also an outbreak of new disease can affect all species in there.
it limits number of individuals living in so less variation?

*people will continue to hunt the animals for food

if you take intake more energy energy is loss for metabolic process and excess fat is broken down . aerobic respiration

But it would still make you lose weight? Getting equilibrium on both sides will maintain weight!

It's not really the topic that I'm struggling with.. it's just you guys with a different textbook than mine and which has other information on it which I was nor taught or read anywhere. So who knows what sort of stuff I should have known and don't. :frown:

If it helps, I've seen the other textbooks and it isn't much different. Just a little more detail. If you do the past papers, you'll just automatically sink into what you're meant to know and what you're not. There shouldn't be much that you haven't heard of or know about a little.
