Question

Please help me. I need question 1 a and b

Answer 1

can you send the whole course?

Answer 2

I don't think you even read the textbook

Answer 3

if one died, then it must be because it was injected with harmful agent that it didn't have a defense mechanism to help survive
if one didn't die then it must be that it has the required mutation to fight off or that the agent injected was not harmful

scientists MUST always be able repeat experiments so they can make a better generalization of the outcome and to cover other possibilities like knowing if the survival is due to mutation or just because it wasn't harmful enough to cause death

if mouse C survived that is because heating the agent disrupted its structure and "killed" it, it is a way of saying that whatever made it harmful was no longer present so mouse C survived
