Other answers

Multiple choice answers can often be guessed at correctly by simple analysis. First eliminate the one or usually two impossible choices. Now you have a fifty-fifty chance of guessing correctly rather than a 1 in 4 chance, Also use one or another question to help you answer a different one. here is what I mean.Look at questions 1 and 5. In number 5 one can see that three of the species are mammals and the snake a reptile. Thus D is the answer here. In number 1 we now know that endothermia is a trait of mammals. We also should know that mammals have fur and mammary glands thus C is the correct answer. Q number 2 we can toss out C and D immediately. We can also throw out A. Even though ut is an adaptation for cooling off it is not behavioral. So B is correct Q 3 is D. Q 4 is A ; 6 is C; 7 is A; 8 is B; 9 is B and 10 is D.
