Answer 1

1) E

2) C

3) A

Answer 2

you're being perplexed approximately what organic determination is. organic determination isn't a stress. it extremely is an result. if it have been a stress, we could all be believing Lamarck and not Darwin. organic determination isn't the mechanism of something. It the result. the mechanism is mutation or new genetic information. you may positioned the nutrition greater and better, even if it won't reason a giraffe's neck to get longer. mutation will and if the giraffe's earnings from it (i.e., extra functional nutrition get admission to) then it is going to probable persist. once you seem at it you assert it is organic determination. even if it extremely is the mutation this is the reason. organic determination isn't a stress that motives mutation

Answer 3

first question - e
62. c (actually it's total of all the alleles -versions of genes- in the population but this is the closest by far)
64. a

Answer 4

E
C
A

Evolution doesn't violate the second law of thermodynamics. Life might if you use a crude inaccurate definition. It doesn't violate it because it uses energy to bring order.

Answer 5

evolution is anti science. it breaks the second law of thermodynamics several times. no true science can do it once without being dispelled as nonsense.would you get into a plane that didn't comply with the basic laws of drag and lift, and crashed every time passengers boarded it? of course u wouldn't.I could answer the questions that u want but id be doing you a disservice my friend..

Answer 6

evolution? no such thing. animals will adapt to their surroundings to some degree,but thats it.how many "genetic mutations" do you suppose it would take to develop sight? how would those mutations benefit the animal during the lengthy process? even if an eyeball was created by a freak of nature,what are the chances the brain would evolve the tools to utilize it?

evolution.

get serious.
