Question #1
Bacteria reproduce asexually, whereas most plants and animals reproduce sexually. Which is the better method?
A.
sexual reproduction, because it produces more variation
B.
Neither method is better—each is effective in different environments for different kinds of organisms.

asexual reproduction, because binary fission is more efficient

sexual reproduction, because there are more plants and animals than bacteria

asexual reproduction, because there are more bacteria than plants and animals

Question #8
Which of the following expresses Mendel's law of segregation?
A.
Genes do not influence each other with regard to sorting of alleles into gametes.

C.
Two alleles of a gene separate during meiosis and end up in different gametes.
D.
All dominant alleles of different genes divide into different cells from the recessive alleles.
E.
Gametes with recessive alleles will fuse only with each other.
