Question
What characteristics of crop pests favor the development of pesticide resistance?
a. widespread use of pesticides b. application of ineffective pesticides c. short generation times in insects d. A and C
If chimpanzees and human genomes differ only about 1.3% at the level of DNA base pairs, then how can we explain the dramatic differences in appearance, behavior, cultures, etc., between humans and chimps?
There is a correlation between increased rates of divergence with known functions of alleles in humans and chimps.
Natural selection has been acting on clusters of genes associated with both survival and reproduction in humans and chimps.
Important differences exist in the expression of genes in humans and chimps.
Two of the above are needed to explain the differences.
In the absence of competition from other males:
Female chickens mated more often with the male present.
The quantity of sperm a male used to inseminate a female decreased.
Once a male has inseminated a female, additional sperm may do little to increase the probability of fertilization.
Both B and C
Which of the following statements would be the best fit to the variational process, proposed in Darwin's innovative concept of evolution by natural selection?
In this process, the group changes because each individual member changes.
In this process, the group changes because some factor sorts among the variants in the original group of members.
In this process, variation is not important.
all of the above.

Explanation / Answer
Widespread use of pesticides favours the development of pesticide resistance in crop pests.
Hence, the correct option is (a) widespread use of pesticides.
Natural selection has been acting on clusters of genes associated with both survival and reproduction in humans and chimps, and important difference exist in the expression of genes in humans and chimps.
Hence, the correct option is (d) two of the above needed to explain in the differences.
The correct option is (d) both B and C
The correct option is (a) in the process, the group changes because each individual member changes.
The correct option is (b) connected evolutionary change to environmental fit.
The correct option is (d) all of the above.
The correct option is (b) mutations are one source of genetic variation.
Question 17: No figure available
Question 18: The correct option is (d) all of the above.
Question 19: Mutation is a major source of variation in populations of organism.
Hence, the correct option is (b) mutation.
Question 20: Phenotypes are the result of both environment and genotype.
Hence, the correct option is (b) the effects of both environment and genotype.
The correct option is (c) significant differences in behaviour have evolved in populations due to predation stress.
The correct option is (b) a pedigree tells us about the ancestry of individuals, while most phylogenies tell us about the ancestry of populations.
The correct option is (b) Using these analogous traits in building an evolutionary tree might cause us to incorrectly infer a closer phylogenetic relationship between these species than actually exists.
Question 33: The correct option is (a) technique for evaluating which branches on a particular tree are best supported by the data sets.
No figure available.
