Explanation / Answer
Hi Answer:
Q. Which of the following statements is compatible with Darwin’s theory of evolution?
Answer: Option A, B and C
Explanation: Individual who is most suitable to environmental conditions has the highest survival chance. It's not a luck. Survival depends on environmental factors and conditions.
Q. Which of the following statements about human population in wealthy countries is incorrect?
Answer: Option D. (Life history is r-selected).
Q. For asexual organisms, speciation often involves reproductive isolation.
Answer: False, because for a sexual organisms reproductive isolation is not valid
Q.Which of the following is not a pre-zygotic reproductive barrier?
Answer: Option C (Hybrid sterility)
Q. In the Hardy-Weinberg equation, p2 + 2pq + q2 = 1, q2 represents the
Answer: option D (homozygous recessives)

Answer: Option C (Population)
Q. Which of the following causes populations to shift most quickly from an exponential to a logistic population growth?
Answer: Option B (competition for resources)
Q. The founder effect can cause the loss of alleles.
Answer: True
Q. According to your textbook, the extinction of the dinosaurs about 65 million years ago was likely caused by a super volcano.
Answer: False (the cause of dinosaurs extinction is still a mystery, climatic change, diseases, changing plant communities, and geologic events could all have played a role. But it’s sure that they didn’t extinct due to super volcano eruption)
Q. The biological species definition does not apply to fossils.
Answer: True, because biological species are alive they can reproduce and able to produce offspring’s but fossils are not alive they cannot produce offspring’s that’s why concept of biological species is not applied on fossils.
