Question

no explaination is needed

7. Which of the following is not a term used to describe animal dispersion? a) Long distance b) Uniform c) Random d) Clumped 8. Population growth may be affected by a) predation but not competition. b) competition but not predation. c) competition and predation. d) neither competition nor predation 9. Batesian mimicry is when a) a harmless species imitates a harmful species b) two or more unpalatable species mimic cach other. c) a harmful species imitates a harmless species. d) two harmless species imitate cach other. 10. Why do some invertebrates, such as lobsters, show a "stair-step" survivorship curve? a) Many invertebrates mate and produce offspring on multiyear cycles. b) Within a species of invertebrates, younger individuals have a higher survivorship than older individuals. c) Many invertebrates moult in order to grow, and they are vulnerable to predation during their "soft shell" stage. d) Many invertebrate species have population cycles that go up and down according to the frequency of sunspots. 11. Regeneration (the re-growth of lost body parts) normally follows a) all types of asexual reproduction b) fission. c) budding d) fragmentation 12. Evidence that parthenogenic whiptail lizards have evolved from ancestors that reproduced sexually includes a) creation of haploid offspring b) sex reversal in large, older females for successful reproduction. c) requirement for male-like behaviour in some females before partners will ovulate. d) fusion of two female gametes for the production of diploid zygotes. 13. Genetic recombination resulting from sexual reproduction is beneficial as it allows for a) passing on deleterious mutations to the offspring. b) adaptation and change in an unstable environment c) long-term survival and persistence of certain genotypes in stable environments d) rapid population growth

Answer 1

Question 7) option a, long distance

Uniform distribution involve, distribution of animals evenly.

Random distribution involve random distribution which do not follow any pattern

Clumped distribution involve, distribution in a clump.

Long distance is not any kind of distribution

Question 8) option c, both competition and predation.

Question 9) option a, when a harmless species imitate harmful species.

Question 10) option c, many invertebrate molt in order to grow , and they are vulnerable to predation during their shoft shell stage.

Question 11) a, a type of asexual reproduction

Question 13) option B, adaption and change in an unstable environment
