Homework Answers
Ans) anti predator behaviour
Explaination: due to clump distribution large number of organism present in population which provide protection against predators so clump distribution of population is an antipredator behaviour.

1/ a/ Explain how each of these relationships may affect the distribution of animals: predator-prey, parasite-host, competition, mutualism, commensalism. b/ Outline the evolutionary effects of predator-prey relationships on the characteristics of both the prey and the predator.

Which dispersal pattern, random uniform, or clumped, would cause the most problems for a random sampling approach? In bluejay birds, the offspring may remain and assist the parents in rearing additional young because a.there are no "costs" for being social b.the offspring have no chance of obtaining a necessary territory otherwise c.competition does not occur among these birds d.predation rates are variable e. predation influences bet-hedging in these long-lived birds

Is the human population clumped, random or uniform? How might the patterns have changed with the development of technology? Justify your answer. Consider the four demographic characteristics relating to biotic potential listed in the text: 1) usual number of offspring per reproduction, 2) chances of survival until the age of reproduction, 3) how often each individual reproduces and 4) age at which reproduction begins. Relate each factor to the human population, rating each one as contributing to a high or...

12. The ideal free distribution (IFD) involves individuals that have ideal information and are free to move about, while the ideal despotic distribution (IDD) involves individuals who have ideal information but are sometimes excluded from locations by better competitors. The IDD is to the IFD as a. Territoriality is to clumped dispersion b. Conditional strategies are to alternative strategies C. Migration is to reproductive value d. Anisogamy is to sex allocation 13. You are at home over spring break and...

Competitive interactions can occur within species (intraspecific competition) or between species (interspecific competition). These interactions are often intense, but intensity is virtually always a part of one of the two types of competition. Which of the following helps explain this observation? Multiple Choice Interspecific competition is usually intense because different species cannot partition resources when resource requirements overlap Introspecific competition is usually intense because individuals have nearly identical resource requirements Interspecific competition is usually intense because it may involve predator/prey...

Individuals with premutation length repeats in FMR1 may have some of the phenotypes of Fragile X but not others, which is _____________; for example, some individuals may have cognitive deficiencies, while others might have late onset ataxia. In addition, some individuals will have no phenotypes of the condition at all, due to ____________. a. incomplete penetrance; variable expressivity b. variable expressivity; incomplete penetrance c. complete penetrance; variable expressivity d. variable expressivity; complete penetrance

A new type of intensive physiotherapy is developed for individuals who have undergone spinal surgery. Due to limited hospital resources it can only be given to 3 out of 10 patients. The patients are aged: 15 21 26 32 39 45 52 60 70 82 Explain how a permutation test could be used to investigate whether use of the physiotherapy is related to patient age, (i.e., whether there is a policy to give the...
