Recall our discussions about the assumed relationships between oxpecker birds and cattle. Initial historical observations described them as mutualists. Based on the
exclusion experiments by Weeks et al. (2000), which of the following is the best explanation for the association between oxpeckers and their cow friends?

O a. They are true mutualists because the presence of the birds is associated with increased wound size and there is no significant decline in tick infestations.
O b. They are true mutualists because the birds get the majority of their food in the form of eating the ectoparasites, like ticks, off the cattle and the cattle get the
benefit of a reduced parasite burden.
O c. They are not true mutualists because the oxpecker birds only cause harm to the cattle and no benefit.
O d. They are not true mutualists because although the birds do decrease the amount of ear wax build up which could enable better…
150 patients with Crohn’s disease are given an experimental treatment in which they all drink “cocktails” containing thousands of pinworm eggs. Within one week, 72% of the patients report a reduction in their abdominal pain.
Fill in the following table.
Is there a control treatment (and, if so, what is it)?
Is there any accounting for individual variation?
Is there repetition in the experiment?
What, if any, confounding variables are not addressed in the experiment?
Can we say with some confidence that ingesting pinworm eggs is an effective treatment for the symptoms of Crohn’s disease?

- The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes?* nd 2 chool The proportion of DDT-resistant mosquitoes in a population remains constant due to O the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest. Over the next year, the finches show a death rate of…arrow_forwardIn humans, people with at least one dominant RhD allele have a Rh positive blood type.
