Reciprocal altruism can be best explained with a model proposed by Robert Trivers in 1971. Trivers hypothesized that if one indi

vidual (A) pays some cost to help another individual (B), but the cost is recovered at some point in the future (when B helps A), then natural selection might favor behaviors that lead to this type of reciprocity. In which of the following situations is reciprocal altruism likely to occur?

Answer:

Reciprocal altruism is one of the altruism behaviors in which an individual organism helps in increasing the fitness of another organism by reducing the fitness of itself temporarily in expectation of the same behavior from another organism in the future later.

It takes place in the same set of organism partners which is a continuous interaction ion in stable groups of organisms.

Thus, the correct answer would be - an ongoing interaction in the same set of partners.

Answers:

D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked.

E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.

Explanation: Explanation for these answers are below:

D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999.  In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes.  This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.

E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000.  Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.
