Answer:
sugar
Explanation:
The Skinny on Obesity is a documentary made by Dr. Lusting and his colleagues from the University of California, San Francisco. It aims at decoding the obesity epidemic. It demonstrates the reasons for rising obesity, relationship between stress and obesity and how the future generations are going to be impacted by it.
In the documentary, sugar was shown as the main contributor to the obesity problem. Addition of sugar to almost all the processed food items has led people to consume huge amounts of sugar unknowingly. The extra sugar is converted into fats which ultimately makes a person obese. It can also lead to problems like insulin resistance, which further cause obesity.

The process by which a stimulus increases the probability that a preceding behavior will be repeated is D) reinforcement.
Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying.
Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
Convergent evolution is the independent evolution of similar features in species of different lineages. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.
