Suppose Inverness was considering offering a special add-on to its standard Dental insurance. For an additional 1 dollar a month a family could be fully covered for professional teeth whitening, something that normally would cost five thousand dollars a treatment. The whitening procedure would erase any stains that build up over time as a result of drinking too much coffee. Would this benefit create an adverse selection and/or moral hazard problem? If so explain why, and how the benefit could be better designed to address these issues.

According to the antagonistic pleiotropy hypothesis of aging, we tradeoff survivorship later in life for elevated reproduction early in life we tradeoff reproduction later in life for elevated survivorship early in life we evenly invest in survivorship and reproduction throughout life

Explain the phrase,"survival of the fittest."

A scientist discovered a new factor, Sneezy, to be important for the central nervous system development. This factor is concentrated at the posterior end of the neural tube during development. If a mutation inactivates the activity of Sneezy, which phenotype below would be the most likely result of this mutation? Smaller brain with longer spinal cord. Fused brain hemispheres and overdeveloped spinal cord. Larger brain with shorter spinal cord. Underdeveloped brain and underdeveloped spinal cord. Overdeveloped brain and overdeveloped spional cord.

The nature versus nurture debate is one of the oldest issues in psychology.  Explain the four environmental factors that may affect the growth and development of humans and their educational implications

Darwin's concept of evolution "the theory of decent with modification through variation and natural selection" can best be demonstrated by which of the following examples?   a. A giraffe stretches his neck to reach higher branches. The exercise of stretching up strengthens the muscles in the giraffe's neck and legs. This ability to stretch is also seen in the giraffe's offspring.   b. A monkey accidentally drops her fruit in the salty water of a bay. She recovers the fruit and eats it. She discovers the fruit is cleaner and tastes better after it has been in the salty water. She continues to wash the fruit in the bay before eating it. Her offspring see what she has done and also wash their fruit in the salty water. Soon, the whole population of monkeys is washing their fruit.   c. Several turtles hatch from a clutch of eggs buried in the sand on a beach. One of the turtles is the color of the sand; the others are darker in color. The turtles scurry toward the water,…
