Exam 4: Biodiversity and Evolution

For every shark that injures or kills a person every year

The variety of genes within a species or population is called the

The biological diversity of the Earth is only a function of the number of species on the Earth.

It can be said that amphibian populations are declining worldwide,

Which of the following characteristics must be true in order for a trait to be impacted by the forces of natural selection and then play a role in the process of biological evolution?

Species whose roles have a large effect on the types and abundance of other species in an ecosystem are called ___________ _____________.

Clearly explain how large-scale mass extinctions can actually lead to evolutionary opportunities.

Which of the following statements best describes insect species as a group?

Houseflies would probably adapt to an environmental change much more quickly than a human.

Sharks are all carnivorous.

In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely. -Since the mutation produced a specific wing trait that was passed on, the mutation must have occurred

Which of the following statements is false?

Clearly explain the relationship between the geologic process of plate tectonics and the biological process of evolution over geologic time.

The shifting of tectonic plates can cause ____________________.

Biological evolution is the process by which the genetic composition of a(n) ____________________ changes over time.

A practice that involves cutting off fins of a shark and then returning the shark to the ocean without the fins they need to survive is called ____________________.

Most of the historic evidence that supports the scientific theory of evolution comes from ____________________.

Holding the pen or pencil for taking this exam is one of the things you can do as a human because you have____________ ____________.

The bird species known to forage in shrublands after they have experienced a wildfire are very different from the bird species that forage in shrublands that have not burned. In fact, the bird species foraging in burned shrublands are closely correlated with the age of the burn, or the number of years that have passed since the fire. Certain birds forage at one-year post fire, different birds forage at three-years post fire, and so on. These birds could be called
