Question 8

Which statement is true regarding our knowledge about the origin of life?

Accepted Answer

The origin of life is believed to have occurred about 3.8 billion years ago, based on scientific evidence and theories. The other options are not accurate, as the origin of life predates the evolution of species, adaptation, and natural selection, and cannot be studied using scientific methods.

Question 13

A population of squirrels becomes divided into two halves by a flooding river. Over time, the river becomes larger and the populations are not able to interact for many years. Which of the following is the most likely outcome?

Accepted Answer

Geographic isolation, which is caused by the flooding river in this case, can lead to genetic divergence and ultimately speciation over time. The lack of interaction between the two populations can allow for separate populations to evolve separately and potentially become different species. The other options (A, C, D, E) are less likely outcomes in this scenario.

Question 14

Sharks are especially vulnerable to population declines because ____.

Accepted Answer

Sharks have a low reproductive rate, with slow growth and late maturity, as well as few offspring per generation. This means that their populations are slow to recover from overfishing or other threats, making them especially vulnerable to population declines.
