A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every si
x months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population? Yellowstone National Park expanded its borders. A population of wolves was introduced into Yellowstone National Park. The amount of disease in the deer population decreased. More grass and shrubs were planted in Yellowstone National Park.
I would have to go with B, since those that had certain traits that wouldn't aid them against the wolves would have been eaten, and those that did would have been able to pass on their genes. Hopefully this is helpful to you in some way.
B: <span>They can differentiate into more </span>cells<span> than adult </span>stem cells can.<span>They can differentiate into more </span>cells<span> than adult </span>stem cells<span> can.</span>
<span>Option C is a true statement that compares the two gasses in a simple factual way. Both are compound gasses formed of Carbon (C)and Hydrogen(H).
Butane has a formula of C4H10
whilst Methane has a formula of CH4</span>
'DNA fingerprinting' or DNA typing (profiling) as it is now known, was first described in 1985 by an English geneticist named Alec Jeffreys. Dr. Jeffreys found that certain regions of DNA contained DNA sequences that were repeated over and over again next to each other.
