A group of scientists are studying a population of horses. They have been collecting data on the characteristics of these horses for many generations. You are trying to find out if their study is on natural selection or artificial selection. What questions could you ask the scientists that would help you learn which process is taking place in their study? (AKS 4e, DOK 2)

A.
Were most of the new generation of horses better adapted to their environment? Were two horses bred to create a desired trait?

B.
Were most of the new generation of horses less adapted to their environment? Were any two horses bred to create a random trait?

C.
Were most of the new generation of horses less adapted to their environment? Were two random horses bred to create a desired trait?

D.
Were most of the new generation of horses better adapted to their environment? Were any two horses bred to create an undesirable trait?

Seen in some gram-positive bacilli, occurs when only the inner portion of a cell wall is deposited across the dividing cell. this new cross wall puts tension on the outer layer of the old cell wall. eventually, the outer wall breaks at its weakest point with a snapping movement that tears it most of the way around. the daughter cells can then remain hanging together almost side by side being held by a small remnant of the original outer wall. choose from the following statements the ones that correctly discuss reproduction using binary fission in a bacterial cell. select all that apply. view available hint(s) select all that apply. due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome. each daughter cell will contain an equal number of organelles. the daughter cell will be a permanently smaller copy of the mother cell but will contain a complete genome. each daughter cell is an exact copy of the other, both genetically and morphologically

Cathy hypothesized that corn would not grow in mud. to test this hypothesis, she took corn kernels and placed 5 in mud, 3 in soil, and 2 in water. to her surprise, the kernels in the mud grew faster than the kernels in the soil. what error might have caused these unexpected results? a. wrong hypothesis b. not enough variables c. undefined control d. too many variables
