Name the structure that allows motility in the following groups: amoebozoa, excavates, and ciliates. What will be an ideal response?

What can be said about the transfer of fluid from the glomerulus to Bowman's capsule?

A. It results from active transport. B. It transfers large molecules (e.g., proteins) as easily as small ones. C. It is very selective as to which small molecules are transferred. D. It is mainly a consequence of blood pressure force-filtering the fluid. E. It usually includes the transfer of red blood cells to the nephron tubule.

In an organism, X, it is found to be impossible to generate loss-of-function mutants for most genes. There is an alternative method of introducing random mutations that can later be screened for the gene(s) in question

This can be accomplished by using insertions due to what structures?

In most respects, the second meiotic division is identical to a normal ________ division.

Fill in the blank(s) with the appropriate word(s).

Guppies from Trinidad form two distinct populations that differ in several life history traits. These traits appear to relate to the local predator populations, pike-cichlids or killifish. Which experiments would best test the heritability of these

traits? A) Raise both populations with cichlids to see if the population of smaller, faster-maturing guppies reproduces more quickly. B) Raise both populations without predators to see if they maintain their life history traits. C) Introduce cichlids into a habitat with killifish. D) Provide additional food to the guppies from cichlid habitats to see if they will grow to the same size as guppies from the killifish habitat.
