Answer:
Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.

Answer:
Simple cuboidal epithelial tissue is specialized for diffusion and absorption. The reason our kidneys function the way they do is because of the movement of water and salts in and out of the kidney tubules.Likewise, the cuboidal shape of the cells allows greater surface area for absorption to take place.
Answer:
The nuclear membrane dissolves, and spindle fibers form.
Explanation:
This occurs during prophase. the chromosomes become shorter and thicker. The centrioles migrate to the opposite poles. The nuclear envelope is broken down, the nucleolus disappears, and microtubules attach to the chromosomes at the kinetochores present in the centromere. Microtubules that are associated with the alignment and separation of chromosomes are referred to as spindle fibers. Chromosomes visible under a microscope are connected at the centromere. In meiosis, the homologous chromosomes break in their DNA strands at the same point, following a recombination of the fragmented parental DNA strands into non-parental combinations, known as crossing over.
Answer:
The correct answer is "cleaves the Holliday intermediate by replacing one RuvA with RuvC".
Explanation:
RuvABC is a three proteins complex that is critical for DNA repair in bacteria. RuvAB is a helicase that is comprised of two of the tetramers of the complex that besides mediating branch migration, cleaves the Holliday intermediate by replacing one RuvA with RuvC. RuvAB perform its molecular activity by by localized denaturation and reannealing.
