With negative pressure breathing, the muscles that move the ribs and diaphragm are distant from the absorptive alveolar surfaces. What difficulty(ies) could occur if the muscles were around each alveolus and had to expand each alveolus to suck in air?
A. Interspersed muscle tissue would take up much space and the lung-muscle volume would have to be much larger. B. Adding a third tissue to the intimate alveolar-capillary complex would increase the problems with disorders and diseases. C. Muscle tissue would get in the way of absorption of gases across the air-to-capillary border. D. Since muscle cells only contract and relax, it would be difficult for a few cells to cause alveolar expansion. E. All of the choices are correct.
Like humans, cats can experience kidney failure. Unlike humans, however, cat kidney dialysis as a treatment option is not widely available and used. Rather, efforts are made to treat any complications that arise from failing kidneys such as low potassium
or high phosphate levels. When low potassium levels are identified, potassium supplements are given to return cells to a balanced potassium-water level. This is an example of an effort to maintain A) osmoregulation. B) thermoregulation. C) convection. D) evaporation.

Which of the following statements is true?
(a) The intron structure of most genes is conserved among vertebrates. (b) The more nucleotides there are in an organism's genome, the more genes there will be in its genome. (c) Because the fly Drosophila melanogaster and humans diverged from a common ancestor so long ago, a gene in the fly will show more similarity to another gene from the same species than it will to a human gene. (d) An organism from the same Order as another will be more likely to have a genome of the same size than will a more evolutionarily diverged animal.
