The location that should have lowest oxygen concentration would be the tissue because it is the furthermost location.
Other location with lowest oxygen concentration should be in the right part of the heart. It is when all unoxygenated blood pooled before going to the lungs. But the left part of the heart will have highest oxygenated blood, so it's ambiguous.
High oxygen concentration should be found in the environment, lungs, and the blood.

Answer:
A genetic engineer would be most likely to genetically modify the chickens, with the trait being production of unfertilized eggs. (B)
A dependant variable is a variable in an experiment that is being studied or measured. A dependent variable's value depends on another.
Keeping this in mind, the dependent variable would be plant growth over time. The plant's growth is affected by its light source, the amount of time it's in the light/darkness, and the species of plant.
Hope this helps!

I'd say that the mechanism which might keep Rana aurora and Rana boylii from mating is B. temporal isolation, since their breeding seasons do not occur at the same time.
It is not anatomical isolation, since they are both frogs. It is not geographic isolation, since they meet in California. It is not behavioral isolation since they both have breeding seasons.
