<span>This example is used to illustrate the point that there are times when context and purpose are not enough to resolve all issues or questions. Context means that you are considering your audience, where purpose means that you are understanding and contemplating why you are doing or stating something. Here, the author is illustrating how these can be unimportant to a solution.</span>
The answer to this question would be: oxygen
The presence of oxygen allows the cell to do the aerobic reaction. Using in metabolism will result in a much higher number of ATP produced.
When there is no oxygen, the cells make energy using the anaerobic reaction that gives a low number of ATP.
Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
Answer:
Uranus
Uranus' axis is tilted, so it rotates from top to bottom.
