Answer:
C. Mutation.
Explanation:
The mutation is the source of all genetic variation. There are two types of mutations. One is the natural mutation, and another is the artificial mutation. The natural mutation occurs due to the environmental cause, and humans using various mutagens do artificial mutations.
These two types of mutations always bring variation in any organism. This variation can be positive or can be negative too. Natural mutation is not possible to control so that anything can happen. Either positive or negative changes can occur. But in the case of artificial mutation, in 90% cases, positive results come in genetic variation.
Answer:
She will obtain results to support -or reject- her working hypothesis. These results are subjected to statistical analyses in order to confirm that they are statistically significant
Explanation:
The scientific method is a rigorous process that consists of raising a working hypothesis, which is tested by experimentation or observational procedures and analysis of the results. The statistical analyses may have key roles during this procedure. In an experiment that involves statistical analyses, the results are subjected to statistical measures to evaluate the significance level and thus confirm (or reject) the statements made in the working hypothesis. The p-value is one of the most used statistical measures to determine if differences are due to randomness, or they are statistically significant.
Answer:
<u><em>Oxygen</em></u>
Explanation:
Cellular respiration can be described as a process by which cells produce carbon dioxide and water from oxygen and glucose. Huge amounts of ATP is generated by this process. This ATP is used to carry out the normal functions of a cell.
If the oxygen supply to the frog species becomes low, then the process of cellular respiration will also slow down. Hence, by altering the amount of oxygen, the amount of ATP can be altered.
