Answer:
B. It was passed to the individual by a gamete from the father.
Explanation:
<u>DNA is transferred</u> to the next generation <u>via gametes</u>, which are produced during <u>meiosis</u>. During meiosis, <u>half of the genetic material</u> is <u>transferred</u> from parent cell to their gametes. Therefore, among the given options, only <u>B is correct</u>.
Option A is not correct because it talks about <u>somatic cells;</u> whereas, in somatic cells, <u>genetic material is not transferred half</u> rather duplicate first and then a complete duplicated set of genetic material is transferred.
Option C is also not correct because only <u>one gamete (sperm)</u> fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.
Answer:
The dependent variable is the biological sex of the alligator hatchling.
Explanation:
A hypothesis is essentially a suggested explanation for a specific phenomenon. These hypotheses attempt to offer well-tested reasons for certain observations through experiments.
Experiments are usually carried out under a variety of different conditions to test various hypotheses. To ensure reproducibility, accuracy, and validity of results, several factors must be identified when planning experiments.
For instance, various independent variables are strictly altered and observed while controls are kept constant - this ensures validity and can indicate if the experiment was influenced by external factors. Here, the factor being changed or tested is the temperature, and the factor being observed is the resulting biological sex of the organism.
