Answer:
I believe the options are:
A) The diagram shows crossing over. Crossing over increases the genetic variation of the gametes produced in meiosis, by allowing for different allele combinations than present in the parents. This results in greater diversity in the offspring produced.
B) The diagram shows a chromosome mutation called translocation. Translocation introduces new traits into the gene pool of the gamete by trading genes between nonhomologous chromosomes. This results in greater diversity in the offspring produced.
C) The diagram shows crossing over. Crossing over introduces new traits into the gene pool of the gamete by trading genes between homologous chromosomes. This results in the formation of more diverse gametes.
D) The diagram shows a chromosome mutation called inversion. In inversion, a segment of a chromosome is reversed end to end. Inversion rearranges the genes on a chromosome, providing more diverse gametes.
The correct choice is: A) The diagram shows crossing over. Crossing over increases the genetic variation of the gametes produced in meiosis, by allowing for different allele combinations than present in the parents. This results in greater diversity in the offspring produced.
Explanation:
Crossing Over:
- Crossing over occurs in the Prophase 1 of Meiosis 1.
- By definition, it is the exchange of chromosomal segments between non-sister chromatids of homologous chromosomes.
- Through exchange of genetic segments, crossing over introduces genetic variations in the gametes.
- Genetically variant gametes fuse to produce an individual that varies in characteristics as compared to the parents.
The right option is; C. Inherited mutations exist in all cells in the body and somatic mutations only exist in the cell type that mutated.
Inherited mutations are gene mutations that exist in almost every cell in the body throughout an individual’s life. Inherited mutations are inherited from a parent and can also be transmitted. They are also called germline mutations because they exist in the parent’s egg or sperm cells (gametes).
Somatic mutations are gene mutations that exist in only certain cell types that are mutated, not in every cell in the body and it take place at some time during an individual’s life. Somatic mutations are not inherited and cannot be passed. They are caused due to environmental factors (such as cigarette smoke or ultraviolet (UV) radiation) or due to error during DNA replication.
<span>The appropriate response is a cork. The cell was first found and named by Robert Hooke in 1665. He commented that it looked peculiarly like cells or little rooms which friars occupied, in this way determining the name. However what Hooke really observed was the dead cell dividers of plant cells (cork) as it showed up under the magnifying lens.</span>

The correct answer is d.
Carbohydrates are a very important part of an athlete's diet, since they provide the necessary energy for competition and endurance, but also help in the process of muscle gain.
The amount of carbohydrates that Shana should consume depend heavily on the intensity of her exercise activities. For a moderate level of exercise, which equals to 1 hour of exercise daily, a person should consume 5-7 g/kg of body weight. For a high level of exercise (1-3 hours of daily exercise), a person should consume 6-10 g/kg.
Guessing that Shana will perform a high level of exercise and based on her weight (135 lb or 61.2 kg), Shana should consume 366 to 610 g of carbohydrates daily.
