Which is a correct statement about gametogenesis?

1 answer:

7 0

In gametogenesis, germinal cells multiply by mitosis and mature gametes are formed by meiosis.

Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.

Answer:

Epigenetics.

Explanation:

Epigenetics is the study of phenotypic changes which are heritable but not related to changes in the DNA sequence. It is influenced by several factors including the environment.

An example of epigenetics is DNA methylation: addition of methyl group to some part of the DNA that prevents that part from being expressed. Other examples include history modifications.

In summary, Epigenetics describes inheritance through other mechanisms than through the DNA sequence.

Sally and Maria were running around the track during PE. They were not happy and decided to stop and rest once they got to the b

pogonyaev

With the graph attached below you can determine when was the moment that
Sally tripped and fell.
You can also see that they run for 4 minutes before starting to rest. Then, after resting 10 minutes (starting at the 9 min mark and ending at 14) they started running a bit, that's why the line is not at zero anymore. After moving a bit, between 15 and 16 min mark, they stop distancing for one minute. So the answer is: Sally fell at the 15 min mark.
