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

</span>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. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. 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.<span>

Growth hormone and insulin are protein hormones that regulate carbohydrate metabolism by hepatocytes (liver cells) through the a
aleksklad [387]

Answer:

The data from the experiment support the claim that the similar regulation of carbohydrate metabolism  by hepatocytes occurs when the cells are treated with growth hormone or insulin results from the activation of different signaling pathways

Explanation:

If we take a look on the graph, it shows increase in the phosphorylated protein when the growth hormone or insulin is applied to the cells with the passage of time. At  15 minutes , it reaches to its highest level but after 15 minutes of addition of growth hormone and insulin, the level of phosphorylated protein decrease when the time exceeds from 15 minutes to 240 minutes. So it is concluded that growth hormones or insulin increase the level of phosphorylated protein.

How does increase in temperature disturb water cycle ?
Alja [10]
Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air. Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world.
