The right answer is B.
Insulin is a hormone naturally secreted by the pancreas, specifically by specialized cells located in the islets of Langerhans. It allows glucose (sugar) to pass blood into the cells of the body. These will use glucose as energy or store it for future use.
In healthy subjects, insulin is secreted continuously. The body produces insulin according to the needs and foods consumed. For example, after a meal, the pancreas secretes additional insulin, allowing blood glucose to stay within normal limits.
Answer:
Haploid spores grows by mitosis and develops into gametophytes. In plants, there’s a little break between meiosis and the production of sperm and eggs. During that break, a separate little haploid plant grows.
In plants, meiosis occurs to produce the gametophyte. The gametophyte is already haploid, so it produces sperm and egg by mitosis.
So in other words it is important.
Hope this helps and have a great day!!!
