Well that would be somewhat correct.... however not all organism mate and produce offspring, most higher orangism can only reproduce through sexual means. However some organisms don't rely on mating, and can merely split themselves in half. Starfish, for example can produce another of themselves when a limb is cut. This is called Asexual reproduction.

Answer:

a. Glucagon is released by the beta cells of the pancreatic islets of Langerhans.

Explanation:

When the body is fasting, the pancreas releases glucagon so that your body can produce glucose. Glucagon is a protein hormone made and secreted by alpha cells from pancreatic islets (or islets of Langerhans).

The islets of Langerhans are a special group of cells in the pancreas that produce not only glucagon, but also insulin. These substances act as important regulators of sugar metabolism.

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. To have enough DNA

ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
