Human sperm cells and egg cells are called haploid, each containing 23 chromosomes

Haploid refers to a cell that contains a set of chromosomes. Haploid cell only comprise half the number of chromosomes that are present in diploids.

Haploid also means the number of chromosomes in sperm cells or egg cells, which are termed gametes. Basically, in humans, gametes are haploid cells that contain 23 chromosomes, each of which is one of a chromosome pair that exists in diploid cells. Haploid means "half."

The combination of sperm cells and egg cells is known as Diploid which has 46 chromosomes collectively. Gametes have half the chromosomes present in normal diploid cells of the body, which are termed as somatic cells.

The production of Haploid gametes occur during the process known as Meiosis, which is also process of dividing a single cell into two parts, and subsequently producing four cells. And Meiosis occurs when it is time for the reproduction of an organism.

With only a few exceptions, cells in a human body in a lifespan are diploid. During the production of a child, the child’s parents produce haploid cells, the combination of the cells produce the first cell of the child’s body.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
