Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created, hence option B is correct.
Male and female gametes combine during fertilization to create a diploid (i.e., having paired chromosomes) zygote.
Sex cells are used in the cell division process known as meiosis. To create four haploid daughter cells, a single diploid sex cell splits twice (meiosis I and meiosis II).
Given that the number of chromosomes in the parent cell is cut in half during meiosis, the process is frequently referred to as reductional cell division.
Haploid cells in plants result in haploid gametophytic generations, also known as gametophytes. Gametes eventually develop from the gametophytes.
Therefore, gametes are produced by the process of meiosis.

Just took the test the answer is B.
Answer:
All animals are heterotrophic and have cells with no cell wall.
Explanation:
Since animals don't perform photosynthesis or any other process to make food, and don't contain a cell wall, that is what makes them different. Protist can be both autotrophic and heterotrophic and some can contain a cell wall, but most of them don't have cell walls.

Answer:
The correct answer is glomerular capsule.
Explanation:
The glomerular capsule or the Bowman's capsule refers to a cup-like sack at the initiation of the tubular part of a nephron in the kidney of a mammal, which performs the initial step in the filtration of blood to produce urine. In Bowman's capsule, the blood filtration process is termed as glomerular filtration or ultrafiltration.
The usual rate of filtration is 125 millimeters per minute. Any small molecules like glucose, water, amino acids, salts, and urea can pass into the Bowman's space without any hindrance, however, the platelets, cells, and large proteins do not passes through.
The glomerular capsule, or Bowman's capsule, of the nephron in the kidney is responsible for the process of filtration, separating smaller molecules from larger ones.
The part of the nephron involved in filtration is the glomerular capsule, also known as Bowman's capsule. The process of filtration occurs here, where blood under high pressure flows into the glomerulus from the afferent arteriole and the filtered kidney filtrate moves into the tubule system of the nephron. This process separates smaller molecules like water, glucose, and salts from larger molecules such as proteins and cells, preventing them from being lost in urine.

Answer: Calcium
Explanation:
The mineral that is in great demand during pregnancy because it is involved in building the skeleton is calcium (option 1). Calcium is essential for the development of the fetal skeleton and plays a crucial role in bone formation. Pregnant women need an increased intake of calcium to support the growth and development of the baby's bones and teeth.
While other minerals like iron, magnesium, and zinc are also important for various aspects of maternal and fetal health during pregnancy, calcium is specifically associated with skeletal development. Adequate calcium intake is important to prevent conditions like rickets in the baby and to support the overall health of both the mother and the developing fetus.
