Answer: gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).
Explanation:
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These make these cells different to the ones produced during mitosis
The correct answer is the mouth. Digestion begins when food enters the mouth, chewed, and mixed with saliva. Food usually has complex carbohydrates such as starch in them and saliva has an enzyme called salivary amylase which can break down these complex carbohydrates into simpler molecules (i.e. dextrins). After which, these dextrins are digested further in the stomach and in the small intestine by the action of enzymes such as the pancreatic amylase which further breaks down dextrins into oligosaccharides and disaccharides. Other enzymes such as trypsin breaks down proteins into amino acids and lipase that breaks down fat into triglycerides. In the brush border of the small intestine, there are enzymes such as oligosaccharidases and disaccharidases which breaks down sugars into their most basic forms (i.e. glucose, fructose, galactose) which can be readily absorbed in the intestine. Amino acids and tricglycerides are also readilty absorbed in the intestines with the latter by the help of emulsification by bile.
