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).
Enzymes are proteins that are biological catalysts
They reduce the activation energy required for a reaction to occur and thus speed up a reaction
Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)
They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's
They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.
They aren't used in the reaction so they're re-usable.
If it isn't one of these then it is not one of the properties of enzymes
Saturated fats or lipids form animal body fat that is used for stored energy and insulation.
A.Is false so maybe put “Cells are so tiny that you need a microscope in order to see them”
B. True
C. True
D. Eurkaryotes are complex cells where the necleus is the most important part.
E. True
F All living things are made up of one of more cell
A chromatid is each of the two threadlike strands that make up DNA, a chromatin is the materials that make up chromosomes, and a chromosome is the threadlike structure made of nucleus acids found in the nucleus of a cell and contains genetic information in the form of genes
