Answer:
Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.
Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.
Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.

Answer:
The Kingdom of Protista
Explanation:
Organisms that belong to the kingdom Protista are unicellular, and eukaryotic (cells with a true nucleus and membrane-bound organelles). Protists can be both heterotrophic and autotrophic, and they usually move by flagella or cilia.
Answer:
Classical conditioning
Explanation:
Classical conditioning or Pavlovian conditioning is conducted on living organisms to make them associate one or more actions to a given (often familiar) stimulus or stimuli. Ivan Pavlov, in his experiment, trained a dog to associate an action, salivating for food, with the sound of a metronome.
