<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>

Explanation:
Explanation:
This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond. An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.

None of the provided choices provide a completely correct answer. In fact, 75% of humidification takes place in the nose and mouth, with the rest taking place in the trachea. When you breath in, mucous
membranes inside the nose and mouth release
moisture to air. It is estimated that the average adult evaporates 200 to
300 ml of water per day during this process. The process is very efficient: while breathing in through
nose or mouth, the mucous membranes are cooled down. During breathing out, this cooling effect causes condensation of some of the moisture in the air coming from the
lungs, thereby moisturizing the mucous membranes
