C. Crossing Over
Explanation:
Crossing over, also called recombination, is the process by which non-sister chromatids of homologous chromosomes exchange a segment of their chromosomal material with one another. The process of crossing over occurs only in the prophase I stage of meiosis.
The process is responsible for genetic variation in the gametes produced, thereby, leading to organisms that are genetically unique.
<span>True.
</span>We use the magma of the Earth to heat buildings with geothermal energy, this statement is true.

food, water, cover, space, and the arrangement of the previous 4 (animals need to be able to GET to those 4 elements)
Boiling the broth in both flasks ensured that any pre-existing organisms such as bacteria were killed.
Had the broths not been boiled, both the flasks would have had bacterial growths in them, making the experiment inconclusive. This removal of pre-existing organisms when conducting investigations is still carried out, such as when creating a colony of bacteria on a petri dish or preparing a batch of alcohol through fermentation.
