Answer:
Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.
Explanation:
<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.
Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.
This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.

Answer: If crossing over did not occur during meiosis, there would be less genetic variation within a species. ... Also the species could die out due to disease and any immunity gained will die with the individual. Two types of gametes are possible when following genes on the same chromosomes. If crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes.
Explanation:
Meteoroids are Smaller because they are fragments of a comet, or asteroid
Answer:
The correct answer would be non-disjunction.
Down syndrome refers to the genetic disease caused by the non-disjunction of chromosome number 21.
Non-disjunction refers to the event in which the homologous chromosomes or sister chromatids fail to separate properly during a cell division.
In Down syndrome, the sister chromatids of chromosome 21 fail to separate properly which results in the formation of a gamete with 2 copies of chromosome 21.
When this gamete fertilizes with another gamete, it results in the formation of a zygote with 47 chromosomes, that is, 46 chromosomes + extra copy of chromosome 21.
