Answer:
Partial hydrogenation
Explanation:
Vegetable oils naturally contain cis fatty acids. These fatty acids have double bonds and the two H atoms are on the same side of bond, producing a kink in the structure.
Cis fatty acids are converted into trans fatty acids by the process of partial hydrogenation or vegetable shortening. Hydrogen is added to convert some of the double bonds into single bonds but all double bonds are not removed. However, the cis double bonds end up getting converted to trans double bonds. H atoms are now on the opposite sides of the double bond. This arrangement makes the kink disappear from the structure hence trans fat is structurally similar to saturated animal fat. It increases the longevity of fats and makes it solid at room temperature but also has many side effects like increasing bad LDL cholesterol in blood.

Explanation:
Fertilization refers to the process of two gametes of opposite sex uniting (option C).
<h3>What is fertilization?</h3>
Fertilization is the process whereby the male gamete unites with the female gamete to form a zygote.
In sexually reproducing organisms, the male organism of a species produces a gamete called sperm cell while the female organism produces egg or ova.
Therefore, it can be said that fertilization refers to the process of two gametes of opposite sex (male and female) uniting.

Answer:
To separate DNA using agarose gel electrophoresis, the DNA is loaded into pre-cast wells in the gel and a current applied.
Explanation:
The phosphate backbone of the DNA (and RNA) molecule is negatively charged, therefore when placed in an electric field, DNA fragments will migrate to the positively charged anode.
