Answer:
50%
Explanation:
DNA replication is a semi-conservative process. It means that after DNA replication, the newly formed DNA molecules have one parental strand and one newly formed strand. The cells in the experiment have DNA with 15N. After one round of DNA replication, each DNA molecule would have one parental DNA strand with 15N and one newly formed DNA strand with 14N.
However, after the second round of DNA replication, each hybrid DNA with strand having 15N and the other with 14N would be unwound. The parental heavy DNA strands would be present in the 50% of the newly formed DNA while the rest 50% of DNA molecules would have both strands with 14N (both light strands).

The item produced when a yeast cell undergoes fermentation is ethyl alcohol. The correct answer is A.
Answer:
Saturated fats/ solid fats
Explanation:
Vegetable oils amongst other unsaturated oils are liquids at room temperature while saturated oils are solids or spreadable at room temperature.
Industrially, vegetable oils are hydrogenated; hydrogenation is the process of adding hydrogen to an unsaturated compound to make it saturated. This then makes these hydrogenated vegetable oil, saturated which makes them solids as earlier stated, they are also called cis - fatty acids.
Trans - fatty acids as well are also unsaturated oils which are hydrogenated industrially to give saturated fatty acids which are called artificial tran-fats. They are found in most commonly found in baked and fried goods.
