<span>A. A nucleic acid has alternating base pairs. A protein has alternating peptides.</span>
Answer:
Mitosis only
Explanation:
Mitosis and meiosis are both types of cell division. Mitosis allows cells to proliferate for growth and repair. So this is how skin cells form new cells.
Meiosis is a type of cell division specific to reproduction. It forms the gametes, which are the egg and sperm. It generates haploid cells that fuse via fertilization to create a zygote.
Answer:
The correct answer is D) Rate of fermentation.
Explanation:
Carbohydrates are fermented by yeast to form alcohol by alcoholic fermentation.
Now if the effects of different carbohydrate molecules are tested on yeast then the yeast will ferment different sugar molecules at different rate.
As a result the rate of fermentation will be the independent variable of the experiment.
C
<em>[From ck12.org] </em><u>"An organ can be part of more than one organ system. For example, the ovaries produce hormones, which makes them a part of the endocrine system; the ovaries also make eggs, which makes them a part of the reproductive system as well."</u>
<span>The third option:</span><span>This statement is true because every step in protein synthesis requires enzymes, which are nothing but proteins.</span><span>
</span>I mean if you look at rRNA which is needed to make polypeptide chains, it is 2/3 protein, and then the helices, ss binding proteins, DNA polymerase and everything in transcription is protein.
So that last option/ third option is the best
