Answer:
D. Because science only uses facts that are proven 100% true through the use of variables.
Explanation:
All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is proven 100% true through the use of variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.
Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of variables.
Hope it helps!
Answer:
The process of cellular respiration, which converts simple sugars such as glucose into CO2 and water, is an example of <u>a catabolic pathway.</u>

Answer:
DNA ligase
Explanation:
<em>The biochemist must have left out DNA ligase enzyme.</em>
<u>The DNA ligase enzyme is able to catalyze the formation of phosphodiester bonds and as such, capable of joining strands of DNA together to form a single strand.</u>
The numerous DNA segments of a few nucleotides long observed by the biochemist must have been the replicated product of the lagging DNA strand. The lagging strand is replicated discontinuously in short strands because the DNA polymerase enzyme can only elongate primers in 5' to 3' direction. The short segments are known as Okazaki segments and are usually joined together to form a whole strand by the DNA ligase enzyme.
Hence, the missing component is the DNA ligase.
