Answer:
b
Explanation:
earth's ocean did grew higher over time because o rainfall for the last 20 years!
Answer:
None of the above.
Explanation:
GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.
The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.
Thus, the correct answer is option (d).
Answer:
The byproducts cause the released of high concentration in the fermentation acids and the deceases in the level pf PH. It basically leads to inhibition of the growth of many bacteria. The toxicity at low PH value of the fermentation acids traditionally defined the uncoupling mechanisms. The fermentation acid are resistant bacteria with low PH and It able to generated the ATP and groe the low PH intracellular.
<h3>
Answer: Hydrophobic, Hydrophilic (Option 2)</h3>
Explanation:
The tails of the cell membrane are __hydrophobic__ while the phosphate heads are __hydrophilic__.
I hope the following image helps to further explain the answer.
Answer:
a) the oxidizing agent.
Explanation:
In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.
