Explanation:
The right answer is B. controlling the flow of blood to the skin
When the body temperature is below the set point, the hypothalamus activates several thermogenesis mechanisms:
* Vasoconstriction on the vessels near th skin by the sympathetic nervous system to reduce thermal exchanges between the skin and the surrounding environment.
* And increase in heat production:
-by muscular activity:
-by the metabolism:
Answer:
If the sequence of one strand on DNA is CTA GCT CCA, the
complementary strand is GAT CGA GGT.
Explanation:
The DNA molecule has four nitrogenous bases in its structure, two purines —adenine and guanine— and two pyrimidines, cytosine and thymine.
The two DNA strands are linked by hydrogen bonds established between their complementary nitrogenous bases, where a purine is complemented by a pyrimidine.
In the case of DNA, adenine is complemented by thymine and cytosine is complemented by guanine:
<em>A=T</em>
<em>C≡G</em>
In the sequence belonging to a DNA strand CTA GCT CCA, the strand that is complementary would be GAT CGA GGT.
Answer:
The marine industries affected the marine life and ocean water in many ways. When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean's pH drops. In the past two hundred years alone, ocean water has become 30 percent more acidic and faster than any known change in ocean chemistry in the last million years.
