The most important factor that one should determine in safe
vessel speed on any given day is to be made aware of the conditions in terms of
visibility. Example of these would be the darkness, rain, mist or fog. Another
thing is to check weather conditions and the currents of the water to determine
speed for your boat as you head to the water.
Answer:
The human body comprises approximately 70% water by weight. Water is located inside and outside of cells, and it can carry nutrients into and around cells in addition to carrying wastes away from cells. ... The membrane is thin enough for water to pass through, but it is not thin enough for the solute to pass.

The answer to your question is B<span />
Answer:
C) Three hydrogen bonds will form with guanine.
Explanation:
Generally the DNA molecule is made up of Purines bases of Adenine and Guanine,and Pyrimidine of Cytosine and Guanine.However,RNA contains a different pyrimidine of Uracil.Thus the pairing is A-U am C-G.The uracil replaces Thymine.
The structure above is a Pyrimidine,because it is made up of single ring structure(an heterocylclic aromatic structure) compare to double structure of purines. Heterocyclic means it is ring form.Aromatic means it has resonance bonds which shift with the rings for stability.
It is also contains of two substitutes at position 4 of the ring structure (amineNH2) and at 2 which is the Keto group(=0).Therefore the structure is Cytosine.
In RNA structure the Cytosine pair with the three hydrogen bonds with guanine,while Adenine pair with Uracil.This ensures stability of the RNA structure.
