Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.
Using this calcification rate,
30 = 20 * 1 * days
days = 1.5
The deposition will require 1.5 days.

Answer: B
Explanation:
During polymerization of nucleotides to form nucleic acids, the hydroxyl group on the phosphate group attaches to the 3’ carbon of a sugar of one nucleotide to form an ester bond to the phosphate of another nucleotide. The reaction forms a phosphodiester linkage and eliminates a water molecule.
The DNA strands generally runs from 5 prime to 3 prime direction.
Answer:
Hormones act as first messenger but not as second messengers.
Explanation:
Second messenger act as signaling molecule which are secreted in response to various biological signals generated by first messenger such as hormones,neurotransmitters etc.Second messengers include various bioactive molecules such as cyclic AMP(cAMP),cyclic GMP(cGMP),inositol triphosphate(IP3),diacylglycerol(DAG),calcium ions(Ca2+) etc.
Hormones are extracellular signaling molecules whereas second messengers are intracellular signaling molecules.
Answer:
Explanation:
The population would decrease I believe because that means that if there is more organism that an environment can handle that means there won't be enough resources for all of the organism like food that means the population will slowly die off.
