Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. ... The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.
Explanation:
Answer:
A) few B) 100% c) 100%
Explanation:
Muscle responds a stimulus which is capable of generating action potential. Muscle response is in a way of "ALL or NONE". Muscle response to greater stimulus by recruiting more muscle fibers.
A) At threshold there would be only a small proportion of muscle is contracting.
B) At maximal stimulus the maximum number (100%) of recruitable fibers are contrating.
C) The number of recruitable fibers can't increase above maximal stimulus because already the maximum number of recruitable fibers are contracting.
Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.
