It is c.a decrease of gravity!!
Answer: B
Explanation:
The question wants to know what the expression is directly dependent on.
The sequence of genetic expression goes like this:
DNA -> RNA -> protein
If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.
The Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.
Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.
Answer:
A: Anabolic pathways build molecules, require energy and are endergonic
Explanation:
Anabolism and catabolism are the two important process of metabolism - a process through which cells get energy to drive various processes within the body and get rid of toxic wastes.
Anabolic and catabolic reactions can be described as opposing sides of the same coin. While anabolism refers to the various reactions that build up molecules within the cell, catabolism has to do with the breakdown of big or complex molecules into smaller ones.
Both processes involves energy. Anabolic reactions require energy to drive the building up process and therefore referred to as endergonic reactions. On the other hand, catabolic reactions liberate energy during the breaking down of complex molecules and therefore referred to exergonic reactions.
A good example of anabolic reaction is photosynthesis which involves the building up of carbohydrate (glucose) using carbon-dioxide, water molecule and energy while a good example of catabolic reaction is respiration which involves the breakdown of carbohydrates into carbon-dioxide, water molecules and the release of energy.
Hence, the only correct option is A.
ADP (adenosine diphosphate)
