Based on the 20 amino acids found in proteins, there are 6840 possible variations in a polymer composed of just three amino acids.
<h3>What are amino acids?</h3>
Amino acids are the molecules from which protein molecules are made from.
There are 20 common amino acids from which protein molecules are built up from.
The amino acids are joined one to another in the protein by peptide bonds.
In a polymer composed of three amino acids, the possible variations are calculated by permutation.
The possible variations are 20 permutation 3.
nPr = n!/(n - r)!
where n = 20 r = 3
nPr = 20!/(20 - 3)!
nPr = 6840
Therefore, there are 6840 possible variations in a polymer composed of just three amino acids.

Answer:
this answer is D because it's independent variable
Answer:
The harvesting of energy from ATP to do cellular work
Explanation:
Answer:
The inner membrane of a mitochondria are made up of phosphoslipid bilayer just like all membranes surrounding animal cells. The bilayer is made up of hydrophobic tails which point inwards, and the hydrophilic layer pointing outwards away from the inner fluid layer. Thus entry of substances into and out of the cells cytoplasm are well regulated.
Layers of protein are embedded in the membrane to transport electron spitted from Hydrogen atoms deposited by FADH2 and NADH2 into the matrix. This set up gradient for the transport of electrons in chains called Electron Transport Chain.
The adaptive features of of inner membrane is its large surfaces areas to volume ratio to accommodate enough hydrogen ions / protons pumped by PMF, needed to set up electrochemical gradient for energy used by ATPase Synthase for ATPs production.
Enzymes are proteins. therefore the smaller units are amino Acids units are linked by polypeptides chains. Basically carboxyl group,Amino group, Hydrogen and R-group( which determines the nature of Amino Acids) are the basic functional group of Amino Acids.
Enzymes are globular proteins formed from confrontational change on the amino acids moiety ,
They are organic catalyst which speed up the rates of biochemical reactions in living organism.

Answer:
B. Molecular Systematics
Explanation:
First, let's review a few definitions. DNA, deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the side pieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine: the genetic information of DNA is encoded in a sequence of the bases and transcribed as the strands unwind and replicate. Molecular systematics is a scientific discipline that uses nucleic acids or other molecules to infer. evolutionary relationships between different species.
