Darwin reasoned that natural selection had been the reason for organisms matching so well to their environments.
They all breathe oxygen
Their body is full of water
Hope this helped :D
Answer:
lactic acid from anaerobic respiration
Explanation:
<span>Trypsin is an enzyme that is present in pancreatic juice. It helps to digest proteins and break them down into something that can be absorbed by the body. It is an enzyme that hydrolyzes(1)peptide
bonds into smaller sub-units called (2)oligopeptides and dipeptides, which are further hydrolized into amino acids to make them available for absorption into the blood stream. </span>
<span>Steapsin is also an enzyme in pancreatic juice or is a pancreatic lipase called triacylglycerol lipase. It catalyzes the breakdown of fats. It is an enzyme that hydrolyzes (3)fats into smaller sub-units
called (4)fatty acids & (5)glycerol. Phenol red is a pH indicator that can determine the presence of acids. It is a color indicator that
turns turns (6)yellow in the
presence of acid.</span>

The best answer would be:
A membrane bound nucleus
<u>Here is more about the question:</u>
There are three domains in the classification of organisms and they are Eubacteria, Archaea, and Eukarya. What makes Eukarya different from the other two is the presence of a nucleus in the cells. Among the remaining two, Archaea is more closely related to Eukarya than Eubacteria.
