Answer:
125 molecules
Explanation:
Between two amino acids , one water molecule is eliminated and a peptide bond is formed. When 250 amino acids are joined to form a polypeptide , 125 molecules of water will be removed.
That is, 250/2=125
Answer:
A). dissolved into other substances
Explanation:
Process of elimination-
B) loss of protons-mechanical reaction
D) reorganized into different substances-physical reaction
Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.
Fat; they store twice as much energy per gram
Answer: Option A) Double-stranded DNA
Explanation:
First, the presence of thymine infers that the genome is DNA.
Then, to determine whether it is single or double stranded, we check if the sum of all nitrogenous bases is equal to 100%
A + C + G + T = 100%
28% + 35% + 20% + 17% = 100%
Since all bases makes 100%, we can conclude that the genome is a double stranded DNA
