These had no leaves or roots, instead they had green photosynthetic stems which served as both anchors in the ground and photosynthetic surface.
Answer: Peptide bond
Explanation: A peptide bond is the covalent chemical bond bond that holds together two amino acids which occurs when the carboxylic group of one molecule reacts with the amino group of the other molecule, linking the two molecules and releasing a water molecule catalyzed by peptidyl transferase, an RNA-based enzyme integrated into the growing chain.
In the elongation stage ie when Long chain polypeptides are forming , peptide bonds are formed by linking many amino acids to each other. These peptide bonds of amino acids are relatively unstable, and can break spontaneously in a slow process as can be seen especially in enzymes of living organisms in the making and breaking of bonds.
Answer: (A) the time that two species have been evolving independently.
Explanation: The molecular clock is figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when<u> two or more life forms.</u>
Answer:
A critical function of proteins is their activity as enzymes, which are needed to catalyze almost all biological reactions.
Answer: Because if we assume the cannibal has to fight to the death then the stronger will win and the weaker will die off.
