The term monomer refers to:
a unit made up of several atoms
Explanation:
A monomer is a molecule that "can support polymerization whereby providing constitutional units to the fundamental structure of a macromolecule". Large quantities of monomers combine to form polymers in a method called polymerization.

The missing part of this question is as follow:
Redi placed pieces of meat in several jars. He divided the jars into two groups. He covered the first group of jars with fine cloth. He left the second group of jars uncovered. Redi observed the jars for several days. He saw files on the cloth of the covered jars, and he saw files laying eggs on the meat in the uncovered jars. Maggots appeared only on the meat in the group of jars left uncovered
Answer:
The correct answer is - b. Covering one jar and leaving the other uncovered.
Explanation:
Variable or the factors in an experiment that is subject to change or that affects the particular experiment. In the experiment of F. Redi, he used two groups of jars one covered with fine cloth and the other open and exposed to the environment.
There is a change in the result of the experiment of Redi due to these variables as the jar that was covered has no maggots while maggots appeared in open jar.
If the base sequence on a DNA molecule is ATC then UAG will be the mRNA sequence.
The four nucleotides found in mRNA — A, U, G, and C — can be combined in a total of 64 different ways because codons are three-letter structures. These 64 codons are made up of 61 amino acid codons and three stop signal codons, which signal the completion of protein synthesis.
A codon is a specific sequence of nucleotides on an mRNA that denotes either a stop signal during protein translation or a specific amino acid. A nucleobase (also known as base), a sugar, and a phosphate group make up a nucleotide.

The discoverers of DNA were not James D Watson and Francis Crick. They are the first scientist to formulate an accurate description of the DNA’s (deoxyribonucleic acid) complex , double-helical structure. They discovered that base pairing nucleotides must be; adenine and thymine; and cytosine and guanine. These base pairs are held together by a hydrogen bond, atype of chemical reaction that s easy to break and easy to reform. The statement is “DNA is a double helix made of two strands linked together with hydrogen bonds.”
b. exoskeleton
c. labium
d. ocelli
