Answer:
The idea around genetic have changed.
Answer:
oxygen because that's one of the substance that plants produce.
You can also do this by the process of elimination. Knowing that atrazine impedes the production of substances in plants, we know that it can't be DNA and Phospholipid. Carbon Dioxide is used by plant, not produced; thus, oxygen is the answer.
C. An increase in human population
Explanation:
Template: T, A, C, G
Pairing: T- A, A-T, C-G, G-C
Answer: adenine, thymine, guanine, cytosine
Further explanation:
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.
Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.
DNA stores all of an organism’s genetic information. Its molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule ;
- cytosine and thymine are formed from pyrimidines- N at position 1 and 3 of a fused ring;
- Guanine and adenine are formed from organic compounds called purines (pyramidines fused to another organic ring of imidazole)
- Each base pair contains a purine and pyrimidine joined via hydrogen bonding e.g. A-T & G-C and are called base complements.
In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

Answer:
C. Joining of self-replication molecules into protocells.
Explanation:
For the origin of life, at least three conditions are needed.
- there must have been a supply of replicators, that is, self-replicating molecules.
- copying of these replicators must have been subject to error through mutation.
- the system of replicators must have required a continuous supply of free energy and partial isolation from the general environment.
The radiation received from the sun on the early earth must have fulfilled the requirement of mutation. The mutation is necessary for bringing variation in the genetic material thus driving evolution. To protect the self-replicating molecules from the external environment and to keep them together, the molecules must have been enclosed in a membrane barrier, which should be selectively semipermeable, to facilitate the exchange of molecules.
