The process that destroys or removes all microorganisms and microbial forms including bacterial endospores is called

A. Autotroph: Autotrophs are organisms that use carbon dioxide (CO₂) as their primary carbon source, converting it into organic molecules through processes like photosynthesis or chemosynthesis. They are capable of synthesizing all the carbon compounds they need for growth, making them independent of other organisms for carbon.

B. Heterotroph: Heterotrophs obtain carbon by consuming organic compounds produced by other organisms. They cannot fix CO₂ directly and rely on autotrophs or other heterotrophs for their carbon supply, which is why they are considered consumers rather than primary producers.

C. Parasite: Parasites are organisms that live on or within a host organism, deriving nutrients at the host’s expense. While many parasites are heterotrophic, being parasitic describes their lifestyle rather than their carbon source.

A. nucleotide: A nucleotide is the basic structural unit of DNA and RNA, consisting of a sugar, phosphate group, and nitrogenous base. While nucleotides make up the DNA sequence, a group of three bases does not code for a single nucleotide but rather for an amino acid.

B. amino acid: A codon, composed of three consecutive nucleotide bases in DNA or RNA, specifies a single amino acid during protein synthesis. For example, the DNA triplet ATG codes for the amino acid methionine. This triplet code is universal and ensures accurate translation from genetic information to functional proteins.

C. purine: Purines, such as adenine and guanine, are types of nitrogenous bases. They are part of nucleotides, but a triplet of bases does not directly correspond to a single purine; instead, codons dictate amino acids.

D. protein: Proteins are composed of long chains of amino acids. While codons ultimately determine the sequence of amino acids that form a protein, each codon specifies only one amino acid, not an entire protein.
