The right answer is B) NADH and FADH2.
NADH, FADH2 are molecules involved in the Krebs cycle, they carry electrons and H + protons.
NAD is involved in metabolism as an electron carrier in oxidation-reduction reactions, NAD + as an oxidant and NADH as a reducing agent.
Flavin adenine dinucleotide (FAD) is an oxidation-reduction cofactor derived from riboflavin (vitamin B2). It is associated with the enzymes of the class of oxido-reductases to which it is linked by a covalent bond: it is a prosthetic group.
The redox couple is: FAD ==> FADH.
The correct answer is : Non-native species is the example that affects biodiversity.
These species can be an agent of unacceptable economic, biological or social aftermath.
However, these species still provides in the regional biodiversity like biotic interactions and species richness and ecosystem services.
Answer:
none of these codons
Explanation:
In order for mutation to occur to form methionine codon from an isoleucine codon, position 3 must be changed to a G, giving AUG. A secind mutation would then be required at a second site in the AUG codon. since the isoleucine codons, AUA, AUC and AUU does not have a G at position 3, a true reversion can't occur without mutating the position 3 again.
DNA polymerase is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Polymers are Nucleic Acid, which are large molecules made up of smaller, repeating units that are chemically connected to one another.
Answer:
they are found in intertidal zones
