The substance that is coded for by a length of DNA is base. The correct option is A.
<h3>What is a base?</h3>
Nucleobases, also known as nitrogenous bases or simply bases, are nitrogen-containing biological compounds that form nucleosides, which are then components of nucleotides, all of which are the basic building blocks of nucleic acids.
The complete question is attached.

Answer:
Temperature is one factor that can affect the rate of diffusion. Diffusion occurs faster in warmer temperatures, and occurs slowly in cooler temperatures.
For lactic acid fermentation, the correct options are:
- pyruvate
- hydrogen
- NADH
- lactic acid
- Lactic acid
- pyruvate
- mitochondria
For ethanol fermentation, the correct options are:
- pyruvate
- CO₂
- acetyl CoA
- acetyl CoA
- acetaldehyde
- Acetaldehyde
- hydrogen
- NADH
- ethanol
<h3>What is a anaerobic respiration?</h3>
Anaerobic respiration is respiration which occurs in the absence of oxygen.
Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.
Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.
In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.
On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.
After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.
In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.

Answer:
the answer is a. it is the change in heritable traits in living populations over successive generations
Explanation:
It is produced industrially by fermentation using yeast or bacteria. Marmite's defining ingredient is made from brewer's yeast heated to create glutamic acid, which is used by farmers to increase plant growth and boost crop yields.
