Mila [183]

Answer:

True

Explanation:

Facultative anaerobes are bacteria who used to grow in the aerobic condition but when oxygen becomes deficient they can switch to anaerobic mode and obtain energy through fermentation. So facultative anaerobe normally lives in aerobic condition but can survive in anaerobic conditions too.

So as facultative anaerobes normally grows in aerobic condition they grow well in incubator shelf but in anaerobic condition like anaerobic jar or in a candle jar they will show moderate growth because it is not the ideal condition for them to grow. Therefore the statement is true.

The tertiary structure of a polypeptide is the Select one:_________
Rufina [12.5K]

Answer:

The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.

Explanation:

A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to  stabilize many polypeptides.

Which gas is used by plants for photosynthesis and released by all living things during respiration?
Tju [1.3M]
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose
