d. Spiral-shaped bacteria are generally aerobic, but a subset of the group uses anaerobic respiration.

Which statement best describes respiration in spiral-shaped bacteria?

Spiral-shaped bacteria are generally aerobic, but a subset of the group uses anaerobic respiration.

Explanation:

Bacteria have two ways of making energy: aerobic respiration and anaerobic respiration.

Some bacteria are obligate aerobes that they require oxygen for aerobic respiration. Others can switch to anaerobic methods if oxygen is not present. Examples of aerobic bacteria are Nocardia sp., Psuedomonas aeruginosa, Mycobacterium tuberculosis, and Bacillus .

Spirilla are Gram-negative bacteria with a helical or spiral shape.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
