Which of the following is NOT necessary for respiration?

Biology
1 answer:
nekit [7.7K]3 years ago
5 0

The right answer is surprisingly E.

Quinones, flavoproteins, cytochrome c, and electrons are important elements, essential for the respiratory chain.

Oxygen in respiration plays a role of final acceptor of electrons (and turns into H2O), but there are other final acceptors of electron transport depending on the species (nitrates for Pseudomonas, Sulphites for Clostridium ...). This allows us to classify respiration in two: aerobic respiration (with oxygen) and anaerobic respiration (without oxygen but with another electron end acceptor).

9) Genetic variation is the source for evolution. Without a variety of phenotypes, there would be no differential survival upon
Firlakuza [10]

The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion. The correct options are D and E.

<h3>What is genetic variation?</h3>

The presence of differences in gene sequences between individual organisms of a species is referred to as genetic variation. It allows for natural selection, which is one of the primary forces driving life's evolution.

The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion.

Thus, the correct options are D and E.

The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration
Hitman42 [59]

Answer:

The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.

Explanation:

The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.

A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.
