Most fungi grow best at ph
a. 1
b. 5
c. 7
d. 9
e. 14

The correct answer is b. 5

Explanation:

Fungus are more likely to grow at low pH and so they love acidic environment to grow and live. The organisms who love to grow in an acidic environment are called acidophiles.

The optimum pH at which fungi like to grow is between 5 to 6. Fungi growth condition is different from most of the microorganisms because micro-organisms tend to grow well at and above pH 7. So bacteria basically like alkaline environment to live.

When pH decreases from 7 to 5 the growth of fungus in increased by many folds which shows that fungus like to grow at low pH. Therefore the correct answer is b. 5

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
