Agata [3.3K]

Answer: D. The fungus and bacteria organisms are obtaining the energy they need by decomposing organic matter like dead trees and old apples.

Fungi is the primary decomposer of biological waste in forest ecosystem. Fungi grows on the branching network of hyphae which provide it more penetration potential towards the litter. Wood decaying fungi has enzymes required for decomposition of lignin, a chemical substance found in wood. Fungi decompose organic matter by releasing enzymes which breaks down the decaying matter, after that they absorb the nutrients in the decaying material. The left residue in the organic matter includes sugars and amino acids are degraded and decomposed by the bacteria.

A DNA molecule with a total of 1500 nucleotides has 300 cytosines. How many thymines does the DNA molecule have?
Sergeu [11.5K]

The DNA molecules will have 450 thymines if a DNA molecule has a total of 1500nucleotides

A DNA molecule also known as deoxyribonucleic acid is made up of a double helix.

The DNA molecule with a total of 1500 nucleotides will contain 750 cytosine and Thymines and 750 guanines and adenine.

Hence we can have the expression:

C + T = 750

If there are 300 cytosines, hence;

300 + T = 750

T = 750 - 300

T = 450

This shows that the DNA molecules will have 450 thymines
