Answer:
A. Humus forms from fallen leaves, dead wood, and other dead organic matter.
Option are the following;
A. Humus forms from fallen leaves, dead wood, and other dead organic matter.
B. Tree roots break rocks into humus as they grow.
C. Cold winter weather preserves humus in the soil.
D. Dry conditions allow humus to form
Explanation:
Humus is a type of organic matter which is formed due to the decomposition of plant parts and leaves by the action of decomposers such as bacteria and fungi. The soil of the temperate forest is often rich in humus because when the leaves falls from the trees when get older, these leaves mixes with the soil and due to the action of microorganisms such as bacteria and fungi. These microbes feed on these leaves and releases nitrogenous material which is used by the plants for making amino acid and enzymes etc.

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.
