Answer: option D) II, III, and IV only
II. Mutations can have a positive effect on an individual.
III. Mutations can have no effect on an individual.
IV. Mutations usually have a negative effect on an individual.
Explanation:
The effects of mutation on the fitness of an organism include:
II) a mutation can be positive once it increases the fitness of the organism e.g the emergence of the malaria-resistant sickle cell hemoglobin gene (AS) instead of the AA gene that is susceptible to malaria attack.
III) a mutation that occurs in an amino acid that results in the use of a different, but chemically similar amino acid e.g a change from AAA to AGA will encode arginine, a chemically similar molecule to the intended lysine. This is called a NEUTRAL MUTATION - and it has no effect on the organism
IV) In general, mutations usually are deleterious - having negative effects - and reducing the fitness of organism. e.g Sickle cell anemia and hemophilia are due to mutations

Answer:
Decomposition
Explanation:
The "Carbon Cycle" consists of<u> four processes</u> and these are: <em>Photosynthesis, Decomposition, Respiration and Combustion</em>.
After the process of photosynthesis, the animals will consume the plants and then will die and so will the plants after many years later. They will decompose and turn into fossil fuels, which are <em>organic materials.</em> The organic materials will then be decomposed by <em>Actinobacteria</em> into <em>inorganic materials. </em>These stays into the soil and allows the growth of plants once more. Then, the <em>Respiration </em>process follows.
