Answer:
A. Mutations change the nucleotide sequence of the gene, resulting in a different arrangement of amino acids.
Explanation:
Mutations alter the sequence of nucleotides in a molecule of DNA. DNA is used to create mRNA, which is used to create a chain of amino acids that make a protein. If the mutation changes the sequence of DNA, then the sequence of amino acids and the final protein will be different.
This can affect its structure and function. If the protein is a cell surface protein, and its structure is significantly altered, antibodies may no longer recognise and bind to the protein.
Answer:
B. Human disturbances
Explanation:
Human disturbances is an example of density independent factor. These human disturbances are actually caused by human activities that are carried out by people. These disturbances result to pollution, destruction of habitats, depletion of resources, urbanization, etc.
Density-independent factors are known to be the factors that influences the birth and death rate of the population. This happens regardless of the population density i.e it does not depend on population.
Some of these density-independent factors are also food or nutrient limitation, climate extremes, pollutants in the environment, etc.
