Answer:

A:Lack of rainfall

Explanation:

In Ecology, certain factors affect the population of species in an ecosystem. These limiting factors can either be density dependent or density independent. Based on the question, density independent limiting factors are those factors that affect population size of species irrespective of their density in an ecosystem.

The effect of density independent factors is not dependent on the size of the population, so it tends to affect process limit all populations in the ecosystem. Density independent factors are usually environmental-related e.g natural disasters, lack of rainfall as mentioned in the options.

Lack of rainfall in a particular ecosystem will affect all population species irrespective of how dense they are. Hence, it is a density independent limiting factor.

What results from the addition or deletion of nucleotides in any number except a multiple of 3?
eimsori [14]
Addition or deletion of nucleotides in any number besides 3 results in a "frame-shift mutation."
This is because every 3 nucleotides of DNA/mRNA exons codes for a single amino acid in the synthesis of a protein. This triplet codon theory means that if 3 nucleotides are added or deleted then an amino acid will be added or lost, but subsequent codons and amino acids will still be read correctly.
However, if any number of nucleotides other than 3 are added or removed, then the codons following the mutation will be out of "sync," in terms of the reading order.
Hence it is called a frame-shift mutation because it shift the reading frame when translating nucleic acids into proteins. Frame shifts will lead to the wrong amino acids being adding in the wrong order for the rest of the code after the mutation.
