Answer:

The answer is A.Primary succession

Explanation:

Primary succession is an ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).

HELPPPPP<br> how could changing one mRNA codon change a protein?
Alex_Xolod [135]

Answer:

the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.

The mutation rate is the probability of a single gene mutating in an offspring bug.
Ilya [14]

Answer:

True

Explanation:

A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/<em>locus</em>/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations <em>per</em> round of replication, <em>per</em> gamete, <em>per</em> cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of <em>de novo</em> mutations per nucleotide <em>per</em> generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ <em>per </em>gene <em>per</em> generation.
