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.

7.<br> Why is most bioluminescence blue in color?
Temka [501]

Answer:

Bioluminescence is light produced by an organism using a chemical reaction. While usually blue in color, because this is the light that travels best through the water, bioluminescence can range from nearly violet to green yellow and very occasionally red.

At higher doses, __________ causes slowed or stopped breathing and can cause organ failure and gangrene.
klasskru [66]

The correct answer is Oxycodone.

Oxycodone refers to a drug, which is generally prescribed in certain cases to treat severe pain. At lower doses, it leads to fatigue, memory loss, headache, itching, anxiety, and constriction of the pupil. At higher doses, Oxycodone causes lowered heart rate, slowed or stopped breathing that may eventually lead to unconsciousness and death.

In addition, it can also result in inhibition of blood flowing in specific regions of the circulatory system. This can eventually result in organ failure, loss of muscle control, and gangrene.
