Answer:
Solid Liquid gas and plasma
Explanation:
These are characteristics of matter
<span>Neutral mutations are neither harmful nor beneficial.
Therefore, they are invisible to natural selection. (Since they neither improve nor worsen one individual's chances of survival and reproduction over another.)
However neutral mutations can still spread into the population by just random replications and matings. This is called genetic drift.
In other words, they are 'silent'. They are mutations that exist and propagate in populations, but seem to have no effect at all.
The reason they can become important to evolution is that a day can come when they *do* have an effect. In other words, even though an individual mutation may have no immediate effect on survival or reproduction, a *combination* of neutral mutations may provide some new benefit or harm ... at which point natural selection *will* act on that combination.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
Evolution is all about the
process of inheriting characteristics within a population change over
generation.
Only inherited traits
differences that can be passed on are acted upon evolution.
<span>In the study, the humans
select desirable traits that can be passed from one generation to another.</span>
D. is correct: Koalas evolved after trout.
(A is false, B is also false bc amoeba are unicellular, C is false too, they are definitely not in the same class)
Answer:
Site-directed mutagenesis
Explanation:
Site-directed mutagenesis (SDM) is a technique widely used in molecular biology in order to generate site-specific, targeted changes in the DNA sequence of a gene of interest. The SDM protocol consists of using a complementary oligonucleotide (primer) that contains the desired mutation, which hybridizes to the target DNA sequence and thus can trigger the desired mutation. Nowadays, the versatile CRISPR-Cas9 genome editing system is the most used technique to produce targeted mutations in any gene of interest.
