Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.
Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, <em>crossing over</em> or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/<em>loci</em> located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/<em>loci</em> (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.
The answer is A, as most sewage treatment plants use bacteria to break down and remove nutrients. The main water pollution problem caused by sewage effluent is eutrophication, related to the release of nutrients into rivers and lakes. Nutrients such as nitrogen and phosphorus ions result in high algal growth. Some algal blooms release toxins, and algal blooms also disrupt the natural dissolved oxygen concentration cycles. Fish kills are often because eutrophication has resulted in anoxic conditions.
Anyway, wastewater treatment plants utilise bacteria to facilitate nitrification or denitrification, which removes ammonia and nitrates/nitrites, respectively.
That would be I, II, and III
I and II will cause a frame shift mutations.
II can cause horrible effects if the substituted base codes for a stop codon.
The hydrocarbons' surface.
Because the covalent link that exists between hydrocarbon surfaces is different from the surfaces to which the salamander can cling, the salamander has difficulties adhering to these surfaces.
The hydrogen bond is the bond that exists between hydrogen and a bigger molecule like nitrogen or oxygen, whereas a covalent bond includes sharing electrons.
<h3>What Are Hydrocarbons and What Do They Do?</h3>
Crude oil, natural gas, and coal are all examples of hydrocarbons, which are organic compounds made of hydrogen and carbon. The world's primary energy source and a highly flammable substance, hydrocarbons. Petrol, jet fuel, propane, kerosene, and diesel are only a few of its uses.
