Answer:
The level of compaction in Eukaryotes from naked DNA to the most compact is:
d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome
Explanation:
As we know that the
- Diameter of DNA is 2 nm.
- Diameter of nucleosome is 11 nm.
- Diameter of solenoid is 30 nm.
- Diameter of looped chromation is 300 nm
- Diameter of meta-phase chromosome is 1400 nm
All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.

Explanation: I did it on Edge 2020 and it was correct.
Answer:
There will be few if any complications.
Explanation:
Just took the unit test review
Answer:
The correct answer will be option- adhere to cell surfaces.
Explanation:
The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.
The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.
Thus, option- adhere to cell surfaces is the correct answer.
