Answer:
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
Breathing in air pollutants can irritate your airways. It may cause shortness of breath, coughing, wheezing, asthma episodes and chest pain. Overtime, exposure to air pollution puts you at risk for lung cancer, heart attack/strokes, etc. Some people are more at risks from others though

Explanation:
The electrician just cannot replace any piece of wire to fuse because the ceramic that is used in case of fuse has a wire attached in it.
This wire is of low resistance so that when there is higher voltage the wire just cannot tolerate the high voltage and wire breaks down.
Any wire just cannot be replace by the fuse because the there are some calculations which has to be made.
The wire if used should be of low resistance and more properties then only it is eligible to be replaced by fuse.

Answer:
The correct answer will be option-about 174 base pairs of DNA are wrapped around an octamer of histone proteins.
Explanation:
A nucleosome is the fundamental unit of the chromatin thread polymer of DNA which is made up of a nucleosome core. The nucleosome core is composed of histone proteins H2A, H2B, H3, and H4 arranged in two copies forming an "octamer structure of proteins".
About 174 bp of DNA wraps around this nucleosome which is connected to other nucleosomes through 160 to 240 bp linker DNA.
Thus, the selected option is the correct answer.
