Answer: C. The sound from the bang echoes though the universe
Explanation:
Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.
Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.
There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.
ANOVA is used to test the association of categorical variable with the numeric variable, so it won’t be an appropriate use in the above condition.
Explanation:
ANOVA test include the testing of groups and their difference to accept or reject the hypothesis of a survey. It is applied on group of people having same condition and trying different therapies to see which is better. It can also be used to apply on two tests performed by one group.
But here in the above-mentioned condition, one test is being observed by people having different conditions. So, the ANOVA test wouldn’t be appropriate here.
Answer:
The active smokers and those getting exposed, that is, passive smokers are at enhanced threat of bacterial infections. Getting exposed to tobacco smoke enhances vulnerability to respiratory tract infections, comprising pneumonia, tuberculosis, and Legionnaires disease.
Smoking compromises the anti-bacterial activities of leukocytes incorporating monocytes, neutrophils, B cells, and T cells, thus, demonstrating the mechanism for enhanced risk of infections.
