Sparky and Bailey are bacteria that represent two extremes of antibiotic sensitivity. Sparky cannot survive any exposure to peni

cillin at all, while Bailey can survive exposure to twice the concentration of penicillin used to treat most infections. In a healthy person who has never taken penicillin, is Sparky or Bailey most likely to survive and reproduce? Why?

Answer:

Bailey is most likely to survive

Edward Jenner’s smallpox inoculation experiment was based on an observation by a dairymaid that she could not get smallpox becau
9966 [12]

Edward Jenner inferred that a person who once had small pox cannot have it once again. So something is there in these persons which grows after the initial infection which interferes with the secondary infection resisting it.

<h3><u>Explanation:</u></h3>

Edward Jenner is called the Father of Vaccination. Jenner noticed that the milkmaids who deal with the cows all the time don't generally suffer from the cowpox or small pox. Then as an Experiment, he took some sample from the pustules of the cow having pox and then cleaned it and injected the sample into a healthy child. Then when everyone of the locality suffered from the same disease, that child remained healthy. So that lead to infer that there are something in the pustule which lead to resist the secondary infection of this disease. So this lead to the invention of vaccines.

Centromere repeats in humans are made up of alpha-satellite DNA, a ∼171 bp sequence or monomer that is iteratively repeated. Alpha-satellite monomers are arranged head-to-tail and organized into repeated arrays called higher order repeats (HORs) that range from 0.2 to 5 megabases (Mb) and are chromosome specific.

satela [25.4K]

\huge\boxed{\text{D.}\ 60\ \text{nautical miles}}

1 minute of latitude is equal to 1 nautical mile.

Just like an hour of time, there are 60 minutes in a degree of latitude.

Therefore, there are 60 nautical miles in each degree.
