Answer : Option A) He asked what would happen if he deliberately inoculated someone with cowpox fluid from another person.
Explanation : Edward Jenner wanted to know what would happen if he deliberately inoculate the cowpox fluid from some person to another. He tested this experimental results and later on came up with the hypothesis. Which roughly state that someone will not get smallpox because they already had cowpox.
The time taken to double the population is 58 years.
<h3>What is exponential growth?</h3>
An exponential growth problem is one for which we define the model; P= Poe^rt
Where;
P = population at time t
Po = initial population
r = population growth rate
t = time taken
1800000 = 900,000e^(0.012 × t)
1800000/900,000 = e^(0.012 × t)
2 = e^(0.012 × t)
ln2 = 0.012 × t
t = ln2/0.012
t = 58 years

Answer: Rearrangement of Base sequence
Explanation: Indel mutation- Inserts- deletion mutation is the removal of nucleotides from a DNA sequence as in Inserts or addition of new nucleotide to the sequence.
Indels can result in a shift in the DNA sequence(frame shift Mutation),or formation of entirely new protein outside the original sequence.
Indel have being said to be the cause of some disease, some Indels are used as genetic markers in natural population.
When guanine is deleted a new base is formed UGG AUG UCC CCA UA...a shift occur leading to the formation of new base pair.
