Originally, there were only five bacterial cells. After one month, the amount of bacteria is doubled with ten bacteria. The growth is represented by the formula:
a42 = 5 x 2^1
After 42 months, the growth can be solved using this formula:
a42 = 5 x 2^42

Orlov [11]

Not sure what you mean by understanding reflection but i'll do my best.

World War II was one of / if not the biggest tragedy to happen in modern history. It taught the world important lessons about society; that we need to work together and not let our differences enable another global conflict to the degree of WW2. However, history never completely repeats itself and while WW2 was a terrible and unimaginable tragedy, it provided us with information that can help us all in avoiding a future conflict similar in nature. However, how is the author so certain that history doesn't repeat itself? Have we not seen history do such thing. For example, there were vaccination protests all throughout history just like how there is vaccination protest today. So, I am interested in how the author came to his conclusion that WW2 will not inevitably repeat itself.

il63 [147K]

Answer:

There are no options to this question, however, the question can be answered. The answer is:

FF and FF/Ff

Explanation:

This question involves a single gene coding for possession or not of freckles in humans. The allele for freckles (F) is dominant over the allele for no freckles (f). This means that genotypes FF and Ff (heterozygous) will possess freckles while only genotype ff will not.

According to this question, a couple has several children in which all of the children have freckles i.e. have either genotype FF or Ff. This is as a result of the fact that the parent's genotypes were either FF or Ff. That is, one parent is FF while the other is either FF or Ff. This genotypes will only produce children with freckles.
