Answer:
33%.
Explanation:
The 4% population is red-hair due to the recessive mutation in melanocortin 1 receptor (MC1R).
Since, the population is in Hardy-Weinberg equillibrium- laet the frequency of recessive allele with red - hair is 'q' and the frequency of dominant allele in the population is 'p'.
q=0.2
According to hardy-weinberg equillibrium
(p+q)=1
p=1-q
p=1-0.2
p=0.8.
The total population with non red hair is calculated by
=
= 0.64 + 0.32
= 0.96
The percentage of the population with non red headed carrier for MC1Rr is calculated by:
=0.32/0.96*100
=33%
Thus, the correct answer is (B).

Answer:
Salmonella enterica (bacteria that causes food poisoning).
Explanation:
All living organisms has been classified into a main large group called DOMAIN consisting of three classifications: Eukarya, Archaea and Bacteria. The major basis of this classification is the possession of a true nucleus that houses the genetic material in the cells of living organisms.
Organisms that possesses a membrane-bound nucleus were classified to be under the domain Eukarya while those that didn't possess a nucleus were classified as Prokarya, which consists of the bacteria and archaea domains.
Based on the question, Salmonella enterica is a bacterium species, which means that it is a Prokarya and does not possess a membrane bound nucleus, hence, it would not be classified under the domain EUKARYA.
Microscopes are one of the laboratory tools used to maximize the visual acuity of a certain specimen, it maybe a living or non-living organism or object. Thus, microscopes are widely used in these laboratories to increase microscopic observation with entities that cannot be perceived thru the naked eye. However, for scientisits to determine such specimen is a living thing if there's a presence of cell. Cell cannot be viewed via the visual organs alone but with the microscope a living specimen can be discerned with its characteristics such as cellular structure, slight and fidgety movement and other particular details..
Answer:
cells have many structures inside of them called organelles.
