Malaria passes into the human population when a mosquito carrying the virus bites a human who has no immunity. The malaria paras

ite can remain for up to forty days in the blood of an infected person. The disease cannot be passed from person to person, unless a non-infected person is exposed to the blood of an infected person. Theoretically, malaria could be eradicated in any given area, if all the mosquitoes carrying malaria in that area are exterminated. If such a course of action is carried out at a worldwide level, then the global eradication of malaria is possible.
Which of the following, if true, suggests that the epidemiologist’s plan for eliminating malaria is not viable?
A. A person who is infected with malaria can infect a mosquito that is not carrying malaria, if that mosquito bites such a person.
B. Unless a mosquito bites an infected person, and then bites a non-infected person, malaria cannot be passed directly from human to human.
C. Malaria is still endemic in many parts of the world, and many health workers believe that the global eradication of malaria is not possible.
D. Some people in areas where malaria is rife have developed an immunity to mosquitos, yet they are also show a higher incidence of genetic disorders such as sickle-cell anemia.
E. Mosquitos in many developing parts of the world are responsible for passing on a variety of viruses to human hosts.

The answer is A

Explanation:
Malaria goes straight to the liver where it feeds and multiplies. It forms a schizont where it bursts into the bloodstream. A mosquito can drink the blood of the infected human and contract it, then pass it on to others. Even if it is completely clean. The life cycle occurs in two different hosts. Human and Mosquito.

Chain reaction

Nuclear energy

Explanation:

Question 1:

Chain reaction:

A reaction in which when one occurs, it starts a series of other fission reaction is called a chain reaction.

Most nuclear reactions are chain reactions in which does not come to rest in one step like chemical reaction.

In nuclear reactions like which fusion and fission, one step leads to another until an atom attains stability or a stable product is formed.

The energy needed to sustain the chain process is produced in the previous reaction.

Nuclear energy:

The type of energy used in a nuclear power plant is called a nuclear energy. Nuclear energy is used to generate power in nuclear plant.

During a nuclear decay process, a huge amount of energy is released. This energy is channeled into electricity production and to do other useful works.

Nuclear energy is classified as a non-renewable source of energy.

Cite the most common molecular explanations for dominant and recessive alleles.
tangare [24]

Answer: Dominant allele codes for a functional protein. Recessive allele codes for a less functional or nonfunctional protein, or it does not code for any protein.

Explanation:

Alleles are different forms of a gene. There are two types, dominant and recessive allele. Heterozygous organisms have one of each, and the dominant allele is expressed. Homozygous organisms have either two dominant alleles or two recessive alleles.

<u>A dominant allele produces a functional protein</u>, even in the presence of a recessive allele, because only one copy of the allele is enough and it masks the effects of the recessive allele. This dominant trait is shown in individuals who are homozygous dominant or heterozygous,

<u>A recessive allele produces a less functional or nonfunctional protein, or it does not code for any protein at all.</u> A recessive allele does not become a trait unless both copies of the gene are present.

In pea plants, the allele for inflated pod seed, I, is dominant over the allele for constricted pod seed, i. The Punnett square
scoundrel [369]

Answer:

II

Explanation:

Since 'I' is the more dominant trait and 'homozygous dominate' is asking for the same dominante feature, II should be the answer

Hope this helps!
