Answer:

It is the conversion of CO2 into organic compounds and it forms 3-PGA.

Explanation:

Carbon fixation is one of the three stages in which the light independent phase of photosynthesis is divided into. It is the process whereby CO2, an inorganic source of carbon, is accepted by RUBP, leading to the formation of a 6-carbon compound that disintegrates into two 3-carbon molecules due to its instability.

The 3-carbon compounds are 3-phosphoglycerate or commonly known as 3-PGA. The carbon fixation stage is followed by reduction stage.

Which of these is classified as an emerging virus that can have a direct impact on human health?

umka21 [38]

Answer:

The correct answer is: D. Ebola.

Explanation:

Ebola Virus is a single-stranded RNA (ribonucleic acid) virus.
The natural host of the virus is Fruit bat but it can also infect humans.
The transmission of the virus into humans is mediated from infected bats through body fluids.
The major disease caused by the virus is is Hemorrhagic fever. In this disease, the platelet (responsible for clotting of blood) count in the blood drops far below normal. As a result, bleeding can get initiated both in the body interior or exterior. This disease can cause multiple organ failure and death.
Recently, in the year 2018, the Central African country, Democratic Republic of Congo experienced a severely fatal endemic due to the Ebola virus that killed many people within a short period of time.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?

yuradex [85]

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.
