A. 12.5 m/s.
The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.
The formula that will allow you to calculate the average speed is:
v = d/t, where d is the traveled distance and t the time it took to travel the distance.
We hace to convert 4 minutes to second:
(60 s/1 min)*(4 min) = 240 s
So, the average speed is:
v = 3000 m/240 s
v = 12.5 m/s

Answer:
Each granddaughter cell is haploid (n)
Explanation:
Meiosis in the parent cell with a "2n" chromosome number would produce a total of four daughter cells. Each of these daughter cells would have an "n" number of chromosomes as separation of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in the daughter cells. Also, the event of crossing over and random segregation of homologous chromosomes makes the daughter cells of meiosis genetically different from each other.
Each of these four cells enters mitosis and forms a total of eight cells. Since mitosis maintains the chromosome number, each of the eight cells would have an "n" number of chromosomes and would be haploid.
When an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
<h3>What is an allosteric enzyme?</h3>
Allosteric enzymes are catalysts that exhibit a site for binding that is distinct from the active site.
Allosteric enzymes are controlled by many effector compounds that can bind to different sites.
The active site of the enzyme is the molecular domain of this protein where reactants can bind during a chemical reaction.
The heterotropic effects occur when the ligands of allosteric modulators (effectors) are linked to the enzyme.
An allosteric modulator is a molecule that binds to the enzyme in a site different to the active site and this binding alters its tridimensional conformation, thereby activating it or deactivating it.
In conclusion, when an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
