Beans may be tall or short depending on one locus, and they may have long or stubby pods, depending on another locus. A tall, st

ubby plant was crossed with a short, long plant. The F1 plants were all tall and stubby. Which of the following PHENOTYPES do you expect to occur least often in the F2?"

Answer:

c. "short, long"

Explanation:

The question being described involves two different genes; one coding for beans length and the other for pod length. According to the question, beans may be tall (T) or short (t) while they can also have have long (L) or stubby pods (l).

From the phenotypic ratio result of the F1 generation, which were all tall and stubby, it is clear that tall bean (T) and stubby pods (d) are highest balloon. According to Gregor Mendel's ratio of dihybrid cross; 9.3.3:1, the least occuring phenotype, which is 1 of 16, can be "short, long".

"The total concentration of receptors in a sample is 10 mM, and the concentration of free ligand is 2.5 mM. Calculate the percen
Mice21 [21]

Answer:

16.66 %

Explanation:

The receptors that are bound with the ligand can be calculated by the formula as follows:

Kd = [R] [L]/[RL]

Here, Kd is dissociation constant = 1.5 mM

R is free receptor concentration = 10 mM

L is free ligand concentration = 2.5 mM

The values needs to be constitute to find the percentage  of receptors that are bound to ligand.

Put all the values

1.5 = 10 × 2.5 / RL or RL = 25 /1.5

So RL = 16.66

Hence 16.66 % of receptor is bound to substrate.

Thus, the answer is 16.66%

IrinaVladis [17]

Considering answers;

-fever

-constricted veins

-swollen veins

-confusion


Answer;

Swollen veins


Swollen veins might be a symptom of a person whose vein valves are not functioning properly and are causing fluid it flow away from the heart.


Explanation;

Valves are structures that are found in the circulatory system both in the heart and the veins.

They function to prevent the back flow of blood.

They do so by ensuring the continuous flow of blood in one direction.

If the valves are not functioning properly it may lead to various effects such as swollen veins due to the back flow of blood which may lead to the pooling of blood in the extremities.
