What is electrolyte balance in the body?
Vlad1618 [11]

The electrolytes present in our body should be in the right concentration. This is said to be electrolyte balance.

Why does an electrolyte imbalance occur?

Electrolyte imbalance is caused when the body fluids are present in large amount. When we sweat or vomit more, it can be due to the lower level of some electrolytes. So, it is necessary that the electrolytes should be in proper proportion.

Electrolytes plays a very important role in our body. It helps in regulation of fluids present in blood and blood plasma, normalizes the pH of blood, allows the contraction of muscles and so on. For all these necessary roles to occur, our electrolytes should be in proper concentration. This is called electrolyte balance.

In a certain plant, fruit color is affected by an epistatic interaction between two genes. The fruit is red in the presence of a
sukhopar [10]

Answer:

15/16 or 93.75%

Explanation:

<em>The proportion of the offspring of the cross expected to be red would be 15/16 or an equivalence of 93.75%.</em>

Red fruit color is conditioned by the presence of A_, B_ or A_B_ alleles. In the absence of both dominant alleles, the condition is white. AaBb was crossed with AaBb.

AaBb   x   AaBb

Progeny' Genotype       Phenotype

1 AABB                               red

2 AABb                               red

2 AaBB                                red

4 AaBb                                 red

1 AAbb                                 red

2 Aabb                                  red

1 aaBB                                  red

2 aaBb                                  red

1 aabb                                   white

Hence, the proportion of the offspring that are expected to be red is 15/16 or 93.75%.
