In the lumen of the proximal tubule, Na concentration is ________ the Na concentration inside the cells of the tubule wall.

Biology

nydimaria [60]2 years ago
3 0

Answer:

The correct answer is - higher than

Explanation:

In the lumen of the proximal tubule of the kidney, most of the solutes are absorbed in the form of sodium. There is a gradient of sodium ions which allows the absorption of the solutes from the lumen into the cell.

It is due to the solute or  Na concentration is higher in the lumen than Na concentration inside the cells of the tubule wall. So movement of the solutes is due to the concentration gradient.

In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant al
ICE Princess25 [194]

Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8
