The right answer is <span>A) semi-permeable membrane
<span>A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).
</span>The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).</span>
Answer:
The answer is 50
Explanation:
Hemophilia is a X-linked disease. That means the recesive allele which causes the disease is not in Y chromosome, but only in X chromosome. If we denote:
X⁺ : dominant allele
X⁻: recesive allele
Then, in a woman there are three posibilities:
X⁺X⁻: is a carrier woman (without hemophilia)
X⁺X⁺: healthy woman
X⁻X⁻: woman with hemophilia
But in a man there are two posibilities:
X⁺Y: healthy man
X⁻Y: man with hemophilia
A man with hemophilia is X⁻Y, and a healthy woman whose mother had hemophilia is a carrier woman (X⁺X⁻). If they have a child, there are 4 posibilities, and each one has 1/4 of occurrence probability:
X⁻Y x X⁺X⁻ = X⁻X⁺, X⁻X⁻, X⁺Y, YX⁻
Posibilities with hemophilia are X⁻X⁻ and YX⁻ (1/4 + 1/4= 1/2= 0.5= 50%)
In each filial, there is a 50 percent of probability of having a child (man or woman) with hemophilia.
Sunlight, CO2, and H20 react to yield C6H12O6 (glucose), ATP, and O2
Nucleotides are phosphate group sugar and a nitrogen base
