Answer:
The correct option is A
Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.
Explanation:
Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.
Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.
For the first question, the answer is C. green because a phenotype is the physical characteristics of an organism that can be seen. Of the options given, only green is a characterisitc that could be seen.
For the second question, the best answer is A. somatic because somatic mutations occur in the gametes.
Chem was fun last year XD
Anyway..
To find how many neutrons are in element x:
We take the mass number and subtract it with the atomic number
So, 75-22=53 neutrons...BOOM! :D
Microfilaments, Microtubules and Intermediate filament
Answer:
C) 91%
Explanation:
First,
Express the Dominant phenotype as homozygous dominant(BB) and heterozygous(Bb).
Based on hardy-Weinberg equilibrium,
homozygous dominant (BB) Brown eye individuals will have the following percentage
B × B
(Where B = 70%)
70% × 70%
= 49%
heterozygous dominant (Bb) Brown eye individuals will have the following percentage
Using 2 × B × b (where B =70% and b = 30%)
2 × 70% × 30%
= 42%
The proportion of the subsequent generation with brown eyes
(homozygous dominant, BB + heterozygous dominant, Bb)
= 49% + 42%
= 91%
