She could either have one child with AB, two children with B, and one child with A (genotypes: AB, BB, Ai, Bi), or have two children with B and two children with AB (genotypes: AB, AB, BB, BB).
Answer:
The two sisters though identical have some differences while the former avoids fatty meals and cholesterol the latter enjoys fatty meals in contrast with the statement they both exercise daily which burns out the fat
In normal situations:
-The thin ascending limb is of the loop of henle is impermeable to water. But, is permeable to ions (sodium, chloride) that cross by diffusion.
-Urine osmolality should be 300-900 mOsm/kg of water.
In this case, if the <span>ascending limb of the loop of henle is permeable to water is the same as saying the loop isn't doing it's job of </span>creating a concentration gradient.
Because of that, The process of reabsorption of water and creation of a concentrated urine is not correctly happening.
The answer is E<span>. minimum 300 / maximum 300
</span>
The loop of Henle receives isotonic (300 mOsm/L) fluid, from the <span>proximal convoluted tubule, and since it's not working th way it should it won't change those values. </span>
Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
