Under the influence of antidiuretic hormone (adh), _____ is produced. under the influence of antidiuretic hormone (adh), _____ i
leva [86]
I think under the influence of Antidiuretic hormone (ADH), more concentrated urine is produced. Antidiuretic hormone also called vasopressin acts to maintain blood pressure, blood volume and tissue water content by controlling the amount of water and hence the concentration of urine excreted by the kidney increases. It also helps to control blood pressure by acting on the kidneys and the blood vessels.

A genetic locus has two alleles. One has a frequency of 0.12; the other has a frequency of _______.
saw5 [17]

Answer:

Option A

Explanation:

As per the first equation of equilibrium of Hardy Weinberg, the sum of frequencies of alleles at the locus is equal to unity.  

Thus,  

If "p" represents the frequency of dominant allele, "q" represents the frequency of recessive allele and at equilibrium

p + q = 1\\

Let us assume that value of q is given in question which is equal to 0.12

On substituting the given values in above equation we get -

p + 0.12 = 1\\p = 1-0.12\\p = 0.88

Hence, option A is correct

Why is it important for DNA Replication to produce exactly identical DNA daughter strands?
IgorC [24]

DNA is generally tightly packed into a structure called chromatin. It is double stranded and twisted into a structure called a double helix. In order to replicate, DNA must unwind. After unwinding, each side of DNA separates by unzipping down the middle, with the two unzipped strands serving as templates for creating new strands. At the end of replication, the two new segments of DNA each contain one old and one new strand.

Replication occurs at different rates in different types of cells. Some cells continuously divide and must constantly replicate their DNA. Other cells divide at a much slower rate and do not need to replicate their DNA as often. Some cells divide until the organ they make up reaches its normal size, and then they do not divide again.

DNA stands for deoxyribonucleic acid. Each strand of DNA is made up of a sugar, a phosphate and a nitrogenous base bonded together into a structure called a nucleotide. Many nucleotides bond together to form DNA.
