The Correct Answer is A
Reasoning - Since the ani. had went into a different ecosystem and habitat amd mateded it had offspring with the originally some genetic along with some little different variations. In turn this is call Founders Effect
Answer:
D) Na+ is used to repolarize the membrane.
Explanation:
Option D is wrong choice because it is K+ which is used to repolarize the membrane not Na+.
As soon as membrane gets depolarized because of influx of Na+ due to opening of voltage gated Na+ channels simultaneous opening of voltage gated K+ channels and closing of Na+ voltage gated channels takes place. As a result of which K+ moves out of the cell leading to drawing of electrochemical gradient out of the cell.
In order to achieve resting membrane potential, more Na+ must be out of the cell and more K+ must be inside the cell. There are many leaky channels on neurons from which Na+ has tendency to leak into the cell while K+ has the tendency to leak outside of the cell. So Na+/K+ pump which is located on the membrane of neuron keeps pushing Na+ outside of the cell and K+ inside the cell so as to maintain resting membrane potential which is -70 mV.
Explanation:
On average, the temperatures are always high. A lot of rain (rainy season) falls in the month of: July, August and September. Bamako has dry periods in January, February, March, April, November and December. The warmest month is April with an average maximum temperature of 39°C (102°F).

Answer: DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans. Like DNA, RNA is made up of nucleotides. ... There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
