Answer: position of the carbonyl carbon
Explanation:
In the linear structure of sugars having an aldehyde group, are called aldoses, and sugars having a keto group are called ketoses.
Like adehydes H-C=O the carbonyl carbon is the first/last in the chain it is bounded to Hydrogen, double bounded to oxygen and a single bond to the chain. An aldose linear sugar like D-glucose have the carbonyl carbon as it first carbon.
But ketones R-COR the carbonyl carbon is in between the chain, it is bounded to two carbons on both sides. Like D-fructose the keto carbon is the second carbon.
In a open ring structure the 1st carbon, adehyde group is condensed with the hydroxy group (OH) of the 5th carbon forming a ring. The first carbon is now bound to the chain, Hydrogen, OH and oxygen which forms the ring.
In the keto open ring structure of D-fructose, the second carbon(keto group) is condensed with the OH of the 5th carbon
Answer:
The correct answer will be option-Telomerase is an enzyme that increases the length of linear chromosome ends
Explanation:
Telomerase is a reverse transcriptase enzyme which adds the length of DNA by adding the guanine-rich repetitive sequences called telomeres at 3' end of the DNA.
The enzyme not only adds the telomere but also maintain its length in the organism. The telomerase activity possesses several roles one of which is that it protects the end of the DNA from DNA damage and neighbouring chromosomes.
Since telomerase adds the repetitive sequences at the end and thus increases the length of the DNA thus is the correct answer.
Answer:
Absorbs water and nutrients
Explanation:
That’s what the roots do
Answer:
The correct answer is option C.sending white blood cells to the site to try to repair the damaged
Explanation:
Atherosclerosis is a disease where plaque develops inside arteries. Arteries are vessels that convey oxygen-rich blood to your heart and different regions of your body. Plaque is comprised of fat, cholesterol, calcium, and different substances found in the blood. After some time, plaque solidifies and limits your supply routes.
The immune system responds to Atherosclerosis that causes damage to the arteries by sending white blood cells to the damaged site to fix the damage caused by the plaques and fat deposits that obstruct the blood supply.
Bc it makes up your genes
