D hoped this helped you a lot! :s
22% cytosine, because each pair has an equal amount of complementary base percentages. For example, if you are given 20% Adenine, then there has to be 20% Thymine as well, and you can also calculate cytosine and guanine by looking at the remaining percentage (80%). Because 80% is left over and each complementary base pair has equal amounts of base percentages, Cytosine and Guanine would each have 40%.
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
The ring of fire is a circle that is covered with volcanos in its circumference. it erupts more that any other place because the more volcanos their are, the more these events will happen. another reason would be the tectonic plates. volcanos usually form on top of them. you must prepare for these events for your safety. their could be an earthquake any time, no mater where you are.
Answer:
D
Explanation:
Linoleic acid is an omega-6 fatty acid that is composed of an 18 carbon chain polymer. Most of the bonds are single bonds but few are double bonds. The double bonds form ‘kinks’ (bends) in the chains. The more the C=C bonds the more bendy the molecule. Nonetheless, it is significant to note that single (sigma) bonds are easy to rotate around their axis than double and triple (pi) bonds. The more the single bonds, the more flexibility the the molecule.
