Answer:
B. Glucagon
Explanation:
Glucagon is a pancreatic hormone, secreted by the alpha cells of islets of Langerhans. Whenever the blood glucose level falls, glucagon is released to increase the blood glucose levels. This function of glucagon is quite opposite to the function of insulin and hence both are antagonistic hormones. Insulin reduces the blood glucose where as glucagon increases the blood glucose.
Glucoagon is large polypeptide of 29 amino acids. Since it helps in increasing the blood glucose homeostatic levels it is called as hyperglycemic hormone. It does so by stimulating certain processes such as:
- Stimulating Glycogenolysis i.e breakdown of glycogen to release more glucose from liver.
- Stimulating Gluconeogenesis i.e. synthesis of glucose from non-carbohydrate sources like proteins.
- Glucagon inhibits the process of glycogenesis i.e. synthesis of glycogen, the storage form of glucose.
A marmoset is a member of the family of primates and are known to be one of the smallest monkey. They are measured to have a body length of 12 - 15 inches and has a mass of approximately 100 - 125 g. Comparing to monkeys, marmosets have distinct characteristics. Instead of having nails, they have claws, they tactile hair or a sensitive hair found on their wrists. They do not have wisdom teeth and the layout of their brain is primitive.

Answer:
The Markonikov's rule determines where to add a nucleotide in the reaction
Explanation:
In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.
