Mechanical advantage is the answer.

Option B.

<h3><u>Explanation:</u></h3>

A machine is defined as the instrument which is used to perform some task easily, and with ease. A machine has the capability to give an output force in exchange of an input force. Now the ratio of the output force to input force is called as the mechanical advantage.

Mechanical advantage = Output force / input force.

For example, in case of a lever, there are three types - first class lever, second class lever, and third class lever. Mechanical advantage for a second class lever is always more than one, as we get more output force than input force. Similarly, the mechanical advantage for a third class lever is always less than 1, and mechanical advantage of first class lever can be both more or less or equal to one.

JulijaS [17]

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.

In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.
Jobisdone [24]

Answer: d). UAG

Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.

From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
