Mass of the nucleons together in a heavy nucleus is

Options:
A Greater than mass of nucleus
B Equal to mass of nucleus
C Same as mass of nucleus
D None of the above

The correct answer is:
Greater than mass of nucleus

Solution:
When nuclear masses are measured, the mass is always found to be less than the sum of the masses of the individual nucleons bound in the nucleus. This difference between the nuclear mass and the sum of individual masses is known as mass defect. Hence
Mass of nucleons = isotopic mass + mass defect
Hence, mass of nucleons together in a heavy nucleus is greater than the mass of nucleus.

Mast cells of connective tissue contain:

Options:
A vasopressin and relaxin
B heparin and histamine
C heparin and calcitonin
D serotonin and melanin.

The correct answer is:
heparin and histamine

Solution:
Mast cells secrete heparin (and coagulant), histamine (vasodilator) and serotonin (vasoconstrictor) along with other enzymes and hormones such as cytokines, peptidoglycans, protease etc. relaxin is secreted by placenta. Calcitonin is secreted by thyroid gland. Melanin is secreted by dermal cells.
Related Theory
Mast cells contribute to homeostasis in the immune system. They serve as a first line of defense against antigens entering the body due to their location in the skin and mucosa.

Mast cells of connective tissues contain

Options:
A Vasopressin and relaxin
B Heparin and histamine
C Heparin and calcitonin
D Serotonin and melanin

The correct answer is:
Heparin and histamine

Solution:
Mast cells are granulated wandering leucocyte cells. Their granules contain histamine (vasodilator) and heparin (anticoagulant). They take part in body defence and allergic reactions. Vasopressin is released by the posterior lobe of the pituitary. Relaxin is released by the placenta. Calcitonin is released by the thyroid. Serotonin and melanin are released by the intermediate lobe of the pituitary gland.

Mast cells secrete:

Options:
A haemoglobin
B hippurin
C myoglobin
D histamine

The correct answer is:
histamine

Solution:
Mast cells are found in mucous membranes and connective tissues and are important for wound healing and defense against pathogens via the inflammatory response. The mast cell granules are composed of heparin and histamine. They secrete heparin, and histamine when they are activated due to toxic substance or pathogen. When released histamine cause blood vessels to dilate, increasing blood flow and cell trafficking to the area of infection. It is also involved in the inflammatory response. serotonin, a protein which acts as a vasoconstrictor to stop bleeding and to increase blood pressure is also released from mast cells.
Related Theory
As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues.

D 1- (ii), 2 - (i), 3 - (iii)

The correct answer is:
1- (ii), 2 - (iii), 3 - (i)

Solution:
Multiple alleles is a condition where more than two variants of the gene occupy the same locus. Mutation is change in the sequence of DNA segment. Mutation in the sequence of amino acids can result in formation of a new allele if the changes are simple and not on many bases. Multiple alleles combine in different combination to produce different phenotypes. Such variation in phenotypes occur due to the proteins encoded by the allele combination.
When traits are controlled by three or more genes, they are called polygenic traits and their inheritance is called as polygenic inheritance. Human skin colour is a classic example following polygenic inheritance as the skin colour is regulated by three pairs of gene. Polygenic inheritance is influenced by the environment as well and not just the polygenes.
Gene is a segment of DNA responsible for expression of proteins which in true expresses the character or feature represented by the gene. When this gene is regulating the expression of more than one feature in an organism such phenomenon is called pleiotropy.

Chromosomal disorder occurs when there is addition or deletion of chromosome in the individual. In case of trisomy of the 21st chromosome causes Down's syndrome. This results in mental retardation and physical development is retarded as well. The palm of the individual is broad with characteristic palm crease.
Phenylketonuria is an inborn error of metabolism where the individual has reduced metabolism of the amino acid phenylalanine. Such mutation leads to mental retardation, with reduction in hair and skin pigmentation. It is a recessive autosomal disorder.
Haemophilia are X-linked recessive disorder. X chromosome is part of the sex chromosome. In haemophilia, the individual has delayed clotting time for blood which can be fatal.
Sickle cell anemia is a type of genetic blood disorder which is inherited from the parents. The person suffering from it develops an abnormal haemoglobin that leads to elongated and curved or sickle shaped RBC. Such condition occurs when the individual inherits two abnormal copies of gene for beta globin chain of haemoglobin from each parent. It is an autosomal recessive disorder.

Solution:
Triglycerides are an ester of glycerol with three fatty acids and that are also known as triglycerol.
During glycolysis, glycerol 3-phosphate is generated from glucose which later on gets reduced to glyceraldehyde.
When the body doesn't use glucose so many glucose units join together and are stored in our body in the form of glycogen.
Glycolysis starts from the breakdown of glucose results into three-carbon compounds i.e. phosphoglyceraldehyde but in reverse glycolysis is gluconeogenesis in which glucose is formed.
