AIIMS Biology Mock Test - 3 - Question 3

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): Smaller the organism higher is the rate of metabolism per gram weight.
Reason(R): The heart rate of a six month old baby is much higher than that of an old person

Detailed Solution for AIIMS Biology Mock Test - 3 - Question 3

The basal metabolic rate is defined as the energy requirement of the human body at rest reflects the caloric needs of the body.BMR can be determined by total body weight and the amount of muscle mass. BMR is inversely related with the weight or volume of an organism, which means the smaller the organism higher is the basal metabolic rate.
Heart rate of six month old baby is 110 to 112 beats/minute. Though it is higher then normal adult person, but it is lower than the old person.At the age of 60 years a man have maximum heart rate of 160 beats/minute.

Reason(R): No value is attached to these forests because these are poor in biodiversity.

Detailed Solution for AIIMS Biology Mock Test - 3 - Question 7

Tropical rain forests are disappearing fast from developing countries such as India. Forest lands are converting into agricultural and industrial lands to fulfil the requirements of increasing population. Tropical rain forestsd are rich in biodiversity.

AIIMS Biology Mock Test - 3 - Question 8

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): Diabetes insipidus is marked by excessive urination and too much thirst of water.
Reason(R): Anti-diuretic hormone (ADH) is secreted by the posterior lobe of pituitary gland.

Detailed Solution for AIIMS Biology Mock Test - 3 - Question 8

Anti-diuretic hormone (ADH) or vasopressin is a peptide hormone, synthesized in the hypothalamus and released by the posterior pituitary gland, that stimulates capillary muscles and reduces the flow of urine and increases its concentration. It is released in response to a fall in the water content of blood plasma and lead to an increase in the permeability to water of the distal and collecting tubules of the nephron. Deficiency or hyposecretion of ADH results in diabetes insipidus.
Diabetes insipidus is characterized by micturating dilute urine several times a dday which results in excessive thirst and dehydration.

AIIMS Biology Mock Test - 3 - Question 11

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): Secreting hypotonic urine is effective in reducing urinary loss of water.
Reason(R): Hypotonic urine is more concentrated and higher in osmotic pressure than the blood.

Detailed Solution for AIIMS Biology Mock Test - 3 - Question 11

When there is a threat of excessive water loss from the body of the animal then the urine excreted needs to be hypertonic and not hypotonic because excessive water loss from the body possess the threat of a rise in osmoconcentration of blood. Since hypertonic urine is more concentrated and higher in osmotic pressure than the blood, therefore it helps in reducing the loss of water with urine.
Human urine is hypertonic which is more concentrated than the blood.So an isotonic glomeruler filterate is first filtered into the Bowman's capsules of nephrons in kidneys. The tubules of nephrons then reabsorb a large volume of water from the glomerular filtrate not accompained by the reabsorption of proportionate amounts of solutes. This leaves the urine more concentrated than the blood which is very effective in reducing the urinary loss of water.

AIIMS Biology Mock Test - 3 - Question 18

In the following question, a statement of Assertion(A) is given followed by a corresponding statement of Reason(R).
Read the statements carefully, and mark the correct answer.
Assertion(A): Interferons are a type of antibodies produced by body cells infected by bacteria.
Reason(R): Interferons stimulate inflammation at the site of injury.

Detailed Solution for AIIMS Biology Mock Test - 3 - Question 18

Interferons are not antibodies.These are defence proteins that are produced by body cells that are infected by a virus. They travel to nearby cells and prevent the spread of the virus.
Cells that have been infected produce chemical called histamine. This chemical causes the blood capillaries to dilate (get wider) and become more porous. As a result the area swells, gets red, becomes warm, and is painful. This results in more white blood cells coming to the area to fight the infection. If the inflammation happens over the whole body we get a fever. The fever is the body’s way to combat bacteria and viruses. The higher temperature inhibits the pathogen from reproducing.Interferons do not stimulate inflammation at the site of injury.

Reason(R): These are prepared by a group of cells that descended from many cells or by inbreeding of a completely heterozygous line.

Detailed Solution for AIIMS Biology Mock Test - 3 - Question 20

Clone is a group of cells descended from the same single parent cell. In most of the cases, nucleic acid sequences are said to be cloned when they are inserted into vectors such as plasmids and copied within host cells during gene manipulation.
