Weekly Quiz Competition

Question 1
1 / -0

Excessive exposure of human to UV rays results in:
(i) Damage to immune system
(ii) Damage to lungs
(iii) Skin cancer
(iv) Peptic Ulcers

A
(i) and (ii)

B
(ii) and (iv)

C
(i) and (iii)

D
(iii) and (iv)

Solution

Harmful U.V rays are sufficient enough to cause skin cancer and damage the immune system of human body.
So, the correct answer is (C).
Question 2

Ramesh started going for a regular morning walk for controlling his blood sugar level. After a month, he started practicing yoga for a month. He underwent pathological test after two months and found that the blood sugar level has come down. Presuming that he had not changed his food habits during these two months, which statements given below follows most logically?

A
Blood sugar level comes down after doing regular morning walk.

B
Blood sugar level comes down after yoga

C
Blood sugar level rises on doing regular morning walk, yoga or both may raise sugar level despite not changing food habits

D
Regular morning walk, yoga or both may bring down sugar level despite not changing food habits

Solution

In diabetes patients, the cells do not respond to the insulin. Doing walk or exercise our body uses more glucose from the blood stream. Over time this lowers the blood sugar level and also makes the insulin in our body work better. Yoga acts on the endocrine gland of our body and regulates the body functions. It massages and tones the abdominal organs like pancreas and liver stimulate the nervous and circulatory system which in turn helps in controlling diabetes. So, the option D is correct.
Question 3
1 / -0

Leukaemia, a cancer is due to

A
Excessive production of WBCs

B
Excessive production of RBCs

C
Less production of platelets

D
Less production of WBCs

Solution

Leukaemia is cancer of blood-forming cells. Leukaemia usually causes large numbers of white blood cells to be made. These abnormal cells usually can't carry out the normal functions of white blood cells. They crowd the bone marrow and spill into the blood and may then spread into organs such as the liver, spleen, lungs and kidneys. Sometimes, they may also spread into the fluid around the brain and spinal cord. Because, there are so many abnormal white cells crowded into the bone marrow, the marrow sometimes can't make enough normal red blood cells, white blood cells and platelets.
Therefore, the correct answer is option A.
Question 4
1 / -0

What is diapedesis?

A
A kind of amoeboid movement

B
Process of coming out of WBC through the capillary wall to fight against foreign micro-organism

C
A type of locomotion found in hydra

D
The process of filtration of urea in kidney

Solution

Diapedesis is the process of coming out of WBC through the capillary wall to fight against foreign microorganism.
Diapedesis - The movement or passage of blood cells, especially white blood cells, through intact capillary walls into surrounding body tissue. Also called migration.
The movement of white blood cells and other cells out of small arterioles, venules, and capillaries as part of the inflammatory response. The cells move through gaps between cells in the vessel walls.
So, the correct answer is option B.
Question 5
1 / -0

Leukaemia a cancer is due to

A
Excessive production of WBCs

B
Excessive production of RBCs

C
Excessive production of platelet

D
All of the above

Solution

Leukaemia is a cancer that affects the blood and bone marrow where blood cells are made.
Leukaemia is cancer of blood-forming cells. Leukaemia usually causes large numbers of white blood cells to be made.
These abnormal cells usually can't carry out the normal functions of white blood cells. They crowd the bone marrow and spill into the blood and may then spread into organs such as the liver, spleen, lungs and kidneys. Sometimes, they may also spread into the fluid around the brain and spinal cord.
Because, there are so many abnormal white cells crowded into the bone marrow, the marrow sometimes can't make enough normal red blood cells, white blood cells and platelets.
Question 6
1 / -0

The artificial stimulation of resistance to diseases is called

A
Embolism

B
Immunisation

C
Sterilisation

D
All of the above
Solution
Embolism is the blockage in the blood vessel due to a clot or obstruction by a foreign particle. It decreases the flow of the blood and causes fatal consequences.
Immunisation is the process of inoculating the live or killed virus which activates the immune response towards the harmful pathogen. The suspension of microorganisms is heated to remove the virulence so they do not cause the disease but antibodies are released in response to the pathogen.
Sterilization is the process by which harmful pathogenic microorganisms are killed to avoid contamination. Heating, fumigation, and chemical treatment are some of the important methods of sterilization.
So, the correct answer is option B.
Question 7
1 / -0

Elephantiasis is transmitted by

A
Housefly

B
Mosquito

C
Bedbug

D
Fruit fly

Solution

Lymphatic filariasis, commonly known as elephantiasis, transmitted by female mosquitoes. When an infected female mosquito bites a person, she may inject the worm larvae into the bloodstream. Therefore infection occurs when filarial parasites are transmitted to humans through mosquitoes. So, the correct answer is option is B.
Question 8
1 / -0

Vaccines are

A
Same as monoclonal antibodies

B
Treated bacteria or viruses or one of their proteins

C
MHC proteins

D
Strands of nucleic acids
Solution
Correct option: (B)

Explanation for correct option:
- Vaccines are used to provide immunity against a pathogen by exposing our immune system to dead or inactive bacteria and viruses or their proteins.
- These dead or inactive viruses or bacteria or their proteins do not cause the disease but rather train our immune system.
- So that our immune system retains a memory of this exposure and use this memory to fight these pathogens in case of future exposures.
Question 9
1 / -0

Interleukin which is recently discovered, is a cure for

A
Arthritis

B
Diabetes

C
Cancer

D
Influenza

Solution

Interleukin are small proteins that are produced by a variety of cell types, especially T cells and other white blood cells, that regulate many aspects of inflammation and the immune response, including stimulating the production of white blood cells and platelets. The function of the immune system depends in a large part on interleukins and rare deficiencies of a number of them have been described, all featuring autoimmune diseases or immune deficiency. The majority of interleukins are synthesized by helper CD4 T lymphocytes, as well as through monocytes, macrophages and endothelial cells. They promote the development and differentiation of T and B lymphocytes and hematopoietic cells. Interleukin may be used to combat some forms of cancer.
Question 10
1 / -0

Excessive consumption of alcoholic drinks causes damage to

A
Liver

B
Kidneys

C
Heart

D
Lungs

Solution

Alcohol is readily absorbed from the digestive tract, and up to 98% is metabolised in the liver. Each liver cell contains three pathways for alcohol metabolism. All of these result in the production of a highly toxic metabolite which can contribute to liver cell damage. With regular alcohol use, the regenerative ability of liver cells may be inhibited and lead to sustained liver damage. Long term heavy alcohol use may lead to fat accumulation in the liver, which may progress to alcoholic hepatitis, or liver cirrhosis.
Therefore, the correct answer is option A.
