Answer: Option A. -> Human cells don't have cell wall.
:
A
The antibiotic penicillin blocks the bacterial processes that build the cell wall. Due to the lack of cell wall, the organism dies easily. Human cells don’t have a cell-wall. So penicillin cannot have such an effect on human cells.

Answer: Option B. -> Syphilis
:
B
All these are sexually transmitted disease (STDs).AIDS, hepatitis B and genital herpes are caused by virus. But not all STDs are caused by virus. E.g., syphilis andgonorrhea. The causative agent for them isbacteria. Syphilis is caused by Treponema pallidum,whilegonorrhea is caused by Neisseriagonorrhea respectively.

Answer: Option D. -> Cancer
:
D
Chronic diseases are those diseases which last for a long period of time and weaken the body by attacking the immune system. Cancer is an example of chronic disease. A cancer patient may suffer for many years to a lifetime in worse conditions.

Answer: Option B. -> Tuberculosis
:
B
∙ A chroniccondition is a human health condition that is persistent or otherwise long-lasting in it's effects. Tuberculosis is one such chronic disease. Other chronic diseases include cancer, diabetes, etc.
∙ Acute diseases occur suddenly and last only for a few days. E.g., Common cold, heart attack, etc.
∙ Congenital diseases, also called birth defects, can be acquired during the development of embryo or from genetic makeup of parents. E.g. Heart defects, down's syndrome, etc.
∙ Dietary diseases are caused due to deficiency or excesses of nutrients in the diet. E.g. Obesity, malnutrition, cardiovascular disorders, etc.

Answer: Option A. -> True
:
A
Effective prevention of infectious diseases in the community is achieved through access to public hygiene and immunisation.
A community with the availability of the better hospitals and resources like vaccines to improve immunity, medicines, clean environment etc. eliminates the disease first hand and contributes to the eradication of the infectious diseases effectively and permanently.

Answer: Option A. -> immune cells
:
A
The immune system of our body is specialised in killing the infecting organisms with the help of immune cells. These cells go into action each time when infecting microbes enter the body.

Answer: Option A. -> Immunity
:
A
The ability of an organism to resist disease, either through the activities of specialized blood cells or antibodies produced by them is termed as immunity.Some people are more immune against certain diseases than other people. Thus, immunity is responsible for giving protection against certain diseases to some people.

Answer: Option B. -> Many antibiotics are produced by bacteria.
:
B
Antibiotics are substances produced by some bacteria or fungi, or can even be produced synthetically. Antibiotics works against the pathogenic bacteria. Anitibiotics disruptthe cell wall formation in them and thus, killthe bateria and stop their multiplication.
Antibiotics work only against bacteria and simply attack them. They are not responsible for the strengthening of immune system. They have multiple side effects like diarrhea, nausea, vomiting, rash, stomach upset etc.
