(b) Alloys cannot be separated by physical means, though it is considered mixture. Why?


(a) A pure substance has a fixed melting point or boiling point at constant pressure. The purity of a substance can be tested by checking its melting point or boiling point. If a substance is impure i.e. it contains traces of another substance, the melting and boiling point of that substance will change.

(b) Alloys are homogeneous mixtures of metals and cannot be separated into their components by physical methods. But still, an alloy is considered as a mixture because it shows the properties of its constituents and can have variable composition.

Q. (a) Name any one disease caused by bacteria and virus.
(b) Why are antibiotics effective against bacteria but not viruses?


(a) Disease caused by:

(b) Antibiotics are effective against bacteria but not against virus because they perform their activities with the help of their own host cells while bacteria has a different mechanism. Bacteria have cell wall. Antibiotics act by blocking the biochemical pathways which are essential for the survival of the bacteria. They prevent cell wall formation which causes the bacteria to die, thereby preventing bacterial diseases.

Q. What do you mean by active and passive immunisation?


Active immunisation: It promotes the production of circulating antibodies against foreign antigens by injecting a small quantity of modified antigen into the bloodstream.

Passive immunisation: It is the application of antibodies from an immune individual to non- immune patient. This treatment is used when an individual has been or probably will be, exposed to an infectious disease and there is insufficient time for active immunisation.
