All of the above
Explanation :
Most bacteria that are associated with plants are actually saprotrophic, and do no harm to the plant itself. However, a small number, around 100 known species, are able to cause disease. Bacteria also cause diseases in animals and human beings. In humans, pathogenic bacteria cause infections such as tetanus, typhoid fever, diphtheria, syphilis, and leprosy. Among several, Leptospirosis is a bacterial disease that affects animals and humans.

[12] The cells which are responsible for the production of antibodies are -
A.
red blood cells
B.
neutrophils
C.
lymphocytes
D.
platelets
Ans:
lymphocytes
Explanation :
An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shaped protein produced by B-cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. Each antibody is produced by lymphocytes (specialized white cells) as a result of exposure to specific chemical substances called antigens usually on the outside of an invading organism. This is called the antigen-antibody reaction.
[13] Which of the following branches deals with the interactions of same species of living organisms with their nonliving environment?
A.
Autecology
B.
Synecology
C.
Ecology
D.
Palaeontology
Ans:
Ecology
Explanation :
Ecology is the scientific study of the relationships that living organisms have with each other and with their natural environment. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primaly production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment.

[9] The antibiotic Ampicillin is -
A.
a synthetic drug
B.
obtained from a bacterium
C.
obtained from a plant extract
D.
a semi-synthetic drug
Ans:
obtained from a bacterium
Explanation :
Ampicillin is an antibiotic made from bacteria. Belonging to the penicillin group of beta-lactam antibiotics, ampicillin is able to penetrate Gram-positive and some Gram-negative bacteria. It differs from penicillin only by the presence of an amino group. That amino group helps the drug penetrate the outer membrane of gram-negative bacteria.
[10] Which among the following blood protein regulates the amount of water in plasma?

[11] How many valves does a human heart have?
A.
Four
B.
Three
C.
Two
D.
One
Ans:
Four
Explanation :
Human heart has four valves: two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve; and two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve. A heart valve normally allows blood flow in only one direction through the heart.
[12] The cells which are responsible for the production of antibodies are -
A.
red blood cells
B.
neutrophils
C.
lymphocytes
D.
platelets
Ans:
lymphocytes
Explanation :
An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shaped protein produced by B-cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. Each antibody is produced by lymphocytes (specialized white cells) as a result of exposure to specific chemical substances called antigens usually on the outside of an invading organism. This is called the antigen-antibody reaction.
[13] Which of the following branches deals with the interactions of same species of living organisms with their nonliving environment?
A.
Autecology
B.
Synecology
C.
Ecology
D.
Palaeontology
Ans:
Ecology
Explanation :
Ecology is the scientific study of the relationships that living organisms have with each other and with their natural environment. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primaly production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment.
[14] Which of the following organelles is called 'Atom bombs'?
A.
Microtubules
B.
Nucleolus
C.
Golgi bodies
D.
Lysosome
Ans:
Lysosome
Explanation :
Lysosomes are known by names such as suicidal bags/ atom bomb and House keeper / scavenger of cell. They are called suicide bags or atom bombs because if the single membrane surrounding the digestive enzyme breaks, the enzymes released may also destroy the cell itself.
[15] Which of the following causes poliomyelitis?
A.
Dengue Virus
B.
Entero Virus
C.
Mumps Virus
D.
Rhabdo Virus
Ans:
Entero Virus

Poliomyelitis is caused by infection with a member of the genus Enterovirus known as poliovirus (PV).
[16] Which one of the following animals is sanguinivorous?
A.
Fruit-fly
B.
Mosquito
C.
House-fly
D.
Snail
