Solutions:

Ans 1 (d):

Krill feed on phytoplankton, microscopic, single-celled plants that drift near the ocean’s surface and live off carbon dioxide and the sun’s rays. Orca is killer whale that’s feeds on, among others, the hapless seals.

Ans 2 (a):

Scurvy due to deficiency of Vitamin C
Night Blindness due to deficiency of Vitamin A
Rickets due to deficiency of Vitamin D

Ans 3 (b):

Ans 4 (c):

Ans 5 (d):

Three common hereditary disorders are Thallasemia, Haemophilia and colour blindness.

a) Thallasemia : Patients suffering from this disorder are unable to manufacture haemoglobin, the pigment in red blood corpuscles which carries oxygen to tissues. This is because the pair of genes controlling hemoglobin production are defective. Thallasemics (persons suffering from thallasemia) require frequent blood transfusion in order to survive.

b) Haemophilia : Those persons suffering from haemophilia have either a defective gene or lack genes, which control production of substances responsible for blood clotting. In the absence of such substances blood does not coagulate. So, once bleeding starts, it does not stop.

c) Colour blindness : Different kinds of colour blindness are met with but commonly those suffering from this genetic disorder are unable to distinguish blue colour from green. Again, this is due to the presence of a defective gene or absence of a gene.

Ans 6 (c):

It is the latest application of GPS helpful in commercial activities to find out location of ATM card if it is missed and internal clocks are used to determines the exact financial transactions through the use of GPS satellite linkages.

Ans 7 (b):

Ans 8 (c):

Ans 9 (a):

Macro-elements: Carbon, Hydrogen, Oxygen, Nitrogen, Sulphur, Phosphorus, Calcium, Magnesium, Potassium Micro-elements: Copper, Zinc, Molybdenum, Boron, Manganese, Chlorine, Iron

Ans 10 (a):

Biotechnology Industry Research Assistance Council (BIRAC) is a not-for profit Section 8, Schedule B, Public Sector Enterprise, set up by Department of Biotechnology (DBT), Government of India as an Interface Agency to strengthen and empower the emerging Biotech enterprise to undertake strategic research and innovation, addressing nationally relevant product development needs.
