DIFFERENCES FROM PAST PAPERS (1995)

1. Hypoglycaemia & Hyperglycaemia

Hypoglycaemia:
i) The fall in sugar level in the blood below the normal physiologic level known as Hypoglycaemia. Normal physiologic range of sugar in blood is 60-90mg% at fasting and 120-140 mg% at random.
ii) It is treated by giving intravenous glucose.
iii) It causes mental confusion, visual problem and often coma etc.
iv) It causes weakness and increases in food desire.

Hyperglycaemia:
i) Hyperglycaemia is a condition in which blood sugar level rise above its normal range.
ii) It is treated by exercise, medicine or by intravenous insulin therapy.
iii) It causes weakness, calf pain, unhealed wounds and kidney problem.
iv) It causes excessive urination, dryness of lips and increased thirst etc.

2. Epidemic & Endemic

Epidemic:
i) If at one place and times a great number of people suffer from a disease is known as epidemic.
ii) It can travel from one place to another.
iii) Examples: Influenza, Smallpox, Cholera etc.

Endemic:
i) If a disease persists in a particular locality, certain area or one region, it is known as endemic disease.
ii) It cannot travel from one place to another place.
iii) Example: Goitre in iodine deficient areas.

3. Herbivores & Carnivores

Herbivores
i) The animals eating green plants, grass and fodder are known as Herbivores.
ii) Animals have specific digestive system to digest leaves, plants and fodder.
iii) The teeth are specifically designed to cut and chew leaves, plants and fodder.
iv) Jaw movement is specific for side motion.
v) Examples: goats, cattle, sheep, buffalo, cow etc.

Carnivores:
i) The animals eating flesh and meat are known as carnivores.
ii) Digestive enzymes are specific.
iii) Their teeth are short and to cut and chew leaves, plants pointed especially for flesh eating.
iv) Jaw movement is specific for up and down movement.
v) Examples: Tiger, dog, cat, lion etc.

4. Respiration & Photosynthesis

Respiration
i) Respiration is a catabolic process in which compounds are broken down.
ii) In this process carbohydrates are broken down into simpler compounds.
iii) The end-products for this process are CO2 and H2O.
iv) In respiration Oxygen enters the plant body and CO2 is released.
v) It occurs during both day and night. Light is not necessary for this process.
vi) In respiration energy is released from food material.

Photosynthesis
i) It is an anabolic process in which compounds are formed.
ii) In this process carbohydrates are manufactured.
iii) The end-product of this process is simple carbohydrates.
iv) In photosynthesis CO2 enters the plant and O2 is released.
v) It occurs during day time only. Light is essential for this process.
vi) It is energy consuming process.

5. Pollination & Fertilization

Pollination
i) It is a process involving transfer of pollens form male reproductive organ to female reproductive organ of plants.
ii) It occurs in flowering plants.
iii) The products of pollination are seed.
iv) It takes place through animals, birds, insects, wind and water.

Fertilization:
i) In fertilization fusion of egg and sperm occurs.
ii) It occurs markedly in animals.
iii) The product of fertilization is zygote.
iv) It takes place by physical contact and mating of male and female.
