Here we are giving short answer questions for the benefit of Tenth Class / SSC / 10th Class students of Andhra Pradesh Board. The question are useful for 2 marks questions and will be asked in Section II of Paper 2. Each question carries two marks.
1. Write short notes on agglutination of blood.
Ans: When the blood samples of different persons are mixed with one another, red blood cells present in those samples interact and clumps are formed. This is agglutination of blood. If this happens in the blood vessels of a person, these clumps block and prevent the flow, leading to the death of the person who receives the blood.
2. What are respiratory substrates? Give two examples.
Ans: substances which are oxidized in the body of organisms during respiration to produce energy are called respiratory substrates.
Eg: carbohydrates and fats are the major respiratory substrates in all organisms.
3. Where do you find cerebrospinal fluid and what are its functions?
Ans: a fluid which flows in between the outer and middle membranes is called cerebrospinal fluid. This flows from brain to spinal cord and back to brain.
It protects brain and spinal cord from injuries and provides nutrients to the cells in the brain and spinal cord.
4. Write short notes on tetany.
Ans: if the parathormone secretes in large quantities, the muscles become very active and remain the contracted state. This condition is called Tetany.
5. Write short note on Hermaphroditism in animals.
Ans: When the male and female sex organs are present in the same animal, such animals are called hermaphrodites. Eg: Earthworm.
6. What is embryo rescue? When is this method followed?
Ans: there are certain embryos that do not develop inside the ovary. To get plants form these embryos, they must be grown in culture media. This is called embryo rescue. Plants tolerant to drought, pathogens etc., can be isolated by creating these conditions in the culture medium. New hybrid species can be evolved by tissue culture.
7. Describe the duties of village health guide.
Ans: The duties of the health guide are:
Giving treatment of simple ailments.
Giving first aid.
To provide information on sanitation, mother and child care.
Small family norms.
8. what are corals? Write their importance.
Ans: Corals are the wonderful life forms that grow in marine waters at depths, where the sun’s heat and light can reach them.
Most corals are brightly coloured due to the presence of natural pigments in them or due to the algae living within them.
Some of the coral scan form strong rocky layers called coral reefs.
Among the plants and animals on the earth, coral reefs are the most ancient. When the coral environmental system is affected by pollution in the marine water, the algae lose their colouring pigments and the coral reefs turn white.
Coral reefs provide shelter to smaller animals such as worms, snails, sea-fish, sea cucumbers, sea urchins, octopuses etc.
10th Class Biology Very Short Answer Questions - Paper 2
Following are very short answer questions and answers for SSC / 10th Class students of AP Board. The questions will carry 1 mark each.
1. what is epiglottis?
Ans: the cartilaginous flap which acts as a lid over the glottis preventing the food from entering the larynx is called the epiglottis.
2. what is a target tissue?
Ans: the tissues or organs on which the hormones act are called target tissues or target organs.
3. what is callus?
Ans: when explant is placed in culture medium, the cells of the explant divide and re divide to produce an undifferentiated mass of tissue called callus.
4. what is incubation period?
Ans: the time elapsed between the entry of disease causing organism into the body and the appearance of the sickness is called incubation period.
5. why do sports persons take Glucose?
Ans: glucose being a simple sugar is immediately absorbed into the blood. So, sports persons and diseased persons take glucose.
6. what are carbon sinks?
Ans: the grasslands that absorb carbon dioxide from the atmosphere are called carbon sinks.
