Question 3

Antisnake venom is prepared by

Accepted Answer

Antisnake venom: In the Hoffkine Institute at Bombay snake venom in mild dose is injected into horses and the horses are induced to produce anti-venom bodies. These are extracted and used in cases of snake bites.

Question 4

Organisms that depend only on raw plant products are said to be

Accepted Answer

Herbivorous organisms are those that take for their food, plant parts like leaves raw in contrast to vegetarian, which means that plant products are taken raw or after being cooked.

Question 5

Man has _____ pairs of salivary glands

Accepted Answer

Salivary glands of man are 3 pairs = 6. They are one pair of parotid glands, one pair of sub-maxillary or sub-mandibular glands and one pair of sub-lingual glands.

Question 6

Damage to hearing is caused by sounds which exceed

Accepted Answer

High frequency sound attacks the tympanic memberane and makes it defective. 120 decibles is too high a pitch to be heard and therefore it impairs the hearing ability.

Question 7

Which of the following organelle is known as the 'Power House' of the cell?

Accepted Answer

Mitochondria are known as 'Power House' of the cell because they produce energy in the form of ATP.

Question 8

Who is known as father of Biology

Accepted Answer

Aristotle

Question 9

Transmission of stimuli from one part of body to other part takes place through __________

Accepted Answer

Nervous tissue

Question 10

Synapsis occurs during

Accepted Answer

Synapsis is the pairing of two homologous chromosomes that occurs during meiosis. It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them. Synapsis takes place during prophase I of meiosis. It is also called as Syndesis.

Question 11

Which of these is not a function of the kidneys?

Accepted Answer

The kidneys deactivate vitamin D and stimulate the activity of osteoclasts is wrong among the functions of kidneys. The kidneys are two bean-shaped organs in the renal system. They help the body pass waste as urine. They also help filter blood before sending it back to the heart. The kidneys perform many crucial functions, including: maintaining overall fluid balance. regulating and filtering minerals from the blood. filtering waste materials from food, medications, and toxic substances. creating hormones that help produce red blood cells, promote bone health, and regulate blood pressure.

Question 12

Do plant cells have Mitochondria?

Accepted Answer

Yes, plant cells have Mitochondria. While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this. In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize. They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.

Question 13

What are the building blocks of Nucleic Acids?

Accepted Answer

The building blocks of the nucleic acids are "Nucleotides". Each nucleotide are composed of three parts. They are :: 1.Pentose sugar 2.Nitrogenous bases 3.Phosphoric acid.

Question 14

What sugar is found in RNA?

Accepted Answer

RNA - ribonucleic acid is a type of nucleic acid. The sugar contained in it is called Ribose.

Question 15

Which statement about capillaries is correct?

Accepted Answer

Capillaries Tiny blood vessels connecting arteries to veins. These blood vessels carry oxygen and nutrients to individual cells. Capillaries are the smallest blood vessels in the body, and have walls only one or two cells thick. (Their diameter is 5 to 10 micrometers, or 5 to 10 millionths of a meter.) Capillaries connect arterioles and venules, which are the smaller extensions of the larger arteries and veins.

Question 16

In which of the following organelles does photosynthesis take place?

Accepted Answer

Chloroplasts use energy from light to transform carbon dioxide and water into sugar and oxygen. A green pigment located in membranes within the chloroplasts of plants and algae and in the membranes of certain prokaryotes.

Question 17

Which of the following is an Autoimmune disease?

Accepted Answer

An autoimmune disease is a condition in which your immune system mistakenly attacks your body. The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them. Normally, the immune system can tell the difference between foreign cells and your own cells. In an autoimmune disease, the immune system mistakes part of your body — like your joints or skin — as foreign. It releases proteins called autoantibodies that attack healthy cells. Some autoimmune diseases target only one organ. Type 1 diabetes damages the pancreas. Other diseases, like lupus, affect the whole body. Hence, Systematic lupus erythematosus is an autoimmune disease that affects multiple organs.

Question 18

What is the correct order for Respiration?

Accepted Answer

Glycolysis – Krebs’ cycle – electron transport chain

Question 19

Which statement best describes Arteries?

Accepted Answer

Because arteries have to have thick walls for use of protection. Its when you get to veins where the walls get thinner. And the use of the heart is to pump blood to all of the cells and organs in the body so it would be to transport blood away from the heart. i.e. Arteries = Away from the Heart Veins = Back to the Heart.

Question 20

The First step of Bacterial Replication is

Accepted Answer

The First step of Bacterial Replication is DNA Replication. DNA must be copied in order to proceed.
