Question 2

Which system transmits impulses between different parts of the body?

Accepted Answer

A complex network of nerve cells or neurons forms the nervous system. This system is responsible for transmitting electrical impulses throughout the body.So, the correct answer is 'Nervous system'.

Question 3

Excretory organs of Cockroach are

Accepted Answer

Excretion is performed by Malpighian tubules. Each tubule is lined by glandular and ciliated cells. They absorb nitrogenous waste products and convert them into uric acid which is excreted out through the hindgut. Therefore, this insect is called uricotelic. The fat body nephrocytes and urecose glands also help in excretion.So the correct answer is 'Malpighian tubules'.

Question 4

Which is absent in blood of Cockroach ?

Accepted Answer

The cockroach has an open vascular system consisting of sinuses filled with blood. The blood of cockroach is without haemoglobin or any other respiratory pigment. This type of blood devoid of any respiratory pigment is called haemolymph.So, the correct answer is 'Respiratory pigment'.

Question 5

Earthworm has no skeleton. During burrowing anterior end becomes turgid and acts as hydraulic skeleton. It is due to

Accepted Answer

The earthworm has no skeleton but during burrowing, the anterior end becomes turgid and acts as a hydraulic skeleton. It is due to coelomic fluid. The coelom is filled with alkaline, milky coelomic fluid. So, the correct answer is 'Coelomic fluid'.

Question 6

In leg of Cockroach, trochanter is followed by

Accepted Answer

There are three pairs of walking legs in the cockroach. Each leg is formed of 5 podomeres. The arrangement of podomeres is as follows: Coxa, Trochanter, Femur, Tibia and Tarsus. So, the correct answer is 'Femur'.

Question 7

Chloragogen cells are

Accepted Answer

The chloragogen cells are also called as 'y-cells'. These cells in annelids are functionally similar to liver of vertebrates. These cells undertake many functions. They store glycogen and also neutralize toxins. They also take part in deamination of amino acids and synthesise urea.So, the correct answer is 'Polyfunctional'.

Question 8

A detrivorous animal of economic importance is

Accepted Answer

Earthworms eat decaying plant and animal matter in the soil. They are classic examples of detritivores because they consume organic material from the soil. Leech feeds on blood. Fowls feed on seeds and insects and caterpillar larva on leaves. As earthworm is detritivorous, it is used in the preparation of compost. So, the correct answer is 'Earthworm'.

Question 9

The fibrous tissue which connects the two bone is

Accepted Answer

Connective tissue is a type of tissue in which cells are loosely spaced and embedded in a rigid, jelly-like, fluid matrix.Tendon is a fibrous tissue connecting muscle to bone.Adipose tissue is fat-storing tissue, which is present below the skin and between internal organs. A ligament is a fibrous tissue connecting bones to other bones. Therefore, option C is correct.

Question 10

A tendon connects a .......... to a ..........

Accepted Answer

Explanation:Tendons are fibrous connective tissues that connect skeletal muscles to bones.Tendons are involved in limb movements and prevent muscle injury during strenuous work.
