Multiple Choice Questions

Question 1.
Which of the following parts of our body help us in movement?
(i) Bones
(ii) Skin
(iii) Muscles
(iv) Organs
Choose the correct answer from the option below.
(a) (i) and (iii)
(b) (ii) and (iv)
(c) (i) and (iv)
(d) (ii) and (iii)
(a): Bones form the structural framework of body called skeleton. The skeleton along with muscles, helps our body parts to move. Muscles are like elastic bands which are attached to the bones by means of tough connecting bands called tendons. The muscles move the bones by their pull. Muscles cannot push. Therefore, to move the bone in one direction, at least two sets of muscles are required. A pair of two types of muscles help the bone to move. One of them contracts and becomes shorter, stiffer and thicker. This pulls the bone in one direction. The other muscle of the pair relaxes when one contracts. To move the bone in the opposite direction, the relaxed muscle contracts itself and brings the bone back to its original position. This time, the first muscle is relaxed.

Question 2.
Which of the following joints is immovable?
(a) Shoulder and arm
(b) Knee and joint
(c) Upper jaw and skull
(d) Lower jaw and upper jaw
(c): Upper jaw and skull has immovable joints. In this type of joints there is no movement between the bones involved. So, these joints are immovable and fixed.

Question 3.
Which of the following organisms does not have both muscles and skeleton for movement?
(a) Dog
(b) Snail
(c) Earthworm
(d) Human being
(None) : Earthworm does not have a skeleton. It has two sets of muscles one that makes it long and thin and the other that makes it fat. The contraction and relaxation of
these muscles help in movement. Snails have exoskeleton and muscles. Human beings and dogs have endoskeleton and muscles.

Question 4.
Underwater divers wear fin-like flippers on their feet to
(a) swim easily in water
(b) look like a fish
(c) walk on water surface
(d) walk over the bottom of the sea(sea bed).
(a): While swimming, the muscle in the front part contracts, generating a curve on one side like a wave and the fin-like flippers move on the opposite direction exerting force against the surrounding water that push the underwater divers forward.

Question 5.
Snail moves with the help of its
(a) shell
(b) bone
(c) muscular foot
(d) whole body.
(c) : During locomotion, the muscular foot of the snail comes outside and attaches to the ground. It forms a series of a wave like motion which helps the snail move forward. The foot of a snail has a special gland that produces a slimy mucus to make slippery track to help it move smoothly.

Question 6.
How many muscles work together to move a bone?
(a) One
(b) Two
(c) Three
(d) Four
(b): Two

Question 13.
Boojho fell off a tree and hurt his ankle. On examination the doctor confirmed that the ankle was fractured. How was it detected?
Doctor must have observed a swelling in the injured area and taken an X-ray of the ankle. X-ray images show the shapes of the bones in our body. By looking at the x-ray, doctor could have confirmed fracture in the ankle.

Question 14.
Bones are hard structures and cannot be bent. But, we can still bend our elbow, knee, etc. How is this possible?
Bending of our body parts such as elbow, knee, back etc. is possible due to the presence of different types of joints between the bones. Elbow and knee are not made up of a single bone but two or more bones which are joined to each other by hinge joint. This joint along with the muscles help us to bend the elbow and knee.

Question 15.
Which type of movement would have been possible if
(a) our elbow had a fixed joint.
(b) we were to have a ball and socket joint between our neck and head.
(a) Only those types of movements are possible which can be done without bending our arm like pointing to something etc.
(b) We would be able to rotate our head at 360°.

Question 16.
Earthworms are known as ‘farmer’s friends’. Why?
Earthworms are called ‘farmer’s friends’. They improve the texture of soil. By burrowing into the soil, they make it loose, thus allowing air to enter into it and water to drain from it. They also form channels in the soil for roots to spread through. Earthworms also increase soil fertility by excreting the undigested materials into the soil.

Question 18.
How is the skeleton of a bird well-suited for flying?
Following features make the skeleton of a bird well – suited for flying :

  1. Shape of the body is streamlined which helps to move in air.
  2. Bones are hollow and light.
  3. Bones of forelimbs are modified into wings for flight.
  4. Bones of hindlimbs are specialised for walking, hopping and perching.
  5. Shoulder bones are strong.
  6. Breastbones hold flight muscles and are used to move the wings up and down.

Question 19:
In the figure given below, there are two snakes of the same size slithering on sand. Can you identify which of them would move faster and why?


Snakes do not have limbs but have rough scales on the underside of the body that help them in their locomotion. A snake form loops in its body while slithering. Each loop of the snake gives it a forward push by pressing against the ground. The snake with a larger number of loops will move much faster than the snake with lesser number of loops.
Thus, snake A will move faster than snake B as we can see more loops are formed by snake A.
