Weekly Quiz Competition

Question 1
1 / -0

Which of the following is the most complex joint?

A
Freely movable

B
Immovable

C
Partially movable

D
All of the above

Solution

Freely movable joints are the most complex of the joints. Freely movable joints come in different shapes and allow different movements. Six types of freely movable joints exist. The ball-and-socket joint, of which the shoulder is an example, has a ball-shaped head and allows the widest range of motion. The elbow is a hinge joint and is able to move in only one plane etc. Therefore, (a) is the correct answer.
Question 2
1 / -0

The filaments of myofibril are made up of

A
Actin, troponin, tropomyosin

B
Actin, troponin

C
Myosin, troponin

D
Actin, tropomyosin

Solution

Myofibrils are the contractile fibres that are present in the striated muscles and are also called as the muscle fibres. They are composed of the thick and thin filaments called the actin and myosin along with the troponin and tropomyosin muscle proteins.
Question 3
1 / -0

Which of the following would ensure healthy joints?

A
Playing outdoor games

B
Playing indoor games

C
Eating more red meat

D
Use of massage oil

Solution

Walking and playing in fresh air keeps the body fit and healthy. One must also have a balanced diet and maintain a healthy body weight.
Question 4
1 / -0

The external or internal framework which provides support to the body is called __________.

A
Supportive chord

B
Tendons

C
Skeleton

D
Muscles

Solution

The external or internal framework which provides support to the body is called skeleton. It is of two types exoskeleton and endoskeleton. The lower group and animals possesses only exoskeleton for protection e.g. Cockroach while higher animals possess both e.g. Fish.
Question 5
1 / -0

Locomotion is ________.

A
Voluntary movement

B
Involuntary movement

C
Nastic movement

D
Either A or B
Solution
- Locomotion in biology pertains to the various movements of organisms (single-celled or multicellular organisms) to propel themselves from one place to another.
- In multicellular animals, these movements include walking, running, jumping, crawling, climbing, swimming, flying, galloping, slithering, and so on. Voluntary muscles are the ones that we can control.
- Most of them move the bones around. If we want to run, walk, ride a bike, wave our arms around, or eat our favorite sandwich, it is voluntary muscles by which we can move arms, legs, and body around. Hence, locomotion is a voluntary movement.
So, the correct answer is 'Voluntary movement'.
Question 6
1 / -0

Select the correct statement.

A
All locomotion are movement but all movements are not locomotion.

B
All movements are locomotion but all locomotion are not movement.

C
All locomotion are different from all movements.

D
All of the above.
Solution
- Locomotion occurs when a body changes its position from one place to another.
- Walking, running, climbing are the forms of locomotion.
- But some movements of our body parts like the tongue, jaws does not result in any locomotion.
- Thus it can be said that all locomotions are movements but all movements are not locomotion.
Hence, the correct statement is "All locomotion is movement but all movements are not locomotion".
Question 7
1 / -0

Which of the following is the result of synthesis of actin molecule(coded by allele) in a linear chain?

A
Immovable muscles

B
Smooth muscle tissue

C
Normal sarcomere structure

D
Degeneration of muscle tissue

E
Muscle tendons that cannot attach
Solution
A sarcomere is the functional unit (contractile unit) of a muscle fibre.
Each sarcomere contains two types of myofilaments: thick filaments, composed primarily of the contractile protein myosin, and thin filaments, composed primarily of the contractile protein actin. Hence, Normal sarcomere structure is the result of the synthesis of actin molecule(coded by allele) in a linear chain.
So, the correct answer is 'Normal sarcomere structure'.
Question 8
1 / -0

What would be the result of an allele that codes for all actin molecules to be synthesized in linear chains?

A
Immovable muscles

B
Smooth muscle tissue

C
Normal sarcomere structure

D
Degeneration of muscle tissue

E
Muscle tendons that cannot attach

Solution

Sarcomere is the structural and functional unit of a myofibril and consists of thick myosin filaments and thin actin filaments. If the allele for actin filament continues to synthesize linear chains of the protein, sarcomere structure would be same as normal. Thus, the correct answer is option C.
Question 9
1 / -0

An example of amoeboid movement is

A
Limbs

B
Leucocytes

C
Trachea

D
None of the above
Solution
Movement is a characteristic feature of living organisms. The different types of movement exhibited by cells of the human body are:
Amoeboid movement: Leucocytes present in the blood show amoeboid movement.
Ciliary movement: Reproductive cells such as sperms and ova show ciliary movement.
Muscular movements: Muscle tissue found inside of the heart, digestive organs, and blood vessels serve to move substances throughout the body. Hence, An example of amoeboid movement is Leucocytes.
So, the correct answer is 'Leucocytes'.
Question 10
1 / -0

In amoeboid movement, according to Goldacre and Lorsch cytoplasm solates due to

A
Sliding of actin molecules

B
Sliding of myosin molecules

C
Unfolding of protein molecules

D
Folding of protein molecules

Solution

The cytoplasm inside the cell is capable of changing into different forms i.e., from fluid to solid and vice versa. When the cytoplasm is in fluid state, it is known as plasma sol, and the more solid or gel like state is called the plasmagel. The plasmasol changes into rigid plasmagel (gelates) at the anterior end and at the posterior end the plasmagel changes into plasmasol (solates) causing a forward streaming of the more fluid plasmasol). The interchange of plasma sol to plasmagel is known as Sol-Gel theory and is responsible for amoeba movement. It was explained by Goldacre and Lorsch.
Therefore, the correct answer is option A.
