About This Quiz

This ultimate scientific quiz is for the teens, adults, and teachers who seek to offer science as subjects or in need of having little fun in answering the questions it contains. Science is the study of life which covers both the living things and non-living things. Technology serves as a kid brother to science. Enjoy this quiz!

2.

What is the act of responding to stimulus?
- Growth
- Responsiveness
- Irritability
- Nutrition
Correct Answer

A. Irritability

Explanation

Irritability is the correct answer because it refers to the ability of an organism or a cell to respond to a stimulus. This response can be in the form of movement, secretion, or other physiological changes. Irritability allows organisms to adapt and survive in their environment by responding to changes and stimuli.

What is the framework of the body?
- Skeleton
- Bone
- Muscles
- Tendon
Correct Answer

A. Skeleton

Explanation

The framework of the body refers to the structure that provides support and shape. The skeleton is the correct answer because it is the framework made up of bones that support and protect the body's organs and tissues. The skeleton also allows for movement and provides attachment points for muscles and tendons.

Which of these is used in measuring the mass of an object?
- Beam balance
- Spring balance
- Barometer
- Anemometer
Correct Answer

A. Beam balance

Explanation

A beam balance is used in measuring the mass of an object. It consists of a horizontal beam that is balanced on a fulcrum, with pans suspended from each end. The object whose mass is to be measured is placed on one pan, and standard weights are added to the other pan until the beam is balanced. This allows for an accurate determination of the object's mass.

5.

Which of these is not an effect of friction?
- Heat while rubbing hands
- Walking
- Wear and tear
- Vasolidation
Correct Answer

A. Vasolidation

Explanation

Vasolidation is not an effect of friction. Friction is the force that opposes the motion of objects in contact with each other. When we rub our hands together, friction generates heat. Walking involves friction between our feet and the ground, which allows us to move forward. Wear and tear is also a result of friction, as it causes surfaces to gradually degrade over time. However, vasolidation, which refers to the dilation of blood vessels, is not directly related to friction.

6.

What are the young ones of toad called?
- Calf
- Frogs
- Tadpoles
- Kids
Correct Answer

A. Tadpoles

Explanation

Tadpoles are the young ones of toads. They are aquatic larvae that hatch from eggs laid by adult toads. Tadpoles have gills and a tail, and they undergo a process called metamorphosis to develop into adult toads. During metamorphosis, they gradually lose their tails, grow legs, and develop lungs to adapt to a terrestrial lifestyle. Therefore, the correct answer is tadpoles.

7.

Which of these groups does Snail belongs?
- Amphibians
- Arthropods
- Molluscs
- Arachnids
Correct Answer

A. Molluscs

Explanation

Snails belong to the group of Molluscs. Molluscs are a diverse group of invertebrates that typically have a soft body, a muscular foot, and a hard shell. Snails have a soft body protected by a spiral-shaped shell, which is characteristic of molluscs. They are not amphibians, arthropods, or arachnids, as these groups have different characteristics and classifications.

8.

Which of these is a source of lactic acid?
- Citrus
- Grape
- Sour milk
- Vinegar
Correct Answer

A. Sour milk

Explanation

Sour milk is a source of lactic acid because it contains bacteria called Lactobacillus which ferments lactose, the sugar in milk, into lactic acid. This fermentation process gives sour milk its characteristic tangy taste. Lactic acid is commonly used in the food industry as a preservative, flavoring agent, and pH regulator. It is also produced in our muscles during intense exercise, leading to muscle fatigue and soreness.

9.

Which of these is not a bone?
- Scapula
- Femur
- Tibia
- Tendon
Correct Answer

A. Tendon

Explanation

A tendon is not a bone because it is a tough and flexible band of fibrous tissue that connects muscle to bone. It is responsible for transmitting the force generated by the muscle to the bone, allowing movement. In contrast, the scapula, femur, and tibia are all bones. The scapula is the shoulder blade, the femur is the thigh bone, and the tibia is the shin bone.

10.

What causes motion?
- Force
- Density
- Momentum
- Time
Correct Answer

A. Force

Explanation

Force is the correct answer because it is the fundamental cause of motion according to Newton's laws of motion. An object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force. Force can be defined as a push or pull that can change the state of motion of an object. It can accelerate an object, decelerate it, or change its direction. Therefore, force is the underlying factor that causes any kind of motion to occur.
