### What causes motion?

• A.

Force

• B.

Friction

• C.

Mass

• D.

Weight

A. Force
Explanation
Force is the correct answer because it is the fundamental factor that causes motion. Force is defined as a push or pull that can change the state of motion of an object. When a force is applied to an object, it can cause it to start moving, stop moving, or change its direction or speed. Without force, an object would remain at rest or continue moving in a straight line at a constant speed. Therefore, force is the primary cause of motion.

### What is the force per unit area?

• A.

Pressure

• B.

Volume

• C.

Density

• D.

Mass

A. Pressure
Explanation
Pressure is defined as the force per unit area. It is the amount of force applied to a given area. Pressure can be calculated by dividing the force applied by the area over which it is applied. Therefore, pressure is the correct answer for the force per unit area.

### What is the hardest known substance?

• A.

Graphite

• B.

Steel

• C.

Diamond

• D.

Calcium

C. Diamond
Explanation
Diamond is the hardest known substance because of its unique crystal structure and strong covalent bonds between carbon atoms. It has a high hardness rating on the Mohs scale, which measures a material's resistance to scratching. Diamond's hardness allows it to cut through other materials, making it ideal for industrial applications such as cutting, grinding, and drilling. Its exceptional hardness is also why diamonds are used in jewelry, as they can withstand everyday wear and tear without getting easily scratched or damaged.

### Which of these elements helps in bone formation?

• A.

Hydrogen

• B.

Boron

• C.

Calcium

• D.

Nitrogen

C. Calcium
Explanation
Calcium is an essential element that plays a crucial role in bone formation. It is the most abundant mineral in the human body and is required for the development and maintenance of strong and healthy bones. Calcium provides the necessary structural support to bones and teeth, and it also helps in the proper functioning of muscles and nerves. Inadequate calcium intake can lead to weak bones, increased risk of fractures, and conditions like osteoporosis. Therefore, calcium is a key element in promoting bone health and formation.

### What is the deficiency of Vitamin C?

• A.

Perosis

• B.

Beri Beri

• C.

Scurvy

• D.

Night Blindness

C. Scurvy
Explanation
Scurvy is a deficiency of Vitamin C. Vitamin C is essential for the synthesis of collagen, a protein that helps in the formation of connective tissues and wound healing. When there is a deficiency of Vitamin C, the body is unable to produce enough collagen, leading to symptoms such as fatigue, weakness, joint pain, gum disease, and slow wound healing. Scurvy is commonly associated with sailors in the past who did not have access to fresh fruits and vegetables, which are rich sources of Vitamin C.

### Which of these is a bone?

• A.

Aorta

• B.

Villi

• C.

Femur

• D.

Pon

C. Femur
Explanation
The femur is a bone in the human body. It is the longest and strongest bone, located in the thigh. It plays a crucial role in supporting the body's weight and facilitating movement. The aorta, villi, and pon are not bones. The aorta is the main artery that carries oxygenated blood from the heart to the rest of the body, villi are tiny finger-like projections in the small intestine that aid in nutrient absorption, and pon is not a recognized anatomical term.

### What organ controls all the transport system of the body?

• A.

Heart

• B.

Kidney

• C.

Brain

• D.

Liver

A. Heart
Explanation
The heart is responsible for pumping blood throughout the body, delivering oxygen and nutrients to the cells and removing waste products. It is the central organ of the circulatory system, which is responsible for transporting substances such as oxygen, hormones, and immune cells to various parts of the body. Without the heart, the transport system of the body would not be able to function properly, leading to organ failure and ultimately death.

Rate this question:

• 8.

### Which of these organ is for smelling?

• A.

Nose

• B.

Eyes

• C.

Skin

• D.

Ear

A. Nose
Explanation
The organ responsible for smelling is the nose. It contains olfactory receptors that detect and interpret different odors. When we inhale, the air carrying the odor molecules enters the nose, and these receptors send signals to the brain, allowing us to perceive and identify different smells. The eyes are for vision, the skin is for touch, and the ear is for hearing.

• A.

Incisors

• B.

Molar

• C.
