52 million miles

• C.

C. 93 million miles
Explanation
The sun is 93 million miles away from the Earth. This is the average distance between the two celestial bodies and is known as an astronomical unit (AU). The distance is so vast that it takes light approximately 8 minutes and 20 seconds to travel from the sun to the Earth. This distance is crucial for various scientific calculations and understanding of space and celestial objects.

### What does it mean by a black hole?

• A.

It is an area in space where the matter has collapsed in itself.

• B.

It is when sunlight stops reaching Earth.

• C.

The dark part of the moon is called a black hole.

• D.

None of these.

A. It is an area in space where the matter has collapsed in itself.
Explanation
A black hole refers to an area in space where matter has collapsed in on itself. This collapse creates an extremely strong gravitational pull that not even light can escape from. As a result, black holes appear as "holes" in the fabric of space, absorbing everything that comes within their event horizon. This explanation accurately describes the concept of a black hole and distinguishes it from the other options provided, which are incorrect or unrelated.

Explanation
A scientist who studies the body is called a physiologist. Physiologists specifically focus on understanding the functions and processes of living organisms, including the human body. They study how different systems within the body work together to maintain homeostasis and carry out various biological functions. By studying physiology, scientists can gain insights into how the body functions in both health and disease, which can ultimately lead to advancements in medicine and healthcare.

### Which one of these is not a planet?

• A.

Earth

• B.

Pluto

• C.

Mars

• D.

Saturn

B. Pluto
Explanation
Pluto is not considered a planet anymore because in 2006, the International Astronomical Union (IAU) redefined the definition of a planet. According to the new definition, a planet must clear its orbit of other debris, and Pluto does not meet this criterion as it shares its orbit with other objects in the Kuiper Belt. Therefore, Pluto is now classified as a dwarf planet.

The given list consists of different organisms, namely fungus, snake, water, and fish. While fungus, snake, and fish are living organisms, water is not a living organism. Water is a substance that is essential for the survival of living organisms, including fungus, snake, and fish. Therefore, water is the correct answer as it is the only non-living entity in the given list.

### How can fishes breathe underwater?

• A.

Because they have filters in their eyes.

• B.

Because they don't need oxygen.

• C.

Because they have gills.

C. Because they have gills.
Explanation
Fishes are able to breathe underwater because they have gills. Gills are specialized organs that extract oxygen from water, allowing fishes to extract oxygen and release carbon dioxide. These gills are located on the sides of their heads and are made up of thin filaments that have a large surface area. As water flows over the gills, oxygen is extracted and absorbed into the bloodstream, while carbon dioxide is released. This process allows fishes to obtain the necessary oxygen for their survival in an aquatic environment.

### Animals can survive without direct contact with which one of these?

• A.

Fire

• B.

Water

• C.

Air

• D.

Food

A. Fire
Explanation
Animals can survive without direct contact with fire because fire is a source of heat and energy, but it is not essential for their survival. While animals may interact with fire in certain situations, such as wildfires or controlled burns, they do not rely on it for their basic needs like water, air, and food. Fire can be dangerous and harmful to animals, causing injury or death, so they have evolved to avoid direct contact with it whenever possible.
