Not all forms must reproduce to survive
- True
- False
Correct Answer

A. False

Explanation

This statement is false because in order for a species to survive, reproduction is necessary. Reproduction allows for the passing on of genetic material and the creation of new individuals. Without reproduction, a species would not be able to continue its existence over time. Therefore, all forms must reproduce to survive.

Motion of an object is relative to a point of reference
- True
- False
Correct Answer

A. True

Explanation

The statement "Motion of an object is relative to a point of reference" is true. This means that the motion of an object can only be described in relation to another object or point. For example, if a car is moving at 60 miles per hour, this speed is only meaningful when compared to a reference point, such as the speed of another car or the speed limit on the road. Without a point of reference, it is impossible to determine the motion of an object. Therefore, the statement is true.

The warming of the earth by the sun is the major our source of energy
- True
- False
Correct Answer

A. True

Explanation

The explanation for the given correct answer is that the sun is indeed the major source of energy for the warming of the earth. The sun emits electromagnetic radiation, including visible light and heat, which reaches the earth and warms its surface. This solar energy is essential for various processes on earth, such as photosynthesis in plants, weather patterns, and the overall climate. Without the sun's energy, the earth would be a cold and lifeless planet.
