Explanation

Soil helps plants by providing them with essential minerals. These minerals are necessary for the growth and development of plants. They are absorbed by the plant roots from the soil and used for various physiological processes, such as photosynthesis and nutrient transportation. Without these minerals, plants would not be able to thrive and fulfill their nutritional requirements.

Explanation

The brain is the control center of the body because it is responsible for coordinating and regulating all bodily functions. It receives and processes information from the senses, controls movement, regulates body temperature, and allows for complex cognitive processes such as thinking, memory, and emotions. Without the brain, the body would not be able to function properly or survive.
