Briefly explain how the relationships between specialized sectors of agriculture function.
Explanation:
Here are three specialized sectors of agriculture:
Soil SciencePlant Science andAnimal Science.Soil science: In simple words, this sector involves the study of the soil, knowing its various properties, and to determine how to properly manage soil.
Plant Science: involves the study of plant life in other to improve plant
life.
Animal Science: This sector studies ways to improve livestock production and management, such as formulating nutritious foods for animals and humans.
Their relationship: Soil science improves soil quality needed by plants; next, Plant Science improves the plant's ability to grow on the soil in other to serve as foods for animals; and finally Animal Science improves livestock production. Ultimately, all three sectors are connected together.What is the ratio between driver gear A with 60 teeth and driven gear B with 180 teeth?

What’s one idea you have about how rescue workers can get energy to their electrical devices in these situations?
Answer:
They can get energy to their devices through natural sources of energy like the sun and wind.
Explanation:
When rescue workers are involved in missions, especially those that involve natural disasters, this could limit or totally eliminate their access to energy from electricity grid lines. When this occurs, they can still make use of the natural sources of energy around them, to power up their devices.
Some of these sources of energy include solar energy and wind energy. These natural sources have been known to power up some batteries. So the rescue workers can utilize them to get energy to their electrical devices.
Answer:
They can get energy to their devices through natural sources of energy like the sun and wind.

A third degree burn may look charred and black or dry and white True Fasle
Answer:
True!
Explanation:
The statement "A third-degree burn may look charred and black or dry and white" is true.
What is a third-degree burn?Third-degree burning is extreme burning. It includes the destruction of the epidermis and dermis, the bones, muscles, and tendons beneath third-degree burns may potentially sustain damage.
The burnt area looks scorched or white. Since the nerve endings in the area have been damaged, there is no sensation there. Due to this, third-degree burning causes less pain than second or first-degree burning.
In third-degree burning, the skin becomes black or charred because of the burning of the dermis and epidermis. The skin recovery from this burning takes time because they are totally destroying the skin.
Thus, the statement is true.
