Why is transpiration an important process in a plant? It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, […]

How do you know what angle to cut? The formula involves dividing 360 by the number of sides to calculate the corner angle. Then divide it by two to get the miter angle. If you’re making a five-sided project with all sides equal, you divide 360 by five to get 72 degrees. So each joint […]

What are the three types of buoyancy? What are the three types of buoyancy? The three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy. Positive buoyancy is when the immersed object is lighter than the fluid displaced and this is the reason why the object floats. How do you pronounce Euclid’s? Wiki […]

What will happen if you pour hot water to the metal lid on the closed jar? Applied to a metal jar lid, this implies that the inside diameter of the lid will increase, tending to loosen the lid. Directing the stream of hot water at the center of the lid heats the metal more than […]

Which region has many mountain ranges separated by desert basins? Great Basin physiographic section The Basin and Range region is the product of geological forces stretching the earth’s crust, creating many north–south trending mountain ranges. These ranges are separated by flat valleys or basins. These hundreds of ranges make Nevada the most mountainous state in […]

Can we prove axioms? Unfortunately you can’t prove something using nothing. You need at least a few building blocks to start with, and these are called Axioms. Mathematicians assume that axioms are true without being able to prove them. If there are too few axioms, you can prove very little and mathematics would not be […]
