Answer:
No
Explanation:
Electromagnetic waves travel slowest in dense matter such as solids. On the other hand, mechanical waves travel quickly through solids. For example, sound travels fastest through solids. This difference is because EM waves do not rely on the movement of particles to travel. Since they require no medium they can travel the fastest in space or other vacuums.
Water (H
2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" [17][18] and the "solvent of life".[19] It is the most abundant substance on Earth[20] and the only common substance to exist as a solid, liquid, and gas on Earth's surface.[21] It is also the third most abundant molecule in the universe.[20]
Temperate environment have the best soil in the world because of higher nutrient levels.
<h3>What is soil?</h3>
Soil is the topmost layer of the earth on which plants grow.
Types of soil include:
- loamy soil
- sandy soil
- clayey soil
The best soil for plant growth is loamy soil because it contains the most nutrients.
Temperate environment have the best soil in the world because of higher nutrient levels.

Answer:
A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. A hypothesis must be testable and measurable. This means that researchers must be able to carry out investi- gations and gather evidence that will either support or disprove the hypothesis.
Explanation:
The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
