How are particles arranged in a solid?

A solid's volume and shape are fixed, which means the particles are rigid and stay in place. It is not easy to compress a solid, as there is not much space between the particles. As solid particles are unable to move past each other, it is not easy to make a solid flow.Although gases, liquids and solids feature atoms, molecules and sometimes ions as their key components, they have significant microscopic differences. Solid particles vary considerably from liquids. For example, liquid particles have fluidity, which means it is possible to make a liquid flow. In addition, this allows them t..

What are some temperate ocean plants?

Seagrasses thrive in a wide variety of water temperatures, including temperate oceans. Although these plants stay submerged under the water, they can only survive in shallow mid-intertidal zones because they have roots and depend on photosynthesis to survive. The water needs to be shallow enough for the sunlight to reach the leaves on the plants beneath the surface of the water.\nBrown algae is another type of temperate ocean plant, although it can be found in subpolar regions as well. Brown algae must attach to a substrate or another substance, so it is most often found along shores or in sha..

How many micrograms are in a millilitre?

Because micrograms per milliliter is not a standard measurement for density, some conversion may be required to determine the amount of micrograms in a milliliter of a substance. For example, the density of lead is 11.342 grams per milliliter. There are 1 million micrograms in a gram, so there are 11,342,000 micrograms in 1 milliliter of lead. On the other hand, the density of methyl alcohol is 0.785 grams per milliliter, which means that there are 785,000 micrograms in 1 milliliter of methyl alcohol.

Why are enzymes important?

Humans have metabolic enzymes which are responsible for the chemical processes in the body. They control everything from thinking to breathing.Digestive enzymes digest everything a person puts into his or her body. There are 22 known enzymes that digest carbohydrates, proteins, fats and sugars.Plant enzymes are only available in raw plants and are destroyed during the cooking process. These plant enzymes help the body continually produce other types of enzymes.Enzymes are necessary for every function of the human body from breaking down food to producing hormones. Several aspects of everyday l..

What is an example of a raised flat area?

Plateaus are also called tablelands. They can be formed by numerous natural processes, including the extrusion of lava, erosion caused by glaciers and water, and flowing volcanic magma.\n\nPlateau is derived from the Middle French word platter, meaning flat. Its first known use was in 1796.\n\nThe world's highest and largest plateau is the Tibetan Plateau, also called "the roof of the world." It covers approximately 970,000 square miles and is about 16,000 feet above sea level.
