Answer:
Option B = Lipids
Explanation:
Lipids include waxes, fats, steroids and oils. These are found in both eukaryotes and prokaryotes. Lipids play important role of energy storage, membrane formation, cell division and protection.
Structure of lipids:
Lipids are made up of triglyceride which are further consist of fatty acids and alcohol glycerol. Because of great diversity more than 10,000 lipids are discovered. Lipids are smaller than the protein.
Example:
Fatty acids are the lipids and act as a building blocks for other kind of lipids. The carboxyl group (-COOH) in fatty acids attached to the carbon chain trough attached hydrogen and make the chain water soluble. There are two kinds of fatty acids saturated and unsaturated. The saturated fatty acid has single bonds and unsaturated fatty acids have double bonds. The unsaturated fatty acids yield oils when combine with triglycerides.
Function of lipids:
Lipids play important role in organism. Some are important roles are given below:
1. They make protective barrier.
2. They take part in the formation of cell wall of plants and cell membrane.
3. They are also act as an energy storage device.
4. They take part in the formation of Golgi apparatus, nuclear envelop and other cellular compartments.
5. They provide the insulation against harsh environment to the vital organs
In this experiment, they want to test the effect of each wax, with the question being "which wax protects the floor the most from scratches?" or "with which wax does the floor has the least scratches?"
The independent variable depends only on itself and is not affected by others, in this case, it would be the type of wax (expensive, cheap, none).
The dependent variable is the one that would change with the independent variable, in this case, the number of scratches.
The constants would be things that don't change, in this case, the size of the sections, and the kind of tiles.
Conservation biology uses ecological information to restore damage in our ecosystem. Ecological information gives us ideas on how to prevent or restore our ecosystem by doing practices that can help ease the pollution and damages.<span />
When individuals in a population are unevenly spaced throughout their habitat, their dispersion was most likely random dispersion.
Habitat in simple terms is the place where an organisms lives. An organism carries out all its life activities in that area. These activities include eating, living, mating and reproduction. An organism's habitat must contain all the essential resources for it to survive efficiently.
Random dispersion is the type where the organisms are distributed randomly without any fixed pattern. These are a little rare to see in nature. The example of random dispersion is the dispersal of seeds from wind, they can spread in any direction.
