Explanation:
Is a compound is a pure substance?
* I"m just wondering,
Answer:
yes
Explanation:
Compounds: are pure substances that are made up of more than l type of atom and can be broken down or decomposed into its individual elements by chemical methods, but cannot be separated by physical methods. The ratio of the elements in a compound are always constant. (Water is always 11 % Hydrogen and 89 % oxygen).
Answer:
Yes, it is.
Explanation:
Because there's no physical change that can separate compounds into more than one kind of substance.

How did migration lead to the population of the world?
Plant cells use photosynthesis to make the organic compounds that their mitochondria and other organelles need. Where do you think animal cells get these same organic compounds from? How do their cells use these compounds?
The organelles called mitochondria in cells are capable of generating energy. Plants need mitochondria to make ATP from different chemical sources, even though they derive their energy from the Sun.
What organic compound synthesize in animal cell for energy?Cellular respiration, a process that releases energy by mixing glucose and oxygen, is the method that all cells rely on to obtain their energy.
The process of releasing energy from meals takes place inside the body's cells during respiration.
As part of the respiration process, the body's cells absorb oxygen from the air, use it to produce energy by burning food, and then expel the waste materials (carbon dioxide and water) from the body.
Plants use the carbon dioxide exhaled during respiration for the process of photosynthesis. Animals do not use the carbon dioxide produced during breathing; instead, it is expelled outside the body.
Therefore, animal cells get these same organic compounds from cellular respiration.

A.) Nothing enters the cell
B.) Nothing leaves the cell.
C.) Nothing enters or leaves the cell.
D.) Molecules enter and leave the cell at the same rate.
Answer:
D
Explanation:
Even when equilibrium is reached, particles of a solution will continue to move across the membrane in both directions. However, because almost equal numbers of particles move in each direction, there is no further change in concentration. Hope i did it right _-_

What are the benefits of living in a permanent settlement vs. a nomadic settlement? Include at least three benefits.
Answer:
One of the most obvious advantages is being able to grow and harvest crops on land as a result of agriculture, rather than relying on natural landscapes to provide. Another is safety and security — you do not have to traverse potentially dangerous routes and can defend your land from your home. Finally, urban cultural centres are not possible when moving from place to place as you have to take everything with you. Permanent settlement allows advanced civilisations to develop.
