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.

Is water wet????? Is it or not?
How did animals change to mimic others? this genuinely fascinates me and I want to know how they do it- like- the Viceroy Butterfly mimics the poisonous Monarch Butterfly. but- h o w - did they spend so much time watching the Monarch that they slowly became their look-alikes? how does mimicry happen over time....
my understanding is that they evolve over time, one could say adapt, to survive to mimic other creatures, im sure there are plenty of books you could borrow from a library or buy online to learn more, and there are different studies people have done you might be able to find free online!!!
Answer:
They evolve over time
Explanation:
Animals evolve over time to fit into their surroundings and to survive. This could take several generations though, because change doesn't happen over night. To put it simply, survival of the fittest. They have to fit in in order to survive, so they did exactly that.

What happens when a cell reaches equilibrium with its environment?
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 _-_

Explanation:
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.

Think of a time when you were extremely scared or nervous and experienced an adrenaline rush. Write about your experience below.
One day I was walking down a river with my friends. After a while of walking a 3 feet snake jumped out of the river and scared the living out of us. The snake left but the adrenaline rush made me jump onto a tree without planning to jump on the tree.
Once when I was 9 my friends and I were walking by a pond when we got a bad vibe so we left. While we were walking we spotted a ditch and decided to go and check it out. So when we were there we kept hearing wierd noises but thought it was just some birds or something. (Keep in mind there was a sorta tunnel that went under the road that lead from the ditch to the pond.) So my friend said he saw something in the tunnel and when we looked in the tunnel there was someone there looking back at us so we of the ditch and went to the playground nearby. We haven't gone back since, lol.

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.
