What process does a cell with a low concentration of oxygen will likely gain oxygen molecules from an area with a higher oxygen concentration have to go through?
Diffusion.
Hydrogen molecules and oxygen molecules can be easily split by what?
Hydrogen molecules and oxygen molecules can be easily split by what electrolysis. This is the process which is used to breakdown water.
What process uses oxygen to break down food molecules?
osmosis
Do molecules spread out when heated?
Yes, ok take a block of ice for an example, when the water is frozen into the ice cube the molecules slow downcget closer and they can't move, when you melt the ice, or it is heated, then the molecules spread out and get faster making it a liquid.
Use the sun to make energy rich molecules?
The process in which the sun is used to make energy rich molecules is called Photosynthesis. This process uses carbon dioxide, water and energy collected from the sun, to produce glucose molecules and oxygen gas. This process happens in plants and is the plant's main source of energy.
What process does a cell with a low concentration of oxygen will likely gain oxygen molecules from an area with a higher oxygen concentration have to go through?
Diffusion.
When molecules such as oxygen are moved into Cells along their concentration gradient directly through the Cell membrane - this is called?
Trans-membrane diffusion.
How are oxygen and carbon dioxide exchanged in the Lings and though all cell membranes?
They enter/exit through a passive transport process called diffusion. It is caused by a concentration gradient within the two things being exchanged. The molecules diffuse across the membrane from the high concentration to the lower concentration side.
How does oxygen get in and out of plasma membrane?
Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
How would the concentration of ozone molecules change if the concentration of oxygen molecules decreased?
If oxygen decreased, ozone will decrease. It is because ozone is made from oxygen.
How does oxygen get out of the leaf cells and back into the air outside the plant?
Through a process called diffusion. This process is the random movement of molecules from an area of high concentration to an area of low concentration.
Why does oxygen diffusion from the alveolus to the alveolar capillary occur?
Diffusion (of anything) occurs because of a concentration gradient meaning there is more oxygen in one place than another. Alveolus when you inhale will have a higher concentration of oxygen that that of the alveolar capillary resulting in a concentration gradient, this causing diffusion to occur until equilibrium is met. This means more oxygen in alveolus so oxygen travels into the alveolar capillary until a balanced amount of oxygen is in both places, but then of course the oxygen is transported and you exhale and inhale so the process repeats.
How is oxygen taken in into the body tissue?
At the level of the capillaries, oxygen will diffuse out of the saturated red blood cells down their concentration gradient into the tissues where their concentration is lowest.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
What types of transport moves molecules along a concentration gradient?
I'm not sure you're understanding the question you are asking. Molecules are the tiny building blocks, made up of atoms, that are used to create everything in our galaxy. Cells are a single living unit that work together to be a living thing. If you are interested in how parts of a cell move around or pass along material, you should look up how cells work or ask a more specific question.
What direction will oxygen diffuse?
Diffusion is when a molecules spread from an area of high concentration to an area of low concentration so the oxygen will move away from the other oxygen molecules that were in a high concentration to an area with a lower concentration. An example you would relate this to would be if you were to put a drop of food coloring into a glass of water.
What is the process called within the amoeba for which oxygen is required?
It enters through the lipid bilayer (aka cell membrane) by diffusion down a concentration gradient from a high concentration to a low one. This process is continuous. Diffusion occurs naturally because of the kinetic energy in the oxygen particles which allows them to move - this is known as Brownian Motion.
