Answer: Oxygen Isotopes!
Explanation: I just took the quiz and I got it correct!
Larger
During the process of breathing, the diaphragm contract by moving
downward and upward and this process usually increase or decrease the space in
the chest cavity. However, intercostal muscles between the ribs also help to enlarge
the chest cavity or reduce the space in the chest cavity.
Answer: cell membrane
such as water, micro-organism
physical process
simple diffusion, osmosis and filtration
such as potasssium permaganate in water,urea a liver waste diffuses from the body and the kidney help in filtering it out
physiological processs
active transport, phagocytosis and pinocytosis
such as soduim-potassium pump, exocytosis
Explanation: transportation in and out of cell is done in different ways listed above but a barrier to this movement is the cell membrane which is an outer covering of the cell. it protect the cell and only some materials can penetrate the cell membrane e.g micro-organism, water e.t.c. the various physical and physiological processes are the various ways substance cna be liquid, solid or gas are transported within or outside the cell e.g food
Answer:
Gas
Explanation:
Gas molecules are more spaced out, therefore having more room to move. Liquid molecules are closer together, this means it can’t move as much. Solid molecules are as close as they can be, it is very hard or impossible for them to move.
Brainliest please. :)
You can get help structuring it, but you can't get someone to write it if it isn't your thoughts.
