Answer:
The bottom one is "evaporation" and the one to the right is "precipitation".
Explanation:
Evaporation is when the sun heats up a body of water and turns the surface water particles into water vapor. The water vapor then goes into the air and turns into clouds. Precipitation is basically rain.
Answer:
In the muscles during exercise.
Explanation:
During exercise, the body uses up all its oxygen. Therefore, the muscles use anaerobic respiration (making energy w/o oxygen) to function. Lactic acid is produced as a by-product, which makes the muscles sting.
Answer:
1.The cell membranes main trait is its selective permeability, which means that it allows more substances to cross it easily, but not others. small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion but ions (charged molecules) and larger molecules typically cannot.
2. The structure is called a lipid bilayer because it is composed of two layers of fat cells organized in two sheets. the lipid bilayer is typically about five nanometers thick and surrounds all cells providing the cell membrane structure.
3. Osmosis.osmosis is the movement of water across a membrane from an area of low solute concentration to an area of high solute concentration.
4. Active transport. during active transport substances move against the concentration gradient, from an area of low concentration to an area of high concentration. this process is active because it requires the use of energy (usually in the form of ATP). it is the opposite of passive transport.
