Moving material along certain gradients is necessary for osmosis, diffusion, filtration, and the transport of ions away from similar charges.
Osmosis is the flow of solvent molecules over a semi-permeable membrane from an area of lower concentration to a region of higher concentration Molecules diffuse when they travel from one area of higher concentration to another area of lower concentration The process of filtering involves moving liquid substances through a separating material known as a filter in order to separate solid particles from liquid. Due to the difference in pressures between the solid and liquid substances, this process is made feasible. Because of the difference in electrical potentials between the charges, ions move away from like charges.

Answer:
Polar Zones - Coldest Temperature
Temperate Zones - Moderate Temperature
Tropical Zones - Hottest Temperature
Explanation:
The closer you are to the Equator, the hotter it gets, as the sun hits the middle of the Earth the most. At the poles, the sun hits it there the least, so it is the coldest. In between, we would have a mild between hot and cold.
*Remember that the Earth is at a tilt, and that is why we have seasons and why the Equator is so hot and the Poles are so cold.
Answer:
0.24M
Explanation:
The equation for the reaction is given below:
H2SO4 + 2KOH → K2SO4 + 2H2O
From the equation above, we obtained the following information:
nA (mole of acid) = 1
nB (mole of base) = 2
Data obtained from the question include:
Va (volume of the acid) = 12mL
Ca (concentration of the acid) =?
Vb (volume of the base) = 36mL
Cb (concentration of the base) = 0.16 M
The Ca (concentration of the acid) can be obtained as follow:
CaVa/CbVb = nA/nB
Ca x 12 / 0.16 x 36 = 1 /2
Cross multiply to express in linear form as shown below:
Ca x 12 x 2 = 0.16 x 36
Divide both side by 12 x 2
Ca = 0.16 x 36/ 12 x 2
Ca = 0.24M
Therefore, the concentration of the acid is 0.24M
An independent variable is the variable that is changed or controlled in a experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured. so like is math. the input variable is the independent variable. the output is the dependent variable because it depends on the input variables.
