Answer:

C. Active transport

Explanation:

When a molecule moves across a semipermeable membrane into a region of higher concentration it is known as active transport. When there no semipermeable membrane then the movement of molecules from higher concentration to lower concentration is known as diffusion. But when there is a semipermeable membrane in between that time its solvent which moves from higher concentration to the lower concentration not solute and the phenomenon is known as osmosis. This is passive transport and occurs naturally so no energy input is required to be provided for this movement to occur. But, active transport is reverse of passive transport. In active transport, the movement of solvent occurs from lower concentration to higher concentration across a semipermeable membrane. Active transport is not a spontaneous process so in order for active transport to occur we are required to provide an energy input from an outside source.

Answer:

The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. The cell is the fundamental unit of structure and function in living things. All organisms are made up of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells. A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one unicellular to many trillions multicellular.        I hope i helped you

A 0.2 M solution of NaCl contains ________ g of NaCl in 1 l of ________.
Maksim231197 [3]

Answer:

11.7 g in 1 L of water.

Explanation:

Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.

It is defined as mol/ L (number of moles per litre).

0,2 M means we have 0,2 mol/ L

In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol

\frac{1 mol NaCl}{58.443 g} = \frac{0.2 mol}{X g}

X= \frac{(0.2 mol x 58.433 g}{1 mol}

X= 11.69 g

The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
