1) 35mL to L 1 L = 1000ml so, 35mL = 35÷1000=0.035L
2) 950gm = 1Kg =1000g SO, 950÷1000= 0.950 Kg
3) 275mm to cm= 1mm= 1÷10 cm so, 275÷10= 27.5cm
4)1000mL to L = 1L=1000ml so, it will equal to 1L
5)4500mg to g = 1mg= 1÷1000g so, it will equal to 4.5g
6)25cm to mm = 1cm= 10mm so, 25X 10= 250mm
7)0.005Kg to mg, so 1Kg= 10∧6 mg so, 0.005X10∧6= 5000mg
8)0.075m to cm, so 1m =100cm so, 0.075X100= 0.75cm
9)15 g to mg , so 1g = 1000mg so, 15X1000= 15000mg
Answer:
The correct answer is b) When a plant cell is placed in concentrated salt water, water moves out of the cell.
Explanation:
Osmosis is the movement of solvent molecules from an area of less concentration of solute to high concentration of solute to equalize the concentration of both the side of the cell.
So water will move outside the cell when any cell will be placed in a concentrated salt water because the concentration of solute is high in salt water and low inside the cell.
Therefore when a plant cell is placed in salt water the osmosis of water takes place from inside to outside the cell. So the right answer is b.
