Answer:
D. x2000
Explanation:
magnification = image(drawing size)/actual size
magnification = 40/0.02
magnification = x2000
Answer: False
Explanation: Red blood cells placed in a solution with a higher water concentration compared to their contents will gain water by osmosis, swell up and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.
One way of controlling insect pests in an apple orchard without using any chemical pesticides is by using neem oil from the neem tree. The use of the oil interrupts the life cycle of the insect. Also, using compost from wood chips and spraying the roots of the tree with a concoction of horsetail and stinging nettles.

Answer:
The correct answer will be option-A
Explanation:
The transport of the molecules between cells and a cell and its surrounding is very important to survive.
A cell has evolved two ways to transport the molecules which are passive and active movement or transport.
The passive movement is the movement of the molecules across the membrane depending on the concentration gradient without using any source of energy which is utilized in active transport.
In the given question, osmosis is the process which can be considered passive movement as it transports the water down the concentration gradient without using any source of water.
Thus, osmosis is the correct answer.
