Explanation:
Answer:
As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas

Question 3
Answer:

During osmosis, water diffuses across a selectively permeable membrane from the region of higher _______ concentration and lower _____ concentration to the side with lower _______ concentration and higher _______ concentration
.
Answer:
During osmosis, water diffuses across a selectively permeable membrane from the region of higher free water concentration and lower solute concentration to the side with lower free water concentration and higher solute concentration
Explanation:
Osmosis is a biological process that takes place in cells and allows a substance to pass through the plasma membrane. Through osmosis, the plasma membrane, water can pass into and out of the cell through a gradient of solute concentration, that is, water passes from the place with the lowest concentration of solute to the place with the highest concentration, allowing thus the balance between the inter and extra cellular medium.
