Answer:
<em>The tactic which will be of no help will be A) Increase your demand for green products and services to reduce your carbon footprint.</em>
Explanation:
Increasing demand for green products will require the cutting down of trees for meeting up the needs. Hence, lesser the trees, more will be the carbon dioxide as trees tend to take up carbon dioxide and use it in the process of photosynthesis.
Also, by using green products, our carbon footprint will not be reduced because the amount of carbon dioxide we release will remain the same. Hence, option A is the correct option.
Answer:
The correct answer is osmosis is the movement of water across the membrane;diffusion is the movement of molecules from a higher to lower concentration with or without the presence of membrane.
Explanation:
Diffusion and osmosis are the two most important process of passive transport.Both diffusion and osmosis helps in the movement of water molecules from high water concentration region to region of low water concentration until equilibrium in both sides is reached.
Osmosis needs the presence of a semipermeable membrane to occur.
