Banana peels can be decomposed by bacterial action, so they are biodegradable.
Answer:B is the right answer I am sure.
Explanation:
Answer:
D (Swell and Burst)
Explanation:
Pure water contains a very low concentration of solute materials, hence it is regarded as HYPOTONIC. Since the red blood cell contains intracellular fluid that contains more solutes than the extracellular pure water it is placed in, it is said to be HYPERTONIC in comparison with the pure water.
This difference in concentration between the extracellular solution (pure water) and the intracellular fluid (red blood cell) called CONCENTRATION GRADIENT facilitates the movement of water by OSMOSIS. Osmosis is the process whereby water moves across a semi-permeable membrane from a region of low solute concentration to a high solute concentration.
Based on this osmotic gradient, water moves from the extracellular solution into the cell, causing it to swell and eventually burst as a result of excessive water intake.
Lichens and mosses are usually the pioneer plants that are found on barren lands. The two have the ability to survive in this kind of environment because of their minimal energy needs. When lichen and mosses died off, they are usually replaced by bigger plants because they have made the place suitable for the growth of larger plants. The dead parts of lichen and mosses decompose and turn into small particles of soil, this allow other plant species to grow in this location.
Answer:
Growing new trees to replace old trees
Explanation:
Growing new trees in place of old ones sustains the environment, since trees help circulate oxygen and provide homes and nutrients for animals and other plants.
Any form of mining is bad for the environment and unsustainable in the long run, garbage is the same way, and putting it on land is only slightly better, and switching to other resources doesn't do anything but burn out more resources and does nothing to sustain anything.
Hope this helps :)
