Answer:
Geothermal and Nuclear
Explanation:
Geothermal is the most reliable renewable energies and comes from the Earth. Nuclear energy is actually non-renewable but it is safe and extremely effecient.
Most living things need energy from the Sun. Green leaves on plants use sunlight, air, water, and nutrients to make food. Plants use the food to live and grow. Animals use energy to move and to eat, then letting energy out. It's a natural cycle.
Answer:
a. True.
Explanation:
Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.
Answer:
Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of <u><em> Bioremediation. </em></u>
To rid an area of mosquitoes, biologists introduced a species of fish into bodies of water that feed on the mosquito larvae. This method is an example of <em>Biological Augmentation.</em>
Explanation:
Bioremediation can be described as a process which uses plants or microorganisms to detoxify contaminants that are present in an area. The enzymes of a plant or animal tend to break down the contaminants and hence, we can make an area rid of contaminants in this way.
Biological augmentation can be described as a method by which organisms such as bacteria are introduced in an area to get rid of wastes.
