Explanation:
Uses/Advantages of Renewable Energy
It can be used to generate electricity e.g. hydro energy
It is used for cooking at homes e.g. wood/biofuel.
It enables the growth of our crops e.g. solar energy.
It facilitate movement of people and goods from one place to another e.g. fuel, diesel, natural gas.
Renewable energy lasts a life time
Renewable energy is clean and does not cause pollution
Renewable energy is cheap once it is fully installed
Misuses/Disadvantages of Renewable Energy
It can be used to produce nuclear weapons e.g. atomic bomb
It can cause flooding through overflowing of dams
Wind can be disastrous e.g. storms
The ovaries contain the female gamete cell, called the oocytes. In non medical terms, the oocyte is called the “egg”. The ovaries are filled with follicles. Follicles are fluid-filled structures in which the oocyte (also called egg) grows to maturity.
Answer:
nuclei, mitochondria and chloroplasts
I believe the correct answer is the second option, or b.
Buffers such as bicarbonate buffer, citrate buffer and phosphate buffer are important in living system. pH of blood is near to neutrality (7.4). If the pH of blood increases, these buffers help in maintaining the blood pH. Increase in blood pH leads to certain diseases such as alkalosis. This further leads to muscle spasm and respiratory diseases.
Bicarbonate buffer helps to maintain the blood pH if it falls towards acidic range or increases towards alkalinity. It helps in decreasing acidity and increasing alkalinity by forming carbon dioxide gas. Increase in blood pH towards alkalinity is also maintained by excreting the bicarbonates into the urine. Similar action is also seen in case of phosphate buffer and citrate buffer.
Answer: If these buffers are not present in a living system then the change of pH cannot be altered or put back to normal. These buffers help to maintain the pH of the living system so that cells can work properly.
