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
Clues such as fossils such as bones, footprints, tar, etc, preserved underground helped inform scientists. You can also count how old a tree is when you cut it open and there are some alive for thousands of years so that is a possible way.
Answer:
The climate system is highly complex, as are the human institutions that are affected by and that must respond to climate change. The difficulty of developing sound strategies for responding to climate change, and of building public support for such strategies, stems in part from the inherent complexity of the issue.Explanation:
Answer:
c. increase HDL levels
Explanation:
Cholesterol is carried in blood in two ways, LDL and HDL. Both of them are lipoproteins made of fat and protein. LDL or Low Density Lipoprotein has 50% cholesterol and 25% protein by weight. HDL or High Density Lipoprotein has 20% cholesterol and 50 % protein. LDL carries cholesterol to arteries and deposits it there which is not good for the body. HDL on the other hand removes excess cholesterol from body via liver.
Aerobic exercise increases HDL values and lowers LDL values. It has been shown that exercising regularly can increase HDL level by 6% which is good for the overall health of the body. For maximum effect 30 minutes of moderate exercise should be done 5 times a week.
