Answer:
Trees maintain the air quality by the process of
Explanation:
Tress removes the carbon dioxide and it adds oxygen which maintains the balance of the gases in the atmosphere, during the process of photosynthesis which maintains the quality of the air we breathe.
Carbon dioxide is removed from the atmosphere by the trees when they perform photosynthesis, which helps to reduce the greenhouse effect which is caused because of the high level of carbon dioxide present.
They also remove the particulates matter present in the air, which maintains the air quality.
Thus these are some ways by which trees help to maintain the air quality.
Answer:
A) research the information using several sources before taking the supplement.
Explanation:
Crude oil is found above natural gas reservoirs.
B.
Crude oil is found next to natural gas reservoirs.
C.
Crude oil is found below natural gas reservoirs.
D.
Crude oil is mixed in with natural gas reservoirs.
Answer: The correct answer is-
C. Crude oil is found below natural gas reservoirs.
Crude oil is a unrefined form of petroleum. Natural gas and crude oil both are nonrenewable sources of energy that are formed by remains of plants and animals that died millions of years back.
Natural gas is lighter as compared to crude oil. So natural gas has lower density as compared to crude oil. Due to this, crude oil is found below the natural gas reservoirs.
Thus, option C) is the right answer.
(2) electrophoresis (4) dissection
Answer:
Option 2
Explanation:
Electrophoresis or in general known as "Gel electrophoresis" is a process by which separates and arranges DNA as per their size. In this process, DNA samples are placed at one end and at the other end electric current is applied. As we know that DNA fragments carry negative charge on them, hence they move towards the positively charged electrode. Also, all the DNA fragments have the same charge on it, therefore the larger the DNA fragment the more negatively charged the DNA is and hence the more rapidly it moves towards the positive electrode.
At the end of the electrophoresis, same-sized DNA fragments arrange themselves in a row.
Hence, option 2 is correct
