The answer would be “C,” a hypothesis. A conclusion occurs after the experiment—based on the hypothesis—while a constant is a scientific variable which remains unaffected throughout the duration of the experiment.
The answer is electron microscope, the magnification can be so high that it can be very expensive, most schools doesnt have them, mostly found in universities or some laboratories. the ones we usually use in home or schools are light microscope
Answer:
The burning of fossil fuels produces gases like sulfur dioxide and carbon dioxide which trap the sun's heat radiations and increase the overall temperature of the Earth. So the answers are A & B.
Explanation:
Global warming is caused by burning fossil fuels. The <em>carbon dioxide </em>produced as a result captures the heat in the surrounding atmosphere and causes a <u>rise in temperature</u>. Recently, it has been observed that the glaciers are melting and each year the net temperature of the core of the Earth is <em>increasing</em>.
The other gas produced is sulphur dioxide which is responsible for the acid rain. The sulphur dioxide combines with water to form sulphuric acid which causes damage to buildings and people. E.g Taj Mahal, in India is getting corroded by acid rain.
They are neither, they do not have the mechanism to ingest or produce food.
The antibiotic was absorbed by the soil and disrupted the balance of the soil. The result was to kill some of the bacteria living in the soil, which were contributing to the growth of the soybeans. There are bacteria which participate in the process of nitrogen fixation, by providing usable nitrogen to the roots of the plants.
