<u>Answer:</u>
<em>lightening breaks</em><em> down the nitrogen molecules and provide a suitable environment to mix with oxygen (high temperature and pressure). </em>
<em>When these mix with water, the nitric acids are obtained which dissolves in soil and plants can use those </em><em>nitric acids for growth and development.</em>
<u>Explanation:</u>
The role of bacteria in nitrogen cycle is it breaks down the protein content in <em>dead plants and animals during decay process</em> and ammonia is formed.
Then the<em> nitrifying bacteria causes nitrification</em> which turns nitrogen into soluble nitrates that the plants can absorb.
Answer:
After C14, Uranium238 is most widely used mineral in geological or archaeological dating.
Explanation:
U238 is generally used to date the rock materials, to know the age. As we know the half-life of U238, it is easy to identify the age of the materials containing uranium 238. It can be called as absolute dating method as it determines the exact age of the uranium contained material. It is a type of radiometric dating.
Answer:
True
Explanation:
Facultative anaerobes are bacteria who used to grow in the aerobic condition but when oxygen becomes deficient they can switch to anaerobic mode and obtain energy through fermentation. So facultative anaerobe normally lives in aerobic condition but can survive in anaerobic conditions too.
So as facultative anaerobes normally grows in aerobic condition they grow well in incubator shelf but in anaerobic condition like anaerobic jar or in a candle jar they will show moderate growth because it is not the ideal condition for them to grow. Therefore the statement is true.
