<u>Answer:</u>
Considering the nitrogen cycle, all organisms depend on bacteria to produce and maintain adequate nitrogen in the environment by eating the plants that contain bacteria which contain nitrogen.
Option: (B)
<u>Explanation:</u>
- Nitrogen is a main element in the nucleic acid of both RNA and DNA which is most important for all living creatures and biological molecules.
- When plants doesn’t get enough nitrogen it doesn’t produce amino acid, without amino acid plant cannot make special proteins.
- Amino acid is building block for DNA which tends to the generation of organism.
- Nitrogen fixation is a process where bacteria convert atmospheric nitrogen to usage form for plant and animals get nitrogen by eating those plants.

Explanation:
Heat therapy is said to work because of its analgesic properties or its ability to bring blood to the area which can penetrate deep into the muscular tissue. However, heat therapy is also said to work because it is comforting on a psychological level. According to Lorimer Moseley “to reduce pain, we need to reduce credible evidence of danger & increase credible evidence of safety” and applying heat makes us feel safe. Why? Because the cold kills!
Despite this, there is little evidence to show that it helps alleviate pain at certain trigger points (small patches of acutely sensitive soft tissue) in the body and there is less evidence to show that it works for period pain. One study has claimed that heat can work for period pain however the researchers failed to differentiate if their exercise programme or the psychological effect of feeling warm eased their pain. This kind of testing means that other variables influence participants’ perception of pain and we can’t be certain if the heat therapy actually helped. What we do know is there are certainly drawbacks to this kind of treatment.

<h2>Answer:</h2>
<u>Soil erosion can occur in the area where trees are less</u>
<h2>Explanation:</h2>
As we know that trees have long roots spread into soil to a larger distance. Soil erosion occurs when the soil takes the surface land with it. So if the trees are present there they will keep the soil firm and stop it from sliding. Therefore the erosion can probably occur in the land where there are no trees.
