One difference between mechanical and electromagnetic waves is that mechanical waves need a medium to pass through (solid, liquid, gas). EM waves can travel through matter or though a vacuum. In regards to telecommunications, EM waves can be radio waves, these are used in TV's, phones, computers, radios. Mechanical waves somewhat relate to this since radios produce sound;so an EM wave would turn into a mechanical vibration inside a speaker then sound would be produced.
Nitrogen is present in the environment in abundance but still we cant inhale nitrogen
<h3>
What is the role of nitrogen in our body?</h3>
Nitrogen is physiologically inert. It contributes nothing to the functioning of our bodies. The cells in our body need oxygen to live, not nitrogen. we can find nitrogen in our body in form of nitrogeneous base in nucleotide.
We inhale all gases present in air fills our alveoli, by the process of diffusion, only oxygen in the air is taken into the blood stream while the other gases along with the waste CO2 is exhaled. So you do breathe in nitrogen, but it is exhaled as it is by the body.

These help the doctor because where there is inflammation there is heat and where ever there is inflammation, that is the part of the body that has the issue so symptoms should arise from that area.
The mRNA processing events that occurs in the nucleus of human cells are as follows:
- 5′-end capping
- splicing
- 3′-end polyadenylation
<h3>What is mRNA processing?</h3>
mRNA is synthesized from a gene as a result of transcription. This mRNA is called pre-mRNA.
However, this pre-mRNA must undergo processing to get rid of unnecessary things before translation into useful products.
The states of mRNA processing are as follows:
- 5′-end capping
- splicing
- 3′-end polyadenylation
These three stages of mRNA processing occurs in the nucleus before the matured mRNA exits for translation.
Therefore, the mRNA processing events that occurs in the nucleus of human cells are as follows:
- 5′-end capping
- splicing
- 3′-end polyadenylation

Answer:
The correct answer is D. amount of collagen present.
Explanation:
As fibroblasts begin to enter the wound site, migrate and proliferate. They lay down the collagen matrix in the wound site. Collagen deposition is important because it increases the strength of the wound. The tensile strength is ergo highest with the most collagen present.
