Have you ever experienced swollen lymph nodes when you were sick? Why might this happen?
ivann1987 [24]

Answer:

Yes, swollen lymph nodes are more common than some might think.

Explanation:

The medical terms for swollen lymph nodes are adenopathy or lymphadenopathy.

Lymph nodes play a vital role in fighting off sickness in the body. They act as a filter, trapping bacteria and viruses before they can spread too far.

Lymph nodes <em>typically</em> swell up as a response to bacteria or viruses. Though cancer can be a factor in swelling, it is very rare. Most commonly they are felt right below the corner of the jaw, in the neck. Yet, they are not only in the neck; they are all throughout the body. When they are swollen, they might feel tender or even painful.

When did Cyanobacteria start producing pure oxygen
Travka [436]

<u>Answer:</u>

Cyanobacteria start producing pure oxygen around 200 million years ago.

<u>Explanation:</u>

Many scientists believed that Earth did not have any oxygen. Cyanobacteria or the blue green algae are the microbes which produced oxygen for the first time with the help of photosynthesis.  This was around 4.5 billion years ago: after Hadean eon.

They were very simple, but they produced oxygen in the early earth’s atmosphere. So, they brought evolution on earth. This “blue-green algae” exists in salt water, rocks and soils and play a major role in maintaining the ecosystem.
