3.8 billion – 2.5 billion years ago
The Archean is the name of the age which started with the shaping Earth. This time of Earth's history endured quite a while, over 2.5 billion years. When the archean age ended the earth was just coming alive.

I believe they will disappear from the area because they’ll either die from the disease in there food or migrate somewhere else for a different source of food
I remember the secondary structure by visualizing it. Understand that primary structure is just the order of the amino acids. The tertiary structure is the 3dimensional configuration of the whole protein molecule with multiple interactions guiding its fold (disulfide bonds, ionic interactions, hydrogen bonds, van der walls). Secondary structure is a step towards the conformation of the protein where it is made up of either alpha-helices or beta-pleated sheets. The alpha helices look like a spiraling staircase while the beta-pleated sheets look like a repetition of long loops. These two structures hold itself by hydrogen bonds.
Based on respiratory function tests, the correct options are:
- spirometer.
- vital capacity
- residual volume.
<h3>What is a respiratory function tests?</h3>
A respiratory function test is a test done to evaluate the ability of the lungs to take in air and remove carbon dioxide
The machine used for this test is called a spirometer.
Therefore;
- Ms. L's respiratory function was evaluate using a machine called a spirometer.
- The amount of air that can be expelled by maximum ex-halation after maximum inhalation is termed the vital capacity
- An increase in the amount of air remaining in her lungs after a normal expiration is called the residual volume.
