If CPR is not performed, C. 4 minutes will elapse before the brain becomes damaged from lack of oxygen.
One minute isn't enough time - you can even hold your breath for one minute without fainting. Some people can even do it for 2 minutes.
Ten minutes is too long - you would be long dead.
Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.
<h3>What we know about evolution. </h3>
- This is a theory that was put forward by Charles Darwin.
- Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
- The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
- These changes are hereditary.
Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.

There are so many examples for that in different areas, like biology experiment carried out in our lab recently.

Answer:
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
Explanation:
<span>No change in temperatures between seasons. Tilt is the angle between the direction of positive pole and the normal to the orbital plane. Seasons occur due to the tilt of axis. If there is no or zero degree tilt there will be no season. Season means changes in temperature. the amount of sunlight received remains same throughout the year which causes for no change in temperature and hence no season.</span>
