450 mya, is where you would find fossils.
Explanation:
The first layer would be newer organismis that haven't quite decayed yet.The second and third layer is where the bones of the dead organasims lie, they havent quite been through the whole process yet, but they are nearly complete just about 100,000 years left.The fourth layers have been through alot, and have been there for many many years we can say abot 100,000,000 years.They are ready to become a fossil fuel.
The greater the attractive forces between substrate and enzyme, that
enzyme is said to have a higher affinity for the substrate.
<h3>What is an Enzyme?</h3>
This is a substance which acts as a catalyst in regulating the biochemical
processes of the body.
Enzymes are substrate-specific which means they act only on some types
of compounds. For example the enzyme protease acts only on protein.
When the attractive forces between substrate and enzyme is great then
the enzyme is said to have a higher affinity for the substrate.

<h2>
Answer:</h2>
The difference is that Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy to cells.
Answer:
B. The conditions in their muscles have become anaerobic.
Explanation:
In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.
What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.
Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".
