quantity of the substance remaining = initial quantity of the substance * (.5)^(time elapsed/half life of the substance)
2.50 = 20 * (.5)^(19.2/x)
Answer:
D)clues about the past climate of Earth
Explanation:
The fossil record certainly has gaps, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. Thus, many pieces of the puzzle are missing; some will never be found.
So you have a muscle like the biceps brachii it’s origin is connected to the humerus then inserts to the radius origin didn’t move it’s static
When the rates of the forward and reverse reactions are equal. The system is dynamic because individual molecules react continuously. It is at equilibrium because no net change occurs.
Here are the steps;
step 1. The activated myosin head binds to actin, forming a cross bridge.
Step 2. ADP is released and myosin slides the thin filament toward the center of the sarcomere.
step 3. ATP binds to the myosin head and detaches it from actin
step 4. ATP is hydrolyzed to ADP and P(i) and the energy released re-elevates the myosin head.
