Answer:
The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life".
Explanation:
The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.
The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.
Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.

Answer:
Explanation:
Scientific Research is a method used in the construction and testing of a scientific hypothesis.
It has six steps that can be used in solving questions ask or observations made which is A family wants to test the effectiveness of a misting shower head in conserving (saving) water compared to their regular shower head.
Steps to follow:
Make an observation: An observation would be made on how water is been used in the house and how it can be conserved, this observation is what brings about the question asked
Ask a question : The question is
which is more effective in conserving water a misting shower head or regular shower.
Form a hypothesis, or testable explanation: An hypothesis is formulated for the question asked
Example: Null hypothesis: Mistling shower conserves more water than shower head
Alternative: Mistling shower conserves less water that normal shower.
Make a prediction based on the hypothesis: Predictions are made on what could be the cause if there is indeed a difference and what could cause the difference
Test the prediction: An experiment is conducted to test the hypothesis if indeed Mistling is better than normal shower, the appropriate method is determined to be used for the experiment.
Iterate: The result gotten helps to butters our hypothesis if its to be acceoted or rejected. If rejected further research can be conducted on the effectiveness of normal shower in conserving water.
