An electrocardiogram (ECG) provides information about B) the rhythm of heart contractions
The rhythm of heart contractions can be known by an electrocardiogram (ECG).
An ECG or Electrocardiogram is a method to diagnose the heart conditions to check the normal functioning of the heart.
The process to measure the electrical signals of the heart can be done by using this machine.
In this technique, three leads are attached to both the wrist and the left ankle to measure the electrical activity of Heart. The rhythm of the heart contraction and relaxation can be used to find out any heart abnormality.
It is used to investigate the heart problems associated due to bad health or some chronic inflammation affecting the functioning the body. Shortness of breath or nausea is investigated by using an ECG machine to help the patient and doctor to find out the cause.
It consists of QRS complex which measures the heart beat.

Answer:
Explanation:
Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.
Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.
6CO2 + 6H20 --------> C6H12O6 + 6O2
Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.
C6H12O6 + 6O2 ------> 6C02 + 6H2O
One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.
A hypothesis is an idea or explanation that you then test through study and experimentation. A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. . Most hypotheses can be supported or refuted by experimentation or continued observation. Theory: A theory is more like a scientific law than a hypothesis. I hope this helps!
