Your answer is C.
Not all systems perform the same function or use the same organs.
<span>If there is not enough carbohydrate available in cells to allow the acetyl-CoA to enter the citric acid cycle, it will be used to make ketones. Acetyl-CoA is a molecule that is important in some biochemical reactions involving protein lipid and carbohydrate metabolism. It function to transport an acetyl group to the citric acid cycle or the Krebs cycle for it to be oxidized for the production of energy. Ketone can be produced and is regulated from the acetyl-CoA. The rate of the production of this substance would increase during starvation or in other words there is less carbohydrates that is available in the body.</span>
Answer:
No, it has too many variables or possible changes.
Explanation:
If you carried out an experiment or research on something, you have to given the same environmental and soil conditions to the factors. In this experiment, Kevin put the first plant in large pot and the other two plants in the field conditions. For performing correct experiments, Kevin put all the plants in separate pots or in the field conditions.
When i observe internal parts of plants , i feel that its structure and functions are very complex and dependent from one another
If one part of the plants fail to do its function, it will be most likely that other parts of the plants will be disturbed too
hope this helps
Answer:
P wave
Explanation:
Electrocardiogram records the strength and timing of electrical activity in heart. As various regions of heart contract at different times and for different duration, the electrical activity is not constant and shows a series of rise and fall. There are three main components of ECG: P wave, QRS complex and T wave.
P wave indicates the beginning of electrical signal in the right atrium. The signal spreads in both right and left atria which leads to their contraction. As a result, blood is pumped into the ventricles and rest of the process occurs.
