Common parts of a cell
The cell is the building block of an organism, its smallest living unit. By definition, all cells have the following:
<span>A cell membrane: As a barrier between the cell and its environment, the membrane provides structure, protection and control over the movement of materials in and out of the cell.Cytoplasm: This refers to the contents of the cell membrane excepting the nucleus. One of its main components is cytosol, a jelly-like substance which acts as protection and support for the remaining contents.<span>DNA: Each cell contains genetic material. However, the way it is stored is one of the distinguishing factors between a eukaryote (a plant or animal cell for example) and a prokaryote (like a bacterium). These represent the two main types of cells. The former has a nucleus — for its DNA — as well as other organelles while the latter does not. Organelles are parts of a cell that have a specialised function and their own membranes.</span></span><span>Nucleus</span>
<span>There would be
a delay between the ECG pattern and the resulting beat of the heart because it
takes time for the pulse to travel from the systole (ventricular contraction)
to the radial artery. Pulse cannot be felt in the finger. It can be felt with a
pulse oxymeter.</span>
I believe it’s the y variable.
