30) Which type of light source is primarily utilized in flow cytometry to excite fluorescent markers and analyze cell properties?

	The dye binds specifically to surface markers present only on live cells
	Live cells actively transport the dye into their cytoplasm, resulting in higher fluorescence
	The dye inhibits metabolic activity in live cells, causing them to appear different from dead cells
	Dead cells have damaged cell membranes, allowing the dye to enter and bind intracellular components, while live cells exclude the dye

	The amount of antibody bound to the cell
	The metabolic activity of the cell
	The size of the cell
	The granularity of the cell

	Converts optical pulses into digital values for data processing.
	Transmits data to external storage devices.
	Filters out noise from the optical signals.
	Amplifies electrical signals for better detection.
