Gram-positive does not refer to a positive charge, but to the purple color of the stain. Gram-negative bacteria do not retain the purple dye and are instead red in color.
Yes, water is not an electrolyte. Electrolytes are minerals that carry an electric charge and are found in fluids inside and outside of cells in the body. Water, on the other hand, is a neutral substance that does not carry an electric charge on its own.
blood cells do not carry food, blood cells carry oxygen.
Yes, the sodium-potassium ATPase pump helps maintain the resting membrane potential of cells by transporting three sodium ions out of the cell and two potassium ions into the cell for every ATP hydrolyzed. This generates a net positive charge outside the cell and a negative charge inside the cell, contributing to the overall negative resting membrane potential of the cell.
Red blood cells carry oxygen to all the cells of the body.
Nerve cells
They carry negative charge and are repelled by negatively charged cell structures. Basic dyes are opposite (carry positive charge) and are attracted to negatively charged cell structures.

Solar panels generate electricity through photons from the sun knocking electrons loose from atoms in the panel material. This creates a flow of electrons, which creates a positive charge on one side of the panel and a negative charge on the other.
Negative staining techniques are designed to stain everything BUT the bacterial cells. This allows us to see the cells unstained and helps us observe their morphology (how the cells are shaped and how they group together). The cells have an overall negative charge on their surface, so they naturally attract positive charges. Crystal Violet carries a positive charge, so it would adhere to the surfaces of the cells thus staining the cells (which is not what you want in a negative stain!)
there are different types of cells that carry messages
Red blood cells carry oxygen around the body and to the cells.
The type of cells that carry mutated DNA is the boold cells
The Gram positive bacterial cell wall is made up of thick peptidoglycan layer which is rich in Teichoic acids. These teichoic acids are negatively charged because of presence of phosphate in their structure. The Gram negative bacteria have an outer membrane composed of phospholipids and Lipopolysaccharides. The lipopolysaccharides impart a strongly negative charge to surface of Gram negative bacterial cells.
Humans do not possess a net charge; rather, our bodies are electrically neutral overall. The positive and negative charges within our bodies are balanced, with elements like sodium and potassium ions contributing to electrical activity in our cells but not resulting in an overall charge imbalance.
Erythrocytes carry hemoglobin. These cells are also known as red blood cells.
Erythrocytes are the cells that carry hemoglobin. Their common name is red blood cells.
