What else can I help you with?
A marker molecule on a cell that the immune system uses to recognize a pathogen?
The major histocompatibility complex (MHC) molecules are marker molecules on cells that the immune system uses to recognize pathogens. MHC molecules present fragments of pathogens on the cell surface to alert immune cells to the presence of the pathogen. This helps the immune system to target and eliminate infected cells.
What recognize a hormone's chemical structure?
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
What structure in a plant cell helps it from osmosis?
cell wall
What are the structure of the cytoskeleton in a cell?
it helps keep the cell in shape.
Single cell pathogen with no nucleus?
The single cell pathogen with no nucleus is a prokaryotic organism. Prokaryotes, such as bacteria, lack a membrane-bound nucleus and their genetic material is found free-floating in the cytoplasm. This simple cell structure allows them to replicate quickly and adapt to various environments.
What is the function of lipoteichoic acid in gram positive bacteria?
Lipoteichoic acid in gram positive bacteria plays a role in cell wall structure and stability. It helps regulate the movement of ions in and out of the cell, and also serves as a ligand for host cell receptors, which can influence the host-pathogen interaction.
How does the structure of the fat cell help with its function?
A fat cell is a round cell. The structure of the fat cell that helps the cell function is the shape allows the fat cell to accumulate a lot of lipids.
What recognizes a hormone's chemical structure in the endocrine system?
Hormone receptors on cell membranes recognize a hormone's chemical structure in the endocrine system. When the hormone binds to the receptor, a cell changes its behavior.
What cell structure helps maintain homeostasis by controlling the movement of materials into the cell?
The nucleues, the brain of the cell.
What are the structure and the function of the cytoskeleton?
it helps keep the cell in shape.
Is a whiplike structure that helps a bacteria cell move?
Flagellum.
