Answer:
A
Explanation:
The other answer choices are false and the three parts of the cell theory is
All cells come from other cells, all living things are made of one or more cells, and the cell is the fundamental structure of life.
Answer:
Sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
Mechanical Input enters the body using vibrations through the skin and ears.
Chemical input enters the body using molecules through the nose and mouth.
Electromagnetic input enters the body using waves through the eyes.
In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.
