you didnt include the following so im going to give it my best shot. Ray should use his knees to lift instead of his back. if it ecsalates to an injury he should follow the RICE procedure.. Rest. Ice. Compression. Elevate.
Explanation:
Answer:
contraction of the arrector pili muscle fibers.
Explanation:
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.
Cells respond to environmental effects through signal transduction, which promotes healthy cell growth and normal cell function.
<h3>Why is the signal transduction step necessary?</h3>
The reason why after a signal binds to a signal receptor, we need the next step is as follows:
- For the purpose of triggering an appropriate cellular response, living creatures have evolved a vast range of intricate procedures to send signals from the outside to the inside.
- These molecular pathways can develop flaws that result in a variety of ailments, including diabetes, cancer, and psychotic conditions.
- It is the mechanism by which a cell responds to the stimuli it receives from the environment by diffusion of those signals to its internal compartments.
- Signal transduction is the process by which a cell translates a given signal or external stimulus into another signal or specific response.
- First, a particular receptor on the cell's membrane or cytoplasm must be activated by a signaling molecule (also known as a ligand). transduction.
- Ligand-receptor binding is extremely specific; it can be compared to a lock and key.
- Second messengers are chemicals that enable intracellular signal amplification after a signal has been received.
- A ligand's interaction to a receptor may result in the production of hundreds of second messenger molecules, which may then change thousands of effector molecules to cause a variety of reactions.
- Signal transduction enables cells to perceive, interpret, and react to various environmental signals, enabling them to carry out their usual functions.
