“Advantages of Digital Communication. The effect of distortion, noise, and interference is much less in digital signals as they are less affected. Digital circuits are easy to design and cheaper than analog circuits. The hardware implementation in digital circuits, is more flexible than analog.” In general, digital is far easier to handle and has (virtually) unlimited precision (limited only by hardware constraints and compute time).
Analog computation takes place at a significant portion of the speed of light (the time it takes for an electrical signal to traverse a circuit). However, it is almost impossible to correct completely for noise, and precision is limited to three (or at most four significant digits).
Laws can be tested over and over and their results will still be the same, and laws cannot be disproved. Theories can always be disproved beause they are tested and experimented continously and results can change. Laws can't be theories but theories can be turned to laws. Hope this helps, didn't know an exact answer to that but I hope you can draw your answer from this information.
Answer:
on channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
The ability of cells to communicate through chemical signals originated in single cells and was essential for the evolution of multicellular organisms. In multicellular organisms, cells send and receive chemical messages constantly to coordinate the actions of distant organs, tissues, and cells. Cells can receive a message, transfer the information across the plasma membrane, and then produce changes within the cell in response to the message. Single-celled organisms, like yeast and bacteria, communicate with each other to aid in mating and coordination. Cellular communication has developed as a means to communicate with the environment, produce biological changes, and, if necessary, ensure survival.
Answer:
A. Skeletal muscles
Explanation:
An effector is a group of cells, an organ, gland or any part of the body that acts to bring about a change in response to a nerve impulse from the CNS.
In the case of thermogenesis as stated in the question above, where a drop in temperature is detected by thermoreceptors in the CNS, the part of the body that responds in returning the body temperature back to its baseline are the skeletal muscles. The skeletal muscles are the effectors that responded in repeated contracions to generate heat.
