The information from a signal molecule present outside the cell elicits intercellular response when the G protein coupled receptors interact with the wide variety of molecules on the outer surface of the cells.
G Proteins are the specialized proteins having the ability to bind GTP and GDP and is of three units called Alpha, Beta and Gamma subunits which together formed G proteins.
When G protein is activated it will bind GTP and each receptor binds in lock and key method and binding result into conformational change which will trigger a complex chain of events influencing different cell function.
Features exhibited by Signal Transduction System are:
1. Specificity- Signal molecules fits binding site on its complementary receptor. Other signal do not fit
2. Amplification- When enzymes activates enzymes, the number of affected molecules increases.
3. Desensitization- Receptor activation triggers a feedback circuit that shuts off the receptor or removes it from the cell surface.
4. Integration - When two signals have opposite effects on a metabolic characteristics outcome results from the integrated input from both the receptor.

Answer:
You will need to prepare just incase it happens. Meaning buy grocceries, shelter and comfort items. And make sure to stay indoors at all times and stay away from windows or anything dangerous.
Hope this helps :)
If so brainliest would mean alot thanks!
Answer:
C. ACFEI
Explanation:
ACFEI certification is given to professionals with the ability to examine and interpret situations related to forensic technology. Thus, professionals with this type of certification are able to act in the examination of bodies and other factors related to injuries from violent causes that may or may not have led to a fatality.
For this reason, we can conclude that Ned has this type of certification.
Answer:
variations
Explanation:
if there are variations of something, then there will be different occurrences in the same species. Hope that this helps you and have a great day :)
The answer would be C, welcome
