the answer is b. energy and matter can enter and leave.
Methods of DNA typing for identity, parentage, and family relationships. RESTRICTION FRAGMENT LENGTH POLYMORPHISM (RFLP) ANALYSIS.
Explanation:
Most of the cell surface receptors and glycoproteins. These glycoproteins have active sites that recognize specific signals, like hormones, that initiate secondary signaling pathways inside of the cell, in response to the external signal. This is how cells respond to environmental stimuli.
If a change in glycoproteins makes them unable to bind signaling molecules (like hormones) or makes them permanently bind these molecules, there will definitely be a defect in how the cell responds to external stimuli. The cell will be, for example, be unable to respond to insulin in case of elevated blood sugar levels as is the case with diabetics.

The water cycle is a system that shows how the water moves around in different states to transport itself. It uses different states which show a different transportation such as evaporation or condensation. The water cycle can also use continuous movement above and below the earths surface. There are five main steps to the water cycle which are evaporation, condensation, precipitation, transpiration, and runoff but there are still many more.
Hope this helps! :)
Answer:
For this receptor, the stimulus begins with an explosion of action potentials.
that would be the correct option.
Explanation:
A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.
Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.
It keeps the nervous system constantly active in the environment that surrounds it.
They are slowly adaptable, an example of these receptors are the merkel and ruffini receptors.
