<span>The body is constantly changing, no matter what age. It has to maintain homeostasis, or balance at all times or illness/death occurs. If your body is weakened, it then becomes harder to maintain this state. If one component goes out of balance; ie, water content, it affects the whole body. Swelling(edema) CHF(serious heart problem) kidneys may be overtaxed/unable to release the extra fluid. As the body ages organs naturally become less efficient, therefore making homeostasis more challenging.</span>
Answer:
it was a SEA STACK.
Explanation:
A sea stack is formed from cliffs. It is a part of the cliff that breaks off from the original structure because its connecting portion will erode and be gone due to weathering and constant barrage of waves on the cliff sides.
what you mean in this question?
The options for this question are:
A. Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B. All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
C. Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
The best answer choices are:
A & C
Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
Explanation:
Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Sensory receptors located in the dermis or epidermises of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors.
