certain hydrogen bonds are formed so that A goes with T and G with C
Answer:
negative feedback
Explanation:
Insulin reduces blood sugars when the levels are high in the blood. The hormone is produced by the pancreas and binds on receptors of cells. This initiates cell signaling mechanisms that signal the cell absorb sugars. When the blood sugars get back to normal, insulin production is reduced.
Answer:
vasoconstriction of capillaries.
baroreceptors in the aortic arch.
Explanation:
Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.
Actually the answer is none of the answers
They are all transfer of heat in many ways
In order for you to enjoy the smell of a flower, molecules called <u>Odorants </u>from the flower must land on your olfactory epithelium, which lines the inside of the nose.
- When a person breathes in air containing odor molecules, the molecules attach to receptors in the nose and send signals to the brain.
- Odorants interact with primary epithelium olfactory receptors. Olfactory receptors, a type of epithelial cell with cilia, are found in the olfactory epithelium. These receptors receive the sense of smell, which is then sent to the brain.
- The sensory neuron connected to the receptor is activated when an odorant connects with a receptor that detects it.
- Only olfactory stimulus directly communicates with the cerebral cortex; all other sensory information is sent through the thalamus.
- Additionally, it has been suggested that the nasal mucus plays a role in the process of emulsifying hydrophobic odorant molecules, delivering them to receptor sites.
