When it comes to blood circulation, a good and effective blood circulation is one that provides the body with a lot of nutrients - so what we want is for example an increased blood circulation to the body, but we don't want for example a decreased blood flow to some organs - those organs would then not receive the necessary nutrition. Healthy lifestyle provides good things to the body - so the answer is D, since it's the only good thing. Decreased area in blood vessels would again diminish the nutrition to some organs and a high blood pressure is also not good - it carries a risk of some diseases.

Answer:
Alcohol, for example, produced a release of dopamine from about 100 units to about 200, You get a similar magnitude of an effect with nicotine. Cocaine produces a huge release of dopamine, from 100 units to about 350 units, however the mother of them all is methamphetamine.
so it really depends on the drug.
please mark me brainliest!
It would be D cause of the semi cold temperature would not freeze but thicken the liquid.
Answer:
Similarly, your muscles and other parts of your body need to have a continuous supply of glucose (or other high-energy molecules) and oxygen to provide the energy for muscle contraction and other body functions. When your body breaks down glucose, carbon dioxide is produced.
The odorant molecules arrive either directly by diffusion into the mucus, or are supported by transport proteins (odor binding protein or OBP) that allow the hydrophobic molecules - majority - to penetrate the mucus covering the epithelium, and thus to reach the membrane receptors present on the eyelashes of the olfactory neurons. These transport proteins are thought to concentrate odorant molecules on membrane receptors. As ligands, the odorant molecules bind to membrane receptors on the eyelashes, triggering a transduction pathway for a stimulus involving G.olf protein (first messenger), adenylate cyclase, and cAMP ( second messenger). The second messenger causes the opening of ion channels Ca2 + / Na + present on the plasma membrane of the olfactory receptor, these two ions then enter the cell. Ca2 + causes the opening of a Cl- channel, the output of this ion causes depolarization of the membrane so that the olfactory receptor produces action potentials. These impulses will go directly to the olfactory bulb, in the prefrontal region of the brain, where this information (and that of taste) is processed by the body.
