A 42 year old man will have less calcium
Well, a compound forms whenever two or more atoms form chemical bonds with each other. Each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms.
Knowing specifically and accurately that water is for sure a compound makes it special and very interesting.
To start, move the objective lens to its lowest power setting. Place a slide on the stage with the label side up and the cover slip in the middle. You can only use the coarse focus knob when the power is low. If you can't see anything, move the slide a little while you look and focus. If nothing shows up, turn down the light and move the slide a little while you're looking and focusing. Once you're in focus on low power, move the slide to make the object of interest in the middle of it. Turn the objective to medium power and only change the fine focus. If you need to, turn the objective to high power and only adjust the fine focus.
Answer:
prolongs the anesthetic effect of the drug
Explanation:
The epinephrine acts as a vasoconstrictor agent to some local anesthetic drugs. The systemic absorption slows down with the addition of 5 micrograms per mL of epinephrine. The epinephrine enhances the anesthetic effect of the drugs. It act as a adjuvant in local anesthetic drugs. The adjuvant increases the effect of immune response. The epinephrine also act as drug for anaphylactic reaction during emergency. The dopamine receptors are present in CNS. The epinephrine is not involved in lowering blood pressure and low heart beat. The epinephrine stimulates secretion of prostaglandins.
Thus, option B is correct. So, the addition of epinephrine to some local anesthetic drugs <u>prolongs the anesthetic effect of the drug.</u>
Answer:
The correct answer is option 4.
Explanation:
Viruses cannot be considered alive as they cannot carry out metabolic reactions on their own. Metabolism signifies the tendency to gather and use energy. The chemical reactions in the cells spontaneously change the molecules into the forms of energy, which can be utilized by the organism.
However, in the case of viruses, they are too small and simple to collect and utilize their own energy. They are completely dependent upon the host cells for energy. The viruses only require energy when they need to make duplicates of themselves, however, they do not require any energy when they are present outside of the cell. Thus, as they cannot carry out metabolic reactions, they are not considered as living.
