200 ml of 4% solution contains 400 mg of medication
Explanation:
- 0.5 ml of solution has 1 mg of medication
- for example, if 10 mg of medication needs to be determined all we must do is multiply 0.5 ml of solution by 10 mg of medicine to get the answer.
- in the above question we need to determine the number of milliliters of a 4% solution containing 400 mg of medication.
- all we must do is multiply 0.5 ml of solution to 400 mg of medication to get the answer.
0.5 ml x 400 mg = 200 ml
It is D the to help with spelling the others don’t make any sense and so it’s d yeahhhggg
Answer:
Pulmonary circulation
Explanation:
is the movement of blood from the heart to the lungs for oxygenation, then back to the heart again. Oxygen-depleted blood from the body leaves the systemic circulation when it enters the right atrium through the superior and inferior venae cavae.
Answer:
If red blood cells are placed in a hypertonic solution, they will shrink because the water moves out of the cell through osmosis. When red blood cells are places in hypotonic solution they swell and rupture because the water moved in the cell through osmosis.
Explanation:
If red blood cells are placed in 1400mOsm of NaCl, the cell volume will be lost because the wayer in the cell moves out due to higher concentration of salt outside, they will shrink.
Similarly if the red blood cells are places in urea and NaCl the cell will again shrink.
Answer:
The correct answer is D. resting phase
Explanation:
Diastole is the resting phase when relaxation of heart muscles takes after contraction(systole). In this phase blood from veins and coronary sinus comes into the auricles and ventricles because of the pressure in the heart is less than veins and opening of A-V valve.
When both auricles and ventricles are relaxed it is called joint diastole. Joint diastole is called complete cardiac diastole and is 0.4 sec long. After the joint diastole auricular systole occurs in which auricles are contracted and ventricles are still relaxed called ventricular diastole.
After the end of auricular systole ventricles contraction starts and auricular relaxation occurs called auricular diastole.
