To obtain solid NaCl from this mixture, the student should Remove the sand by filtration, then evaporate the water we will get the solid NaCl from the mixture. ( Option 1 )
<u>Explanation:</u>
The mixture contains solid NaCl and sand, in which the sand gets settled down at the bottom of the container, whereas solid sodium chloride (NaCl) gets dissolved in the water.
- We have to first separate the sand by means of a common purification method known as filtration.
- Followed by Filtration of sand we must then filtrate must contain the solution of NaCl, which can be separated by evaporating the solution.
- On evaporation, we will get the crystals of NaCl in the purest form.
Thus we can conclude option 1 as correct answer.
Antiemetics
Antiemetics will most likely be given to chemotherapy patients to treat nausea and vomiting, and up to three antiemetics may be used. The most common serotonin receptor blockers are:
Zofran (ondansetron)
Emend (aprepitant)
Aloxi (palonosetron)
Compazine (prochlorperazine)
Some patients experience nausea and vomiting prior to the infusion. An anti-anxiety medication such as Ativan may be beneficial. A suppository can be used in patients who are already vomiting. Nausea and vomiting can occur before, during, or after chemo treatment. Therefore, to combat the most common adverse effects of chemotherapy, a nurse should administer an antiemetics.
Alternatives to Drugs :
Along with antiemetics, acupressure wristbands, which are available at most pharmacies, may provide some relief.

Answer:
macro-evolution
Explanation:
This happens when evolution occurs because of separation of a population.
Answer:
The light emitted by a light bulb is a form of radiation that occurs when the filament heats up and its thermal emission gains enough energy to move into the visible spectrum.
Explanation:
Light bulbs contain a filament which is heated up electrically. When this filament is heated up,energy in the form of heat is imparted to the electrons in the filament.
This thermal excitation of electrons ultimately leads to emission of light in the viable spectrum. This light is now radiated through a light bulb.
