The variables in the above experiment are as follows:

  • Independent variable: length of light
  • Dependent variable: height of plant
  • Experimental group: The plants kept under bright sun lamps all night long
  • Control group: Plants not kept under bright sun lamps all night long

<h3>What is an experiment?</h3>

An experiment is a test under controlled conditions made to either demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.

In an experiment, variables are involved and they include;

  • Independent variable; which is the variable that is changed or altered in the experiment
  • Dependent variable; which is the variable that is measured or recorded in the experiment
  • Control group; the group that does not receive experimental treatment
  • Experimental group; the group that receives experimental treatment

According to this question, a student wants to study the effect of sunlight on plant growth. In his experiment, 12 plants receive normal amounts of sunlight, but half of them are kept under bright sun lamps all night long.

This suggests that the following applies;

  • Independent variable: length of light
  • Dependent variable: height of plant
  • Experimental group: The plants kept under bright sun lamps all night long
  • Control group: Plants not kept under bright sun lamps all night long

MrRa [10]

You must immediately report any symptoms like chills, nausea, or itching

<h3>What should a nurse do during blood transfusion?</h3>

The nurse must take baseline vital signs just prior to the infusion of blood or a blood product and then the nurse should remain with and monitor the client for at least 15 minutes after the transfusion begins at a slow rate since most serious blood reactions and complications occur shortly after the transfusion begins

With this information, we can conclude that Although the nurse can identify objective signs of a transfusion reaction (changes in vital signs, flushing, cyanosis, coughing, and to some extent, dyspnea), the nurse might not be able to tell if the client is experiencing subjective symptoms
