There are no options to choose from and this makes it hard to answer the question. I hope my answer is correct and comes to your help. The reason that the new recruit fainted was that he did not use muscular compression to return the blood to the heart and thus his brain became devoid of oxygenated blood, resulting in the new recruit getting fainted.
Answer:
light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.
Explanation:
lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
The result which would be seen from a properly prepared negative control is nothing.
<h3>What is a Negative control?</h3>
This type of control is used to test and ensure that in the absence of the antigen we do not still get a positive reaction.
Since proper aseptic technique was practised and there was no swabbing of the surface then there would be nothing seen in the properly prepared negative control.

Answer:
Most people who get the flu (either seasonal or 2009 H1N1) will have mild illness, will not need medical care or antiviral drugs, and will recover in less than two weeks.
