Answer:

A control should have been included in the investigation  

Explanation:

It is impossible for the student to interpret a correct conclusion about his experiment, without adding a control treatment where he can really compare the differences between the variables.

Control treatment is an element of research that receives all factors, except the variable being tested. The control serves to make comparisons with the other treatments, allowing to observe the exact difference between a system where the variable was tested and the system where it was not.

In the case of the question above, it would have been necessary for the student to have placed a cart on a ramp of normal height and without sandpaper. That way he could compare the speed between this cart and the carts on the other ramps, thus having a correct result.

Your roommate says that you seem to wake up dozens of times in the night, gasping for air, but are totally unaware of it. Based on this information, you may be experiencing sleep apnea.

<h3>What is Sleep apnea ?</h3>

Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. If you snore loudly and feel tired even after a full night's sleep, If it goes untreated, it can cause loud snoring, daytime tiredness, or more serious problems like heart trouble or high blood pressure.

The main types of sleep apnea are:

  • Obstructive sleep apnea, the more common form that occurs when throat muscles relax.
  • Central sleep apnea, which occurs when your brain doesn't send proper signals to the muscles that control breathing.
  • Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, which occurs when someone has both obstructive sleep apnea and central sleep apnea.

Which TWO factors contributed to the Nazis rise to power in Germany before World War II?
devlian [24]

Answer:

<u><em>Answer choice B and C.</em></u>

Explanation:

The primary reason for the Nazi party's rise to power was economic desperation. Before the Great Depression hit Germany and put millions out of work, the National Socialist party of Germany was a fringe party on the far political right. Many people equated the depression to Germany's defeat in World War I, and general consensus, particularly among the working class, was that the Parliament was impotent to solve any economic crisis.
