diamong [38]

To test his hypothesis, the student will have to design an experiment to measure the effects of <u>temperature on cellular growth</u>.

To test the effects of temperature on cellular growth the student will have to create an experiment containing the there kinds of variables:

  • Dependent
  • Independent
  • Control

In this experiment, the control variable will be the kind of cells used, as well as the incubation methods being used. We identify these as the control variable given that they will remain constant.

The independent variable will be the Temperature at which we will place each cell being studied. The dependent variable, on the other hand, is by definition, what we seek to measure. In the case given it would correspond to the amount of cellular growth.

To test his theory of the effects of temperature on cellular growth, a student can design an experiment in which the control variable will be the cells themselves, the independent variable will be the Temperature, and the cellular growth can act as the dependent variable.

Which of the following are appropriate units for power?
Vlad [161]

Question: Which of the following are appropriate units for power?

A) newton·meter

B) watt

C) H.P./sec

D) joule/sec

Answer:

Watt  and Joule/sec are the appropriate units for power.

Explanation:

As per the question, the physical quantity given is power.

The power is defined as the rate of consumption of energy or the rate of doing work.

Let us consider W is the amount of work done by a body in time t .

Mathematically the power of that body is written as -

                                power p = \frac{W}{t}

The unit of work is joule and the unit of time is second.

Hence, the unit of power is joule/sec.

we know that one joule/sec. = one watt.

Hence, watt is also another unit of power. Newton-metre can not be a unit of power . It may be considered as a unit of work.

Similarly H.P/sec is also not a unit of power. Here H.P stands for horse power which is another unit of power . Hence, joule/sec. and watt are the appropriate units of power.

Your heart has four valves. Normally, these valves open to let blood flow through your heart, and then shut to keep it from flow
Ulleksa [173]

Regurgitation influences the flow of blood by mixing the oxygen-poor blood with the oxygen-rich blood. Due to this, the heart has to pump more to oxygenate the entire body, leading to the rapid, and fluttering heartbeat. The tissues get oxygenated but regurgitation could be fatal, as the heart cannot function overtime forever.  

Valve prolapse influences the flow of blood when the flow of blood backs up. This leads to an irregular or racing heartbeat. Even at certain occasions, the blood can flow back to the lungs. However, there is not a huge influence in the oxygenation of the body tissues.  

Stenosis makes the ventricles to pump overtime to get enough blood through, and in the process, the ventricles thicken. This functions for a while, however, it will result in heart failure as the heart cannot do it for entire life. The tissues are oxygenated, but it will be an issue due to overtime.
