Prions are misfolded versions of normal proteins that can cause diseases. So the correct option is D.
<h3>What leads to prion disease? </h3>
A misfolded confirmation of proteins is called Prions. These misfolded proteins can result in harmful functional proteins and cause several diseases.
A prion is the type of protein that usually cause the normal proteins in the brain to fold in an abnormal manner. This results in misfolding of proteins in the brain.
Prion diseases are known to affect both humans and animals. Sometimes, humans get prion diseases by consumption of by meat from infected animals.
Creutzfeldt-Jakob disease is the most common prion disease in humans. The occurrence of prion diseases is rare. In the US, about 300 cases are reported every year.
Therefore the correct option is D.

Pretty much any research requires good observational skills. You have to be able to observe and record what is happening. Obviously the more you can see, the more you can record.

<span>C) growing, processing nutrients, reproducing
Let's look at the 4 options and see which makes sense.
A) working, growing, eating food
* Not so sure about all organisms being able to work. Also the eating food part seems questionable to be, depending upon how you define eating. After all, plants don't eat like you may consider eating. There's likely to be a better choice later. So consider this wrong for now.
B) photosynthesis, reproducing, growing
* There's an immediate problem with this choice. Plants do perform photosynthesis and are considered alive. But animals don't. So photosynthesis isn't something all organisms can do. So this is a wrong choice.
C) growing, processing nutrients, reproducing
* Can't see anything wrong here. An organism needs to grow. It has to process nutrients in order to grow. And if it doesn't reproduce, it will eventually die and leave nothing behind. So this is the correct choice.
D) running, breathing, watching TV
* This choice is wrong on so many levels. Trees which are an organism can't run, nor watch TV. So this is also wrong.</span>
