Vitek1552 [10]

Answer:

When your graphing to data from an experiment.

Explanation:

You use any type of graph when you're doing an experiment because, in the beginning, you start by marking where you started then as time goes on you mark it accordingly. For example, say your starting at 5cm on a plant so on the line/bar graph you make 0 you 5 since that is where you're starting at.  when you water the plant you decide to give it 10cm of water and put it in the sun constantly. A week later of sun and water it grew 10cm, so you mark it on your line/bar graph to show how much it grew over time. Make a little bit more sense?

<h3>What are the risks of infection from blood?</h3>

The likelihood of contracting an infection increases if you break or pierce your skin while coming into contact with contaminated blood. For instance, if you pierce your skin with a sharp tool that has contaminated blood on it, like a used needle.

If blood only comes into touch with your eyes, mouth, nose, or already broken skin, the danger of contracting an infection from it is reduced. For instance, if someone spits in your face, their saliva may contain blood and could end up in your mouth, nose, or eyes.

Additionally, infectious saliva may enter an already open wound, graze, or scratch. If infected, there is relatively little danger of infection. If infected blood comes into contact with intact skin, the chance of infection is quite low.
