Answer:
The answer is Option D (The first statement is false and the second statement is true)
Explanation:
Bacteremia also known as “blood poisoning,” which can be categorized as transient, intermittent, or persistent is defined as the presence of viable microorganisms in the bloodstream. It usually occurs when the blood becomes infected with bacteria that are alive and capable of reproducing.
Bacteremia can occur in the absence of wound manipulation or other identifiable risk factors. Some factors such as heart rate, blood volume makes it difficult to quantify bacteria that initially gain entrance to the circulation following dental procedures. Visible bleeding during a dental procedure is not a reliable predictor of bacteremia.
Transient bacteremia is common with manipulation of the teeth and periodontal tissues caused by viridans group streptococci and other oral microflora occurs frequently during daily routine activities such as tooth brushing, chewing food.

A guess based on evidence from the text.
Metamorphic. I looked up some rocks and I’m including the picture of it and it shows something similar to your picture and it says it’s a metamorphic rock.
The answer is <span>Time is the independent variable, and the number of birds is the dependent variable. </span>
<span>An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In Sam investigation, he controls time - he counts birds at 6 a.m. and 6 p.m. So, time is the independent variable. The number of birds is affected during the experiment, so it must be the dependent variable.
