60 seconds
To ensure that all bacteria are removed from the puncture site for blood cultures, the site should be cleansed using friction for a minimum of 60 seconds.
<h3>Where exactly is the puncture site?</h3>
- The proper location must be cleansed and punctured with a lancet so that a drop of blood can be softly expressed before blood can be collected using a capillary tube.
<h3>But what constitutes a
suitable location? </h3>
- Finger: In both adults and children, the third or fourth finger is typically favored location as a puncture site
<h3>Where on the body does a skin puncture most frequently occur?</h3>
- The most frequently used site is the distal end of the third or fourth finger.
- Because the bone is so close to the skin surface, there is a higher risk of puncturing the bone at the very tip of the finger.

The statement 'Exploring the relationship between the material in a rock sample and its hardness' correctly describes an experimental investigation (Option C).
<h3>What is an experimental investigation?</h3>
An experimental investigation is defined as a procedure used in the scientific method to test an explanation or hypothesis, which can be confirmed or rejected.
In conclusion, the statement 'Exploring the relationship between the material in a rock sample and its hardness' correctly describes an experimental investigation (Option C).

A quadratic equation has the general form of:
<span>
y=ax² + bx + c
</span><span>
It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:
</span><span>
y = a(x+h)² - k
</span><span>
where h, k are the vertex points.
</span><span>
y=-2x^2 + 2x+ 2
</span><span>y=-2(x^2 - x) + 2
</span><span>y + 1/4 = -2 (x^2 -x +1/4) + 2
</span><span>y = -2 (x - 1/2)^2 + 7/4
</span><span>
Therefore, the vertex is (-1/2, -7/4)

at x = 6, y = -58</span>
Endospore staining is used to stain the spore which reside inside the microorganisms, and unlike the exospores, are not present outside the microbial cells. The endospore stain penetrates the microbial cells, and then stain the endospore.
