Answer:
The correct answer is A.) Sister chromatids are pulled apart.
Explanation:
This is because during Anaphase II in Meiosis, the sister chromatids are pulled apart.
Chromosome pairs line up during Prophase I. <em>Not B.</em> When the chromosome pairs pair up this is also Metaphase I. <em>Not C.</em> When chromosome pairs are pulled apart, Anaphase I is occurring.

Answer:
X is the concentration of the substance being measured and Y is the response from the instrument that is being used to measure
Explanation:
A calibration curve is the plot of known concentration of substances where x is the increasing known concentration and Y is the response, typically "absorption" taken from the instrument that is used for measuring. This curve is then used to find out the concentration of the unknown substance by using it's absorbance and comparing it with the calibration curve. For example:
Concentrations and absorbance readings are as follows
0.5mg/mL=10 nm
1.0mg/mL=15nm
1.5mg/mL=20nm
2.0mg/mL=25nm
This data is plotted on a calibration curve. Next we measure the unknown substance the absorption is 20nm. We can suggest that the concentration is 1.5 mg/mL. If there are readings that fall inbetwen values then the formulat to calculate the right concentration would be y = mx + b, where m is the slope and b is the y-intercept.
Linear regression uses the modification of the slope formula y= a + bx to best see how the data of the water samples would fit on the slope of the calibration curve. X is the independent variable , b is the slope of the line and a is the y-intercept.
Extrapolation would be the action of calculating data that are outside the calibration curve, assuming the trend would continue.

<u>Answer</u>: please find below the correct matches
<em>vitamin E</em> - antioxidant that protects cells from damage and promotes healthy skin
<em>fiber</em> - carbohydrate that slows the absorption of sugars into the bloodstream
<em>calcium</em> - mineral found in every cell of the body and is involved in the formation of teeth
<em>phosphorous</em> - mineral involved in the process through which muscles contract and relax
<em>cholesterol</em> - lipid molecule produced by all cells in the body and that forms lipoproteins
I think the survival of the fittest. <span />
