Answer:
This question is incomplete
Explanation:
Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.
Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.
This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.
An example of a standard curve is provided in the attachment for guidance.

<u>Answer</u>: Dense regular (fibrous) connective tissue.
<u>Explanation</u>:
- <em>Connective tissue</em> is a tissue that performs various functions such as binding, connecting and supporting the other organs or tissues or separating one tissue from another.
- <em>Dense regular connective tissue</em> connects various tissues present in the body.
- Since the fibers are tightly <em>packed</em>, this tissue is <em>dense and fibrous</em>, and because the arrangement of the fibers is in <em>parallel</em> fashion, it is of the <em>regular</em> type.
"Denatures" is the word you are looking for!
By following honeyguides (a species of bird), people are able to locate bee's nests to harvest honey. In fact, research now reveals that humans use special calls to solicit the help of honeyguides and that honeyguides actively recruit appropriate human partners. this relationship is a rare example of cooperation between humans and free living animals.
