The correct answer to this is:
<span>Chondroitin sulfate is abundant in the matrix of <u>“Cartilage”.</u></span>
<span>A 1 unit of Chondroitin sulfate has a chemical formula of
C</span>13H21NO15<span>S. It is
usually found attached to proteins as part of a proteoglycan and is a vital
structure of cartilage by providing much resistance to compression. Due to
this, this chemical has found wide use as a dietary supplement for treatment of

Answer:
NH4+
Explanation:
NH4+ is the acid and NH3 is the base, so NH4+ is the stronger acid.
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.
4FeS2 + 11O2-> 2Fe2O3 + 8SO2
Not sure.... I think this is it
Answer:
A. While inconsistent, his average of 1.0 kg made his results quite
accurate
Explanation:
Accuracy is how close the value you gain from test or observation compared with the real value. In this test, all tests relatively close to 1kg and the average of the test is 1kg so this tool can be considered quite accurate.
The precision determines how close the value of multiple repetitions of the test. In this case, the value varies from 0.8kg to 1.2kg. The highest value is about 50% higher than the lowest value, so the range is pretty far and the test can be considered not precise.
