Because they are different they all show different traits
Answer:
The unknown solution had the higher concentration.
Explanation:
When two solutions are separated by a semi-permeable membrane, depending on the concentration gradient between the two solutions, there is a tendency for water molecules to move across the semi-permeable in order to establish an equilibrium concentration between the two solutions. This movement of water molecules across a semi-permeable membrane in response to a concentration gradient is known as osmosis. In osmosis, water molecules moves from a region of lower solute concentration or higher water molecules concentration to a region of higher solute concentration or lower water molecules concentration until equilibrium concentration is attained.
Based on the observation that when the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises, it means that water molecules have passed from the glucose solution through the semipermeable membrane into the unknown solution. Therefore, the solution has a higher solute concentration than the glucose solution.
A triglyceride consists of a glycerol molecule and three fatty acid molecules in ester linkage to the glycerol molecule.
<h3>What is a triglyceride?</h3>
A triglyceride refers to a form of lipid found in fats stores in the body and which are produced during the digestion of fats.
Triglycerides are also known as triacylglycerols
A triglyceride molecule is composed of:
- a glycerol molecule
- three fatty acids which are in ester linkage with the hydroxyl group of the glycerol molecule.
Therefore, a triglyceride consists of a glycerol molecule and three fatty acid molecules in ester linkage to the glycerol molecule.

Answer:
D). She should use a bar graph. The bottom of each bar should be labeled with the category of garbage. The vertical side should have a scale and be labeled "kilograms per year."
Explanation:
Bar graphs are characterized as the graphic tool which are primarily employed to establish comparison between various groups or to observe the changes occurred over time.
As per the question, the environmental scientist must opt for the 'bar graph' as it will assist her in displaying the data of various categories(paper, yard waste, metals, etc.) through bars on the x-axis while the vertical side or y-axis would show 'kilograms per year' which will display the differences in their amounts. Thus, <u>option D</u> is the correct answer.
