Answer:
Taking into account the principle of osmosis, the question that best addresses experimental design is <em>How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?</em>
Explanation:
The experimental design of the student, made with dialysis bags and sucrose at different concentrations should recreate the principle of osmosis, of importance in living beings for organic homeostasis.
Osmosis consists of the movement of water - through a semi-permeable membrane - from a less concentrated solution to a higher concentration solution, following a gradient, to achieve balance.
The student will observe in his experiment that water moves from the solution with less sucrose concentration to the higher concentration of sugar. Beakers with the highest concentration of sucrose will have the highest weight, due to the increase in liquid volume.
How does the effect of environmental sucrose concentrations impact the movement of water across a membrane?
The experiment shows that:
- The water from the beaker with less sucrose concentration moved -through the dialysis tubes and the membrane- to the beaker containing the most concentrated sucrose.
- Different sucrose concentrations will attract different amounts of water, which influences the final weight of each container.
With this experiment the principle of osmosis is confirmed, where the concentration of a solute determines the amount of water that passes through a semipermeable membrane -following a concentration gradient- until equilibrium is reached.

- Consisting of, involving, or comprising nerves or nerve cells.
<h3>What functions does the nervous system perform?</h3>
Your nervous system uses neurons, which are specialized cells, to send impulses and messages throughout your body. Your muscles, organs, glands, skin, and brain all send and receive electrical signals. The communications allow you to move your limbs and feel things like pain.

Explanation:
1 gallon [US, liquid] to litres = 3.78541 litres
5 gallon [US, liquid] to litres = 18.92706 litres
10 gallon [US, liquid] to litres = 37.85412 litres
15 gallon [US, liquid] to litres = 56.78118 litres
20 gallon [US, liquid] to litres = 75.70824 litres
25 gallon [US, liquid] to litres = 94.6353 litres
30 gallon [US, liquid] to litres = 113.56235 litres
40 gallon [US, liquid] to litres = 151.41647 litres
50 gallon [US, liquid] to litres = 189.27059 litres
we could tell that 2.2 gallons are in between 8.327906 litres
Carbon is released by all except <u>precipitation</u><u>.</u>
Hydrogen bonds exists between the DNA strand and its complementary strand such that; there are two hydrogen bonds between every A and T, and three between every C and G.
Therefore; in this case there will be (2 ×3 ) +(3×3) = 15 hydrogen bonds for the above strand. this is because Adenine binds to Thyamine with two bonds (3 pairs) and Guanine binds to Cytosine with three bonds (3 pairs).
