Answer:
Water outside the cell will flow inwards by osmosis to attain equilibrium
Explanation:
In the hypotonic environment, the concentration of water is greater outside the cell and the concentration of solute is higher inside. A solution outside of a cell has a lower concentration of solutes relative to the cytosol.
If concentrations of dissolved solutes are greater inside the cell, the concentration of water inside the cell is correspondingly lower. As a result, water outside the cell will flow inwards by osmosis to attain equilibrium.
Osmosis is a process by which molecules of a solvent tend to pass from a less concentrated solution into a more concentrated one through a semipermeable membrane.
Answer:
2.82 L
T₁ = 303 K
T₂ = 263 K
The final volume is smaller.
Explanation:
Step 1: Given data
- Initial temperature (T₁): 30 °C
- Initial volume (V₁): 3.25 L
- Final temperature (T₂): -10 °C
Step 2: Convert the temperatures to Kelvin
We will use the following expression.
K = °C + 273.15
T₁: K = 30°C + 273.15 = 303 K
T₂: K = -10°C + 273.15 = 263 K
Step 3: Calculate the final volume of the balloon
Assuming constant pressure and ideal behavior, we can calculate the final volume using Charles' law. Since the temperature is smaller, the volume must be smaller as well.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 3.25 L × 263 K/303 K = 2.82 L
The plant will grow less than 5 centimeters because it is a seedless, non-vascular plant. The correct option is B.
<h3>What are moss plants?</h3>
Moss plants are those plants that do contain seeds or flowering plants. They are non-vascular plants, and they maintain the moisture of the soils. They are very small plants.
Moss plants are small plants that grow in moist and humid conditions. They do not need so much sunlight. They will grow less than 5 centimeters and wet conditions.
Thus, the correct option is B. less than 5 centimeters because it is a non-vascular plant.

Answer:
The correct option is option E
Addition to the carbonyl by a nucleophile is followed by loss of the leaving group.
Explanation:
Substitution reaction that involves nucleophile and acyl group is called nucleophilic acyl substitution reaction.
Generally alcohol, amine or enolate group act as nuceophile. The nucleophile displaces the acyl group of acyl haide, anhydride or ester.
Mechanism of acyl substitution reaction
First step is the addition of nucleophile to the carbonyl carbon results in the formation of a tetrahedral derivatives.
Second step is the removal of leaving group
Hence, the correct option is option E
Answer:
Explanation:
One: You could mix a small sample of it with a reactive metal. Underline small. You should see gas bubbles being given up. Usually the bubbles are hydrogen.
Example : K + HCl ===> KCl + H2
Two: You could use an indicator to watch it turn color as it goes from acidic to neutral. Litmus will go from red to blue under these conditions.
Three: Those are the two safest ways. If you knew the acid was dilute, you could put a small (underline small again) amount on your tongue. If it tastes like orange juice, it is likely an acid. This is a test every textbook mentions. You should never do it under any circumstances.
