Which part of the cell was most directly responsible for the shrunken appearance of the cell?
Answers
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.
What is osmosis ?
Osmosis is the net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
This may sound odd at first, since we usually talk about the diffusion of solutes that are dissolved in water, not about the movement of water itself.
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.
In an isotonic environment, there is no net water movement, so there is no change in the size of the cell.
When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
Therefore If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink.

Answers
Boyle's law gave the relation between the pressure and the volume of the gas. The equation can be represented as PV = constant (T and n are constant).
What is Boyle's law?Boyle's law gave the inverse relationship between the pressure and the volume of the hypothetical ideal gas when the moles and the temperature are constant. It can be shown as PV = constant.
The volume of the gas can be compressed by increasing the pressure, and the volume of the gas can be expanded by decreasing the pressure of the gas.
Therefore, Boyle's law gave the PV = constant.

Based on log rules and the way ph is calculated, what is the difference in [oh– ] concentration between point a and point b. 101 105 106 107
Answers
Based on their pOH values, the difference in [OH– ] concentration between point A and point B is 10^6.
What is pH of a substance?The pH is determined by the concentration of Hydrogen ions [H+]. The higher the concentration of H+ ions, the lower the pH of a substance. If the concentration of H+ is greater than OH-, the material is acidic, i.e. the pH value is less than 7
In this case, the formula for this will be:
[tex]pH= -log[H+][/tex]
So we have:
[tex][OH]= 14-1= 10^{-13}\\[OH] = 14-7=10^{-7}[/tex]
Therefore, the difference in [OH– ] concentration between point A and point B is 10^6.

This question involves the concept of binding energy.
The amount of energy released by this reaction is "a) 1.22 x 10¹³ m/s".
What amount of energy is released?The amount of energy that is released during the radioactive decay of any element is known as binding energy. This can be given by using the following formula:
[tex]E=\Delta mc^2[/tex]
where,
E = energy released = ?Δm = mass change = 0.135 g = 1.35 x 10⁻⁴ kgc = speed of light = 3 x 10⁸ m/sTherefore,
E = (1.35 x 10⁻⁴ kg)(3 x 10⁸ m/s)²
