<span>The cell would swell and burst, because the 20% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell. Example, water moves from the blood filtrate that will form urine. The same will do while pure water moved to seawater.</span>
A isotope is atoms of the same element with different amount of neutrons to change the mass. They can become more stable by sharing or giving away electrons to have a stable electron shell
The correct option is C.
Kelp are brown large algae, which live in cool, shallow water, close to the shore. Because they depend on light for photosynthesis, they usually inhabit shallow open water and they are found at depths that is not greater than 131 feet.
Low friction between you/the ski vs the snow.
if you think about it its kinda like you and a slip and slide...water helps decrease friction so you slide (snow does the same for the skiing) but without it you just flop and don't go anywhere (very easily anyway).
Answer:
A catalyst decreases the activation energy of a reaction.
Explanation:
A catalyst allows a reaction to go through a new pathway that has a lower activation energy. Therefore, it will recquire less energy to reach the transition state (activated complex) which increases the rate of the reaction. This is the reason why adding a catalyst makes a reaction faster.
The figure attached shows the graphical representation of the effect of a catalyst on the activation energy.
