Answer:

During osmosis the water moves from a solution with a low concentration of solute to a solution with a high concentration of solute.

Explanation:

Osmosis is the movement of water that occurs within cells through a semipermeable membrane. This process is carried out from a medium with a lower concentration of solute to another with a higher concentration.

In osmosis, the solvent (water) is passed from one medium to the other. This process does not take up energy and, therefore, osmosis is considered a passive transport.

In the process of osmosis, water, which is the solvent, tends to cross the semipermeable membrane in order to balance the concentration of the solution. This action is performed until the osmotic pressure is stabilized.

Thus, osmosis occurs whenever there is a difference in concentration between the external and internal environment of the cell. In this case, the water goes from the least concentrated region to the most concentrated one, naturally.

The result of osmosis is used in the nutrient exchange processes of animal and plant cells.

In what order do the changes in the succession of an ecosystem occur?
wlad13 [49]

An example of succession is a landslide is produced, then lichens grow, this leads to the accumulation of thin soil, which finally leads to a mature community.

<h3>What is succession?</h3>

Succession is an ecological process associated with the renewal of the ecosystem after a disturbance.

The process of succession is fundamental for reaching the homeostasis (internal equilibrium) of the ecosystem.

The succession may involve the emergence of new species in the ecosystem after disturbance.

4 a muscle cramp is a sudden, painful contraction of a muscle, during which movement is difficult. What is happening at the cell
stiks02 [169]

In the case of the muscular cramps, the muscle contraction starts with the generation of the action potentials from the brain. The action potential causes the release of the calcium ions movement out of the sarcoplasmic reticulum (storage site of calcium). The calcium released in this process causes the contraction of the myofibrils with the help of the ATP molecules. Meanwhile, the calcium is pumped back to the sarcoplasmic reticulum through the fast calcium pumps.  

The contraction of one muscle cell generate the action potential in neighboring muscle cells. When the generation of the action potential is stopped, the sarcoplasmic reticulum relaxes as well as the muscle is relaxed. The fast calcium pump is powered by a sodium gradient, and the calcium influx is a result of fast outflux of the sodium ions from the sarcoplasmic reticulum.

In case, the sodium ion is less, the calcium pumps cannot be powered, the calcium ion would remain in myofibril, as a result, the muscle would be contracted for a longer time and this result in cramps. The muscle in this case, would be relaxed by the ATP instead of sodium gradient. So, it can be concluded that the muscle cramps are caused when the muscles are not able to relax properly.
