1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.
2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.
3. The semipermeable membrane limits the diffusion of solutes in the water.
4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.
5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.

Answer:
<h2>Food is scarce year-round</h2>
Explanation:
Ectotherm, called cold-blooded animals, whose regulation of body temperature depends on external sources, such as sunlight or any other environmental source.
Example of Ectotherm are: fishes, amphibians, reptiles, and invertebrates.
Endotherm -called warm-blooded animals; those maintain a constant body temperature independent of the environment.
Example of endotherms ; include the birds and mammals and some fish are also endothermic.
Costs and Benefits of Endothermy
By Increasing the rate of metabolism is especially energy intensive. As a result, endothermic animals typically need more food than ectothermic animals.
Gravitational force: it is a force that attracts any objects with mass.
Buoyant force: it comes from the pressure exerted on the object by the fluid. Because the pressure increases as the depth increases, the pressure on the bottom of an object is always larger than the force on the top-hence the net upward force. The buoyant force is present whether the object floats or sinks.

Answer:
A
Explanation:
Wind is caused by inequal heating. As you should have learned, things expand when they get hot and contract when they get cold. So, the high pressure hot air flows into the low pressure cold air via wind.
Allergies (3) because they are the only disorder listed that is a result of the environment.
