The right answer is A.
Osmosis is a phenomenon that considers only the exchanges between two liquid solutions of different concentrations in liquid phases separated by a semi-permeable wall. Osmosis is a phenomenon of diffusion of matter, demonstrated when solvent molecules pass through a semi-permeable membrane separating two solutions whose solute concentrations are different; the overall transfer of solvent is then from the least concentrated solution (hypotonic medium) to the most concentrated solution (hypertonic medium) to equilibrium (isotonic media).
The diffusion of matter, or chemical diffusion, refers to the natural tendency of a system to render uniform the chemical potential of each of the chemical species it contains.
Chemical diffusion is an irreversible transport phenomenon that tends to homogenize the composition of the medium.
Answer:
cell membrane
Explanation
It's the outer living boundary of animal cells. It's made of lipid and protein. Plasma Membrane is a mosaic of phospholipids, cholesterol, and proteins, the proteins in plasma membrane regulates the coming/going of substances into/out of the cell.
answer:
photosynthesis converts energy into carbon dioxide and water into oxygen and glucose. glucose is used as food by the plant and oxygen is a by-product . cellular respiration energy into glucose into water and carbon dioxide
water and carbon dixode are by products and ATP is energy hat that is transformed from
4. Large, circular lily pads are able to float on the water's surface.
Answer: cohesion
Cohesion mean that water attracted to another water. This force will make the water to form a surface tension in the lake. Water lily has a wide and thin leaf which makes it giving a low force per area. If the force applied on the surface is not bigger than surface tension, the leaf will stay float above the water. Surface tension also the reason water spider could walk on water.
5. The temperature of the water is about 5°C, while the temperature of the air is about 21°C.
Answer: heat capacity
Water has high heat capacity. High heat capacity mean that the water will not be easily become cold or hot. It will need more energy to increase/decrease the temperature of the water. This is why the water could keep its temperature much lower than the atmosphere. This will protect the organism inside the water from an extreme temperature change.
The rock layer on the bottom will decompose and either turn to sand, gravel, or blend in with the dirt (but most likely not the last one).
