D.Osmosis
Answer:
osmosis
Explanation:
on edge2020
The movement of water from an area of high water concentration to an area of low water concentration is called as Osmosis. Thus option D is correct.
What is osmosis ?The process in which solvent molecules pass from a lower concentration based solution to a higher concentration solution through a semipermeable membrane called as osmosis.
It is a passive process as no external energy is needed.
When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as ex-osmosis.
The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.
When the plasmolysed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.
This condition is called deplasmolysis or cytolysis. Thus option D is correct.

why do plant need food
Answer:
They need food in order to gain the initial energy they need.
Explanation:
Plants unlike humans don't get food by primary sources (aka, hunting). instead they retrieve their food from the suns rays. Without the suns rays they are able to convert this energy into glucose for themselves, and will essentially die because they do not have that source of food to give them the energy they need to survive.

An engineer made a model of a ship to help him think about how it works ha made sure that some characteristics of the ship were accurately represented but he did not include all of the ships characteristics in his model is it okay that he ignored some of the ships characteristics
Answer:
Yes it is ok
Explanation:
This usually depends on what the engineer is trying to accomplish or learn. For example, if the engineer is simply trying to understand how the architecture floats or cuts through the water then he does not need to model the engines or other unnecessary characteristics. On the other hand, if the engineer wants to understand how the engine provides power to the entire ship then he would need to model the engine and all the connected parts but not the outer exterior of the ship. Therefore, it is ok that he did not model the ship completely as long as it provides the information needed.
