Answer:

The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.

Explanation:

According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.

The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.

Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.

Answer:

i would like to choose sublimation process to explain about water cycle.As mentioned, sublimation is the process in which snow melts and water get vaporized. Ice melts and turns into water which flows to the seas and oceans.When the temperature increases during the day time, water gets vaporized.Water vapour begin to move upward.As we know, temperature decreases with the increase in height.Due to which water vapour rises,cools and then changes into tiny water molecules.Those water molecules forms cloud.Then the clouds get heavier and begin to collide with each other.As a result rain fall occurs.

Evapotranspiration has also the same process but the difference is that it involves vaporization of water from some biological factor like plants and physical factor like from soil .

i think its my first longest answer which i answered here.Thank you for the amaizing question. Its simple but most important topic

Answer:

The ability to maintain a reasonably steady internal state that persists despite changes in the external environment is known as homeostasis. To utilize energy and eventually survive, all living species, from plants to puppies to humans, must manage their interior environment.
