Lets see this with example
if you put a red blood cell in a glass of water the red blood cell is in hypotonic solution and that water flows into less concentrated area ( in to the red blood cell ) which eventually will swell and burst.
Another plot is when we put the same red blood cell in a glass full of salty solution which is Heterogeneous solution. In these case the water will move out from the cell to the solution which cause the cell to shrink.
Evidence validates conclusion
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.
The answer to this question would be: smell
The sensory organ that catch smell is located in the nose and will send the signal into the olfactory bulb. The olfactory bulb is located in the bottom part of the brain, near the hippocampus(which was the center of memory), and amygdala (which was the center of emotion).
It’s A. Double stranded DNA consists of two polynucleotide chains whose nitrogenenous bases are connected by hydrogen bonds.
