Which of the following is a function of the cell membrane of a cell? A. The production of energy from food molecules using cellu
lar respiration. B. The production of genetic material through DNA transcription. C. The transport of molecules into and out of the cell through osmosis and diffusion. D. The transport of genetic material within the cytoplasm of the cell.
The answer is C. If you want a good experiment on this place an egg in a glass of vinegar for 6 hours, remove and place into corn syrup for 6 hours, and finally remove and place into water for 6 hours. you’ll get a really good example of osmosis in different stages.
C. The transport of molecules into and out of the cell through osmosis and diffusion.
Explanation:
All cells have a structure called a plasma membrane or plasmalema, which acts as a barrier to prevent both the exit of cell content into the medium and the flow of any particle into the cell. The plasma membrane's main function is to transport molecules into and out of the cell through osmosis and diffusion in relation to the concentrations of salts and water inside and outside the cells. This characteristic therefore shows an important ability to select the structure, which can vary from 7 to 10 nm in thickness.
Mutualism can be defined as a type of symbiotic relationship.
Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
In the given question, some micro-organisms survive in the digestive tract of the cattle.
These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.
