The cells won’t be able to efficiently get what they need and that will disrupt processes such as cell respiration or photosynthesis. If you are talking about cell membranes, then the organisms won’t be able to function Bc the cell membrane compartmentalizes the cell to see that everything runs efficiently
An example of homeostasis would be sweating when the temperature is hot.
Answer:
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
Explanation:
The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).
The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.
Hence, the correct option is D.
As we have studied in junior classes <em>that all animals including bacteria contain a plasma membrane around their cell which controls the movement of water and materials to and from the cell.</em>
The bacteria are the main hazard in pesticides and if we study about its structure, it contains both cell membrane and cell wall. Now another point in that bacteria lives in a moist or hypotonic environment in which the concentration of water inside the cell is less than the concentration of water outside the cell. This results in more movement of water from outside to inside the cell since we know that water moves from a place of higher concentration to a place of lower concentration.
Now when the water moves inside the bacterial cell, it can burst bacterial cell but thanks to the presence of cell wall which donot lets the burst caused.
So coming towards sugar solution, when bacteria are dipped in dilute sugary , the outside environment around a cell is sugary, and the concentration of water in the solution is less than inside the cell and water tends to leave the cell. the major effect of sugary solution is that it withdraws water from inside the body of micro organisms if the external concentration of sugar is high enough. When the water will move out of their body, they will die and their spores will not be able to germinate too.
This will eventually make our food (vegetable, fruit or any other) clean.
Hope it helps!
Answer:
False.
Explanation:
Note that, osmosis is considered as the passive movement of water because,it involves the movement of water from a region or area where concentration is high to the region or area of low concentration. This is the reason why it is compared to or described as a type of diffusion.
This process is known as passive transport or passive movement of water. And it is known to be water specific process.
That is why it can be compared to diffusion of ions or other small molecules in physics.
