<span>A food preservation method in which microorganisms metabolize components of a food is called </span>fermentation.
When the food is going on fermentation, there are good bacteria over there that will inhibit other bacteria to grow on that food. Fermentation also able to made the pH more acid, making the area is not suitable for bacterial growth.
Covalent bonds allow carbon atoms to form numerous compounds.
Answer:
Cells vary greatly in shape These shapes are often related to the function they perform. like the disk shape of erythrocytes can absorb and transport oxygen due to increased surface area., the amoeboid shape of leukocytes allow them to squeeze through capillaries. etc.
Explanation:
Cells can be disc-like , polygonal, rectangular, cubopid thread like branched or even irregular. these are related to the functions that each cell performs.
Some examples showing relation between cell shape and function are as follows.:
- Human blood cells are circular and biconcave to transport oxygen.
- White blood cell are amoeboid to squeeze through thin capillaries.
- Nerve cells are long so that they can carry nerve impulse to a long distance very quickly.
- Guard cells of stomata are bean or dumbell shaped to open and close the stomata.
