Answer: Swimming
Explanation:
The swimming motility is one of the type of bacterial movement. This bacterial movement is mediated by the rotating flagella. It takes place when the individual cells move in the liquid environment.
The phase contrast microscope is used to the enhance the contrast of the images formed by the ordinary light microscope. This can be used for observing the transparent and colorless specimens. The phase contrast microscope enables the visualization of the cells and their organelles that would be difficult to observe under the ordinary light microscope.
The phase contrast microscope can also help in observing the swimming motility of the bacteria. This can be used to observe the change in directions of the bacilli under microscope.
Answer: Kingdom Animalia (Multicellular Heterotrophs)
Explanation:
Heterotrophs (animals) cannot make their own food like the green plant (autotrophic mode of nutrition). So they have to search for foods by moving about. They can feed in plants, other organisms /animals or feed on dead materials.
Animals are multicellular (with many specialised cells). For example the cell in our nose are meant to respond to smell while that of the eyes are specialised for light capture. Our muscle cells focused on movement. Unlike the plants, animals lack cell walls.
cholecystokinin is the answer, good luck!
<span>all of the above are </span>a possible cost of using renewable resources, though loss of animals species is a negative factor but still it counts.
