Answer:
It maintains body temperature by absorbing energy
Explanation:
I hope it will help ☺️☺️
Answer;
Cells, bacteria, viruses, DNA
Explanation;
-A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. It useful for studying details of a specimen's surface.
-An electron beam passes over the specimen's surface and displaces electrons, which are then focused on a screen to form an image. Uses a conductive material (gold metal) on the specimen.
-The scanning electron microscope gives much higher clarity of a specimen being viewed than the light microscope can; therefore, internal structures of cells, such as organelles, DNA can be viewed in much more detail. Bacteria and viruses can also be viewed in details and studied under a scanning electron microscope.
This whole is experiment is called the Kirby Bauer disk diffusion method. It is testing the susceptibility of microorganisms to disinfectants to see which disinfectant works the best against killing the bacteria.
By asking which is the control it would mean the experiment is unaffected and kept the same.
That means the answer is C because water does not affect the bacteria
The aquatic animal's respiratory system is different from the human respiratory system because the aquatic animals have gills while the human has lungs.
<h3>What is respiratory system?</h3>
The respiratory system is one of the major systems of the body that helps in the intake of oxygen and removal of carbondioxide as waste products from the body.
The aquatic animals are those animals that live, reproduce and survive in the water while human survive in the terrestrial ecosystem.
Due to the difference in the ecosystem existing between the aquatic animals and humans, they have different respiratory system that functions differently too.
The aquatic animals possess gills which can absorb oxygen from water while the human has lungs which allows the diffuser of oxygen with release of carbon dioxide.
