Answer:
Explanation:
As a microbiologist there are different methods are devised for characterization of microbes.such as Macroscopic analysis and microscopy method.
With the help of microscope the needed information about the individual cell such as individual cellular characteristics can be obtained, the magnification help to provide the features such as size, shape and motility of the microbes which helps to know the specific microbes characters.
When handling an unknown environmental microbe, with help of the cell characteristics of the microbes obtained using the microscope, the identity as well as metabolic characterization can be known such as the type of environment the microbes can survive in(aerobic or anaerobic), the source of food.
No growth was observed on the control plate.
The growth on the control plate indicates that the aseptic technique devised in the model was an adequate method for the prevention of the control plate from been contaminated.
Answer:
False
Explanation:
Two or more elements combine to forma COMPOUND.
Answer:
there were only anaerobic heterotrophic bacteria (the primordial atmosphere was virtually oxygen-free).
Answer:
D. decreasing in population.
Explanation:
Triggerfish are the brightly colored fish and sea urchins are the globular animals, echinoderms. Triggerfish eat sea urchins for their survival.
An increase in the use of recreational boats over the area will damage the habitat of the triggerfish and also affect their food supply, it will result in a decreasing population of triggerfish. Due to lack of sea urchins and habitat disturbance, the Triggerfish population will decrease
Hence, the correct answer is "D. decreasing in population."
