There are both physical and biological limiting factors found in nature.
-Physical factors (abiotic factors) include temperature, water availability, oxygen, salinity, light, food and nutrients.
-Biological factors (biotic factors) involve interactions between organisms such as predation, competition, parasitism and
herbivory.
I don’t see the “following” that ur talking abt but it is diffusion
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.
I had to look for the options and here is my answer.
The GINGKOS, GNETOPHYTES and CYCADS are the closest relatives of the familiar pine and spruce trees. These plants are coniferous and belong to the plant <span>family Pinaceae. They are coniferous in a way that they produce hanging cones and have needle shaped leaves.</span>
Answer:
Facultative anaerobe
Explanation:
A facultative anaerobe is an organism that commonly grow in the presence of oxygen and use aerobic process to form ATP and to gain energy but they can also grow in the anaerobic condition by getting energy from fermentation process.
As anaerobic condition is not the perfect condition in which facultative anaerobe wants to grow because they prefer more to grow in aerobic conditions, therefore, their growth is not that much high in anaerobic condition as compared to aerobic conditions.
Therefore they show moderate growth in the culture present in candle jar and anaerobic jar because oxygen is absent there but show heavy growth in the culture present in a standard incubator because of the presence of aerobic condition here.
