Answer:
"Yes" The streak plate method is very effective in diluting the population size in all 4 plates.
Explanation:
The streak plate method is effective because it is one among the rapid isolation method which further allows for easy observation of the bacteria. This method is also being used for getting the color of the certain substances. Its main principle is to isolate the specific bacteria from the sample of various microbes. It dilutes the microbes number and often reduces their density. It is useful in separation of organisms from the group. These are isolated in the agar plate.
The amount of energy available from the organisms within a tropic level determine the carrying capacity of the next tropic level

<h2>Answer is option "b"</h2>
Explanation:
- Non-ionizing radiation is radiation that has a lower frequency, or longer wavelength, in the EMR spectrum. These frequencies range from that of power lines, radios, and cell phones, up to visible light. Non-ionizing radiation is not powerful enough to break the chemical bonds in molecules. In general, it is not harmful to human health as radiation per se, but could be harmful in terms of the transfer of heat energy. An example of an emitter of non-ionizing radiation is a microwave oven.
- Non-ionizing radiation is less harmful because the rays carry much less energy. Radio waves, light, and even heat are examples of non-ionizing radiation. For the most part, these kinds of radiation do not cause any damage. However, ultraviolet light is a kind of non-ionizing radiation that can be harmful - it can cause mutations in DNA
- Non-ionizing radiation is limited to the lower energy range electromagnetic radiation, which is more commonly known as light. However, the light we can see with our eyes, visible light, is only a small section of the electromagnetic radiation spectrum as seen here
- Hence the right answer is option "b"
The four characteristics of a mineral are:
1. Cleavage- the way it breaks, whether flat or roughly.
2. Luster- the way light reflects off of it, i.e. pearly, shiny, etc.
3. Streak- the color that its powder is
4. Hardness, for example, diamond is the hardest mineral, this is usually measured on the Mohs scale.
