In the viable plate count method, a measured volume of a culture is evenly spread across an agar surface and incubated. Each <u>colony </u>represents one <u>cell </u>from the original sample.
Explanation:
A viable count is the number of colony forming units (cfu) of microbes per gram or per milliliter of the sample, or cfu/gm or cfu/ml.
In order to find whether the cells counted is viable or not, methods like plate-count method, membrane-filter methods are used. These tests allow the visible cells to grow and multiply to check the viability.
The plate count method is done by growing the microorganisms like bacteria on a plate in a nutrient medium or substrate like the agar surface. The bacteria will grow into colonies and will be visible to the naked eye.
Each colony unit is counted and each unit in a colony represents a single cell of the bacteria or any microorganism cultured and counted.
The counting is done by various methods like hemocytometers, streak plate etc.
B- Enzymes act as catalysts to speed up chemical reactions
"Kinesis" is the one innate behavior among the choices given in the question that <span>are they displayed here. The correct option among all the options that are given in the question is the third option or option "c". I hope that this is the answer that you were looking for and it has actually come to your help.</span>
<span>Size and complexity are limited in systems usually by a combination of factors. Such as access to resources. Successful reproduction. Evolution over time dictates what is a successful balance in size and complexity in a system in its environment. If the resources are there and there is successful adaptation to the environment, systems can be supported that are extremely complex and also huge in size. Say the human body as a system.</span>
In the Arctic, growing conditions for vegetation vary greatly. In the southern parts of the Arctic, plant communities can be vigorous with small trees and stands of low growing shrubs.
The further north one travels, the shorter and more sparse the ground cover becomes until in the high Arctic, which is a true desert. Here, the plants are scattered across stony ground and the most numerous plants are the lichens. Also here the carpet of flowers are only found below bird cliffs or other areas of high fertility.
