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.
Growth, Development, and production of new cells??
hope im right
The picture doesn't mention mating or nesting - there is not a single mention of those. Therefore we cannot use answers 2) and 4), since we know nothing about them.
The same actually holds for 3) - while there is a mention of the beaks and you can infer the beak size, there is no connection between the beak size and mating activity.
so the correct answer is 1) -the type of beak is matched with the food.
I'm sure there are many processes that add to diversity, but the ones that stand out to me would be meosis, natural selection, mutation, random mating.
