Given what we know, we can confirm that the two organisms most closely related would be the human and the gorilla.
<h3>Why are the Gorilla and Human the most closely related?</h3>
Using only the information given from the diagram, we can say that gorillas and humans are the most closely related. Although the turtle and the chicken also share the same genetic similarities in the diagram, the human and the gorilla also share physical aspects between them, making them more related than the previous group.
Therefore, given that they share genetic and physical aspects, we can confirm that the two organisms most closely related would be the human and the gorilla.

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.
