Answer:

The correct answer is -

- to match the mystery food sample to a definite positive result (gelatin, oil.)

- to match the mystery food sample to a definite negative result (water)

Explanation:

Adding an indicator or any indicator to an unknown food sample or any sample and then adding the same indicator to the known sample is necessary to check and confirm the positive result and negative result that will help to match with the experiment result.

For positive result adding an indicator to get a definite positive result to mystery food for example gelatin or oil. Similarly for a definite negative result adding it to known food or water.

Name and explain three different ways micro-organism<br>Obtain energy

nikklg [1K]

Explanation:

photosynthesis

mutualism

decomposers

chemotrophs

photosynthesis:

Photosynthetic bacteria use the energy of the sun to make their own food. In the presence of sunlight, carbon dioxide and water are turned into glucose and oxygen. The glucose is then turned into usable energy

mutualism:

Some bacteria depend on other organisms for survival. For example, some bacteria live in the roots of legumes, such as pea plants. The bacteria turn nitrogen-containing molecules into nitrogen that the plant can use.

decomposers:

Bacteria known as decomposers break down wastes and dead organisms into smaller molecules. These bacteria use the organic substrates they break down to get their energy, carbon, and nutrients they need for survival.

The value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is: D. amount of material that has not decayed.

<h3>What is a radioactive decay?</h3>

A radioactive decay can be defined as a radioactive process in which an unstable atomic nucleus undergoes a spontaneous transformation into one or more different atomic nuclei and simultaneously emits radiation, accompanied with a loss of energy.

<h3>The types of radioactive decay.</h3>

In Science, there are three main types of radioactive decay and these include the following:

Alpha decay
Beta decay
Gamma decay

Based on the information provided in the table (see attachment), we can reasonably infer and logically deduce that the value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is the amount of material that has not decayed.
