Answer:

Measurement (Count) of Cell Numbers:

1. Breed Method:

A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.

Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.

olasank [31]

Selective adaptation is when we view a stimulus with a specific property, and the neurons tune to that property fire, eventually becoming fatigued.

Neurons tune to a particular attribute fire when we see a stimulus with that property; over time, this firing fatigues the neurons or causes them to adapt. The neuron's firing rate drops due to this adaptation and fires less often when the same stimulus is provided to it again right away.

For instance, a page of plain black text on a white backdrop will undoubtedly capture your attention and make it easier for you to identify important information. However, if you keep viewing pages and pages of mainly neon pink highlights, you'll probably grow accustomed to them, and they will eventually stop drawing your attention.

Volgvan

Answer: The correct answer is option C.

Explanation:

A false negative test is a diagnostic error in which a test shows absence of a disease even when a person is having a disease.

Similarly, in the given question a sample has anthrax spores; however, antibody test fails to show the presence of anthrax. Thus, it is a false negative.

In contrast, false positive error is the error in which the test shows the presence of disease even when a person is not suffering from it.

Sampling error is a statistical error.

Thus, the correct answer is option C.
