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.
Answer:
Sedimentary rocks
Explanation: Where are fossils found? Fossils are found almost exclusively in sedimentary rocks—rocks that form when sand, silt, mud, and organic material settle out of water or air to form layers that are then compacted into rock. So the answer will be <em>Sedimentary</em> rocks.

HANS SELYE was the one who defined stress in this way.
Hans Selye is an endocrinologist and a famous stress researcher. He was the first scientist to write about the general adaptation syndrome which he used to explain his stress model. His model put it forward that an event which threaten the well being of a living organism leads to three stage bodily response which are alarm, resistance and exhaustion stage.
T<span>chromatins make up </span>chromosomes<span>. Chromatins are just a combination of DNA, histones(a type of proteins) and RNA. Strands of DNA are considered as chromatins and when these strands combine, this forms the </span>chromosome<span>. </span>Chromatin<span> is untangled and unfolded DNA, while </span>chromosome<span> is condensed DNA. T</span>he chromatin, dispersed in the nucleus, is a set of filamentous DNA molecules associated to nuclear proteins called histones. Each DNA filament is a double helix of DNA and thus a chromosome.
