Answer:
The sample mean is obviously different from the population mean, but tests of significance must be done to determine if the difference is statistically significant. The difference could possibly be attributed to chance or to sampling error.

Answer:
an advantage is living cells can be examined in their natural state without previously being killed, fixed, and stained
<h2>X-Ray diffraction</h2>
Explanation:
- x-ray diffraction and the macroscopic shape of crystals.
- X-ray diffraction is a nondestructive method generally utilized for the portrayal of smaller scale crystalline materials. The strategy has been generally applied for stage distinguishing proof, quantitative investigation and the assurance of structural flaws. Lately, applications have been stretched out to new territories, for example, the assurance of reasonably complex gem structures and the extraction of three-dimensional microstructural properties. This is the outcome of the higher goals of current diffractometers, the coming of high-power X-ray sources and the advancement of line-profile displaying ways to deal with conquer the line cover issue emerging from the one-dimensional information contained in a powder diffraction design.
The cortex which is composed of neurons and their supporting cells, and in living brain, has a gray color thus called the gray matter.
<span>Photosynthesis. Photosynthesis is a process whereby green plants and other organism like bacteria produce their food using organs like chlorophyll in plants and plasma membrane in bacteria to convert solar energy into chemical energy. The energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. Most plants, algae, and cyanobacteria perform photosynthesis. These organisms and plants produce organic waste product like water and Oxygen which is essentially for life on earth.</span>
