Explanation:
Groundwater is the freshwater present below the earth's surface. It originates from the rain, ice, melting snow.
Some anthropogenic sources of groundwater pollution are
Groundwater pollution has more problems than surface water pollution because groundwater is mostly hidden and it is very difficult to view, manage and monitor.
Groundwater holds its contamination and pollutants that cause pollution whereas surface water rinses their contamination and pollutants.
Heredity is the passing of physical characteristics unto the next generation a mouse for example might have brown fur the mouse he "gets busy with" also has brown fur likely hood of the baby having brown fur is a high likley hood hence you can say that the baby mouse has brown fur because of the heredity of his parents<span />
Benjamina has walked two legs of a right triangle, so you can connect her two movements with a line if you were sketching the situation.. The displacement is the objects overall change in position in relation to its origin, so in your case, Benjamina's apartment. While the total distance adds up regardless of her position.
So, the total distance Benjamina walked is 10m + 6m = 16m
Her displacement can be found by your best friends, the Pythagorean Theorem: 10m ^2 + 6m ^2 = delta x^2 (or displacement squared).. giving you a displacement of 11.66, or 12 m
The difference between the distance she walked and her displacement is 4 meters.
Answer:
The original water sample contains 830,000 cells per milliliter.
Explanation:
A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.
