The correct answer is option E. "None of A-D is false; all are true statements".
Explanation:
The standard plate count involve different considerations including the ones listed:
A. It utilizes a standard dilution procedure called serial dilution. Most of the time culture plates have thousands of cells growing in it, it is necessary to use a standard dilution in order to make the counting feasible.
B. It measures both live and dead cells in the liquid sample. The standard plate count procedure uses a dye such as crystal violet to differentiate among live and dead cells. Both should be counted and the percentage of viability should be reported as well.
C. A countable plate in the procedure is one having 30 to 300 CFUs on it. Between 30 to 300 CFU is considered a countable plate since less than 30 will be make errors in dilution to be considerable and more than 300 is difficult to count and tend to form cell aggregates.
D. It is a viable count method to quantitate cell density of a liquid sample. This is true as long as the cells in the liquid sample are able to growth in a standard plate as well, since the cells must adhere to the counting device in order to perform the procedure.
Answer:
(1) The Pampas and (2) The Patagonia
Explanation:
The Pampas are the extensive flatlands that are abundant and highly fertile area surrounding the Buenos Aires. It forms a grassland biome. The climate here is warm and humidity is high. It covers an area of about 780,000 sq. km, i.e. the area between the Atlantic ocean and the Andes Mountain. Some of the animals found in these flatlands area are bush dogs, foxes and various other bird species.
The Patagonia grasslands are the small region located in the southern part of Chile and Argentina. This region is highly rich in the animal species and various other endemic bird species. This area mainly occupies the low terrain mountains, along with some plains and plateaus. The soil here is highly rich in organic material and the average rainfall in this region is between 300 to 400 millimetres every year. Due to the overgrazing by sheep, these grasslands are affected. Some animals found in this region are foxes, patagonian mara and guanaco.
Answer:
<u><em>please mark brainliest!</em></u>
Explanation:
<u><em>Polymers are broken down into monomers</em></u> in a process known as hydrolysis, which means “to split water,” a reaction in which a water molecule is used during the breakdown. During these reactions, the polymer is broken into two components.
Carry nutrients from the soil to the plant
