Hydroponics is defined as the practice of growing plants without soil used to provide support or nutrients or ‘Soilless Farming'. How is ‘Hydroponics' an effective method of farming in arid and dry zones other Earth?
Answer:
Hydroponics solves the problem of unavailability of water in those arid and dry regions
Explanation:
As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.
This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.
However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.

A very thin slice is removed from a peanut and treated with Sudan III, another indicator that turns red in the presence of a lipid. Then the same slice is treated with Biurets reagent. When the peanut is examined under a microscope, little patches of red and blue-violet can be seen. What conclusions can be drawn from this examination? Why would you expect this result?
Answer:
Little patches
Explanation:
blue- violet
Little patches and blue- violet.
What is Little patches?Sudan III is a bis(azo) chemical that has a 4-[(2 methylphenyl)diazenyl]phenyldiazenyl group replaced at position 1 of the 2-naphthol ring. a fat-soluble dye that can stain some protein-bound lipids in paraffin sections and is mostly used to show triglycerides in frozen sections.
It functions as a histology dye, a fluorochrome, and a carcinogen. It belongs to the class of azobenzenes, is a bis(azo) chemical, and is a naphthol. It is similar to a 2-naphthol in terms of function.
"It certainly does not mean, as many writers have assumed, that the lipid in question belongs to the carbohydrate-containing glycolipid (cerebroside) group.
Therefore, Little patches and blue- violet.

Students in a biology class were discussing outbreaks of food-borne illness. Modern practices of refrigeration are aimed at curbing (limiting) these bacteria. They wanted to know exactly what happened to bacterial colony growth at varying temperatures. The teacher explained that scientists study bacteria in the laboratory by counting colonies that grow on plates filled with agar, which is a nutrient substance. “Design” an appropriate experiment that would test the effect of temperature on bacterial growth. You would have a period of 5 days to conduct an experiment.
Answer:
I know this isn't a big help answer, but you could use it as a start. You could say something like "I tested it in multiple different temps. including .... (any temps. you want) Then say how all of thoose different temps. changed the bacteria." I hope it helped! :)
Explanation:
Most of the foodborne diseases are caused by those bacteria that can grow well and infect food at normal temperatures, and their population can be controlled by lowering the temperature or raising the temperature too high, which can degrade their cell walls.
What is the effect of temperature on the bacteria?There are numerous bacteria that can infect food and cause foodborne disease when consumed by humans, resulting in diarrhea, stomach aches, and other symptoms. Because most of these bacteria grow at room temperature, keeping food at that temperature degrades it faster, so foods are kept and stored in the refrigerator. This low temperature keeps the cellular activity of bacteria low; as a result, the bacteria cannot produce toxins or grow their population.
Due to this, the refrigerator stores the food for a longer time. Different strains can be kept and stored at different temperatures on an agar plate, but a strain present at a low temperature will produce far fewer colonies than one present at a room temperature. Further the growth depends upon the types of bacteria.
Hence, by refrigerating the food, cellular activity is seized and controlled.

How does diagnosis explain why 1 ml of liquid from her small intestine digested protein slowly but 1 mg of her pure protease protein normally?
Answer:
Due to the absence of proteolytic enzymes.
Explanation:
The study diagnosis that small intestine digested protein slowly due to the absence or decrease quantity of proteolytic enzymes in the small intestine. Proteolytic enzymes are responsible to speed up the digestion process and after digestion amino acid is produced which is directly injected into the blood that is used by the body for the formation of muscles.
