What are the three basic functions organs perform in the human body
77julia77 [94]

Answer:

There are several different ways to name it, but I always go by absorption, digestion, and metabolism/breakdown.

Explanation:

Absorption is the uptake of minerals, vitamins, and nutrients from your diet and your ingestion of water or other liquids. Absorption primarily takes place in the small intestine and anything that isn't necessary and vital for human life is then excreted through the urinary tract as urine and the remainder of the digestive tract as waste/feces.

Digestion is the process that occurs in the digestive tract which breaks down all food intake by mechanical and enzymical (stomach/gastric acid) processes in order to provide the body with all of the nutrients and minerals it needs to survive.

Metabolism is the breakdown of acids, fats, and enzymes within the organs in order to maintain life and promote production of energy. A healthy diet, cardiovascular exercise for 4-5 days a week, and maintaining good health in general is best to maintain a high metabolism and produce the most energy.

If a bacteria is positive for the enzyme urease and is inoculated in a urea reduction broth tube at 37∘C for 24 hrs, what color
Vedmedyk [2.9K]

Answer:

The color would be Pink

Explanation:

According to the question, the bacteria is positive for the enzyme urease and it's inoculated for 24 hours.

Urease broth is a differential medium that tests the ability of an organism to produce urease, that hydrolyzes urea to ammonia and carbon dioxide. The broth contains two pH buffers, urea, a very small amount of nutrients for the bacteria, and the pH indicator phenol red. Phenol red turns yellow in an acidic environment and fuchsia in an alkaline environment.

If the urea in the broth is degraded and ammonia is produced, an alkaline environment is created, and the media turns pink within 24 hours.

Many enterics can hydrolyze urea; but only a few can degrade urea rapidly. These are called “rapid urease-positive” organisms.

Urea broth is formulated to test for rapid urease-positive organisms. The restrictive amount of nutrients coupled with the use of pH buffers prevent all but rapid urease-positive organisms from producing enough ammonia to turn the phenol red pink.
