The primary consumer would be the rabbit because it feeds on the plants
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.
The correct answer is option A
The burning of fossil fuel releases carbon dioxide in the environment. Carbon dioxide is the main green house gas. The green house gases work by trapping the heat that comes inside the earth from the sun.
The carbon dioxide is the green house gas that traps maximum heat coming from the sun. If the carbon dioxide would not have been there then the temperature of the earth would have been very low and the atmosphere would have been colder.
But the global temperature is rising due to lost of carbon dioxide present in the environment as the burning of fossil fuels is increasing day by day.
Answer:
c. sound
Explanation:
Matter is formally defined as being any substance that has any amount of mass and takes up space by having volume. Dirt, Humans, and Water all have a different level of mass and take up a different level of space. Sound on the other hand does not have neither mass or volume, it is instead a wavelength or a constant vibration that travels invisibly through the air. Therefore it is not composed of matter.
