Answer:
Explanation:
Escherichia coli, is a type of bacteria that lives in the intestines. It's also found in the gut of some animals. Most of them are harmless, they aid keeping the digestive tract healthy. Though if contaminated food or fouled water is consumed, some strains can cause diarrhea .
Catalase enzymes, hydroperoxidase I (HPI) and HPII, catalyze the dismutation of hydrogen peroxide to water and oxygen but they play crucial roles in protecting cells against the effects of oxidative stress.
Some examples of pathogenic microorganisms which produces catalase include staph, bacillus, aureus,etc
Test Procedure:
- With the aid of a loop or sterile wooden stick, a small amount of bacterial colony should transferred onto the surface of clean, dry glass slide .
- A drop of 3% Hydrogen peroxide should be placed on to the slide and mixed.
- A positive result is indicated by the rapid evolution of oxygen gas (within 5-10 seconds), which is evident by bubbling, while a negative produces no bubbles or only a few scattered bubbles.
- The used slide should be disposed in the bio hazard glass disposal container.
This is known as the Norm of Universalism. There are four scientific norms that apply to the pursuit of science. The other three are the Norm of Organized Skepticism which states that no scientific theory or finding is immune to questioning, the Norm of Communalism which states that all scientific knowledge should be made available to everyone and the Norm of Disinterestedness which states that scientists should seek truth not personal gain.
In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are the amount of water and temperatures. Terrestrial ecosystems rely on the sun's energy to support the growth and metabolism of the organisms. Plants use the sunlight, then they supply the organisms that are higher up the food chain with energy and the structural buildings blocks of life. Water is also essential for the survival of these organisms.
Answer:
<h2>
<u>Humans</u> : Through photosynthesis, humans can again breathe in the oxygen that was produced and survive. ... In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and </h2><h2>humans help plants "breathe" by providing them with carbon dioxide</h2>

<h2>
ANIMALS : </h2><h2>Photosynthetic organisms take light energy and use it to make their own "food". In this process they use </h2><h2>carbon dioxide and light to make sugars and oxygen. This is great for other animals that utilize this oxygen and eat the plants for food.</h2><h2 /><h2>(*˘︶˘*).。*♡</h2>
