Explanation
Organisms from kingdom Plantae does have cell walls. Organisms from Animalia does NOT have cell walls. Fungi also does have cell walls. Prokaryotic Eubacteria includes bacteria with cell walls. Therefore, the organisms with cell walls are I, III and IV. The correct answer is C.
Answer
C. I, III, IV
Answer:
Passive transport requires energy and moves materials from areas of relatively lower to higher concentration. Passive transport dose not require energy and moves materials from areas of relatively lower to higher concentration
Answer:
1. Archaebacteria: They are single celled and thrive in extremely hot environments
2. Eubacteria: They are very commonly known to people as parasites like Streptococci, which causes strep throat. However, they can also help produce many antibiotics. They are also single celled
3. Fungi: They are multi celled organisms that are most recognizable as mushrooms, molds, mildews, and yeast.
4. Protista: They are single celled organisms that are much more complex than single celled bacteria. They are most recognizable as algae and slime molds.
5. Plantae: This kingdom is made up of flowering plants, mosses, and ferns. They are multi celled and complex.
6. Animalia: This kingdom is the largest out of all of them. It is made up of complex, multi celled organisms.

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.
<em><u>Andesite:</u></em>
<em>Is an extrusive igneous, volcanic rock, of intermediate composition, with anphanitic to porphyritic texture. In a general sence, it is the intermediate type between basalt and decite and ranges from 57 to 63% silicon dioxide as illustrated inTAS diagrams.</em>
