Answer:
Soil structure is defined by the way individual particles of sand, silt, and clay are assembled. Single particles when assembled appear as larger particles. These are called aggregates.
Explanation:
Aggregation of soil particles can occur in different patterns, resulting in different soil structures. The circulation of water in the soil varies greatly according to structure, Therefore, it is important for you to know about the structure of the soil where you plan to build a fish-farm. Although you may not be able to assemble all this information yourself, the specialized technicians from the soil testing laboratory will be able to provide it after examining your undisturbed soil samples. They will be able to tell you if your soil has bad structure or good structure (pores/capillary canals, network, etc.). They will also be able to tell you about the degree of water circulation or permeability.
Mutualism: <span>The bee and the flower. Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get some pollen on their bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating the plant. This benefits the plants.
</span>Parasitism: Fleas and dogs. <span>Fleas harm their hosts, such as dogs, by biting their skin, sucking their blood, and causing them to itch.
</span>Commensalism: The relationship between cattle egrets and cattle.<span>The cattle egret will eat insects that have been disturbed when the cattle forage. One species benefits while the other neither benefits or are harmed.
</span>Predation: The relationship between lions and zebras. The predator, the lion, kills and feeds on the prey, the zebra.
Competition: <span>One example of competition between two organisms would be chipmunks and squirrels. They compete for nuts to be able to feed themselves and survive.</span>
Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.
<span>The best things a nurse can teach a client when helping them to avoid exposure to lead in their lives is to stay away from any flaking paint, be mindful of the fact that lead can contaminate the soul, and it is possible for root vegetables to have more lead in them than other types of veggies.</span>
Distribution of sunlight. Why is an organism's niche like a person's occupation? An organism can "make a living" and survive in its niche. a natural phenomenon that maintains Earth's temperature range.
