Answer:
The answer is 'B'- There is already soil present.
Explanation:
One of the biggest difference between primary succession and secondary succession is that primary succession occurs where there is zero availability of soil. In case of secondary succession, an already established community gets hampered due to <em>man made</em> activities or natural disasters like <em>flood, rain</em>, etc.
Since there is soil present in his farmland and vegetation is also available, it is the process of secondary succession.
Answer:
Contusion
Explanation:
Contusion is as a result of bruises and it happens when an injured capillary or blood vessel leaks some amount of blood into the surrounding area. Contusions are a type of hematoma, which refers to any collection of blood and can be associated with multiple microhemorrhages, small blood vessel leaks into brain tissue. Contusion is common in 20–30 percent of severe head injuries.
The principle of competitive exclusion states that two species cannot coexist in the same habitat.
<h3>What is
competitive exclusion?</h3>
The competitive exclusion principle, often known as Gause's law, is a theory in ecology that holds that two species competing for the same scarce resource cannot coexist at constant population levels. One species will eventually outnumber all others if it has even a modest edge over the others. This results in the weaker competitor's extinction or an evolutionary or behavioral shift in favor of a different ecological niche. The adage "complete competitors cannot coexist" is a paraphrasing of this idea.
Although he never created it, Georgy Gause is traditionally credited with coming up with the competitive exclusion principle. The natural selection theory put forward by Charles Darwin already incorporates the concept.
The status of the principle has fluctuated during the course of its history between

Sickle cell disorder is an inherited blood disease featured by defective hemoglobin. The condition affects the hemoglobin, or the red blood cells, and their tendency to conduct oxygen. The normal hemoglobin cells are round, smooth, and flexible, and thus, they can travel via the vessels in the body effortlessly.
On the other hand, the sickle cell hemoglobin cells are sticky and stiff and form a sickle, C shape, when they lose their oxygen. These cells combine together, and cannot effortlessly move through the blood vessels.
