Answer:
In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.
Explanation:
Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.
The term "law" is a historical relic going back to Newtonian times, when after Newton's development of classical mechanics, it was thought that the workings of the universe were directly analagous to a perfectly constructed and perfectly predictable clockwork. That was turned on its head as a result of quantum mechanics, and modern scientists typically avoid use of the term "law" anymore because it is too dogmatic. Newton's "Laws" are still called that mainly for historical reasons now. What used to be called laws are now called theories.
<span>Proto-oncogenes are genes that normally help cells grow. When a proto-oncogenemutates (changes) or there are too many copies of it, it becomes a "bad" gene thatcan become permanently turned on or activated when it is not supposed to be. When this happens, the cell grows out of control, which can lead to cancer.....Is this what you need ?</span>
