On the Galápagos Islands, the finches that Darwin studied tended to have either small beaks or large beaks. The smaller beaks ar
e best at eating soft seeds but are ineffective at cracking large seeds. The larger beaks are best at cracking hard seeds. Beaks of intermediate size are inefficient for either seed type. Which result of natural selection is at work in this example? A. stabilizing selectionB. directional selectionC. disruptive selectionD. individual selectionE. unnatural selection
The correct answer is option C. "disruptive selection".
Explanation:
Disruptive selection is a type of natural selection at which extreme values for a trait are favored, while intermediate traits are more likely to disappear. In this example the finches tended to have either small beaks or large beaks because small beaks are best at eating soft seeds and large beaks are best at cracking seeds. This is an example of disruptive selection because the two extreme values for the size of beaks are favored.
The corpus callosum associates the left half of the cerebrum to the correct side, each side being known as a side of the equator. The association permits data to go between the two parts.
Corpus callosum is Latin for "extreme body," and the corpus callosum is the biggest connective pathway in the mind, being comprised of in excess of 200 million nerve strands.
Occasionally, an individual will be conceived without a corpus callosum. This is known as agenesis of the corpus callosum, and it causes a wide assortment of physical and social indications.
Each side of the mind controls development and feeling in the contrary portion of the body. The halves of the globe additionally process data, for example, language.
In this manner, physical coordination and taking in complex data requires the two sides of the cerebrum to cooperate.
