<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>
Answer:
The corpus callosum
Explanation:
The corpus callosum is the largest white matter structure in the brain. It is located beneath the cerebral cortex and it connects the left and right cerebral hemispheres thus enabling communication between them. The corpus callosum is a bundle of nerve fibers, (axon projections) which transmits neural signals.
Data collected by the drilling ship Glomar Challenger confirmed that C. NONE OF THE OCEAN FLOOR IS MORE THAN 180 MILLION YEARS OLD.
Glomar Challenger began drilling on both sides of the mid-ocean ridges to gather data. The data confirmed what the sea-floor spreading hypothesis predicted. The ocean floor is youngest along the central valley of the mid-ocean ridge while the ocean floor in subduction zones or near the edges of the continents is oldest. The data has confirmed that none of the ocean floor is more than 180 million years old because the older oceanic rock will undergo subduction and go back to the earht's mantle.

The forest would be cooler because the trees are thick and no sunlight is allowed through. things are much cooler when there’s no sunlight allowed near them- think about the difference on a hot summers day sitting in unshaded grass vs sitting in shady grass under a big tree.
