The type of method of neuroimaging that the doctor should
use in detecting a possible tumor that he thinks Samantha has is the MRI or
also known as the Magnetic Resonance Imaging. This is scan that will help in
recognizing a tumor in a person’s body.
1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.
2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.
3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches
4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.
I tried my best hope this helps :)
The answer is; C
A PET scan is a positron emission tomography used to image the inside of the body. It involves the ingestion of a radioactive element. The element is actively absorbed by the tissue with active cellular activity hence these areas will show as bright spots when the body (this case the brain) is scanned.
Pores called stomata enable plants to exchange oxygen and carbon dioxide. If it weren't for these pores, the plants wouldn't be able to perform such an action.
