This exchange process takes place in the aveolus (air sac) inside your lungs by diffusion.
it's from a different concentration gradient
the deoxygenated blood with carbon dioxide diffuse into a aveoli (which is in high concentration) and the aveoli release the oxygen into the blood stream (which is low concentration) therefore the blood will be oxygenated again
Answer:
The following scientists have performed different experiments that were helpful in providing evidence that DNA is the genetic material. The summarize experiments are as follows-
1. Fredrick Griffith- the experiment was an experiment performed in 1928. It was one of the experiments that exhibit that bacteria can acquire through the process of transformation.
2 Oswald Avery, Maclyn McCarty, and Colin MacLeod: this experiment exhibited that DNA can transform the cell properties, and clarifying the chemical properties of the genes.
3. Alfred Hershey and Martha Chase: They determined that even the bacteriophage has a protective coat around it but the DNA that is present inside is the genetic material that has the ability to produce the progeny inside a bacterium.
4. Erwin Chargaff: He proposed tow rules which were named after him as chargaff rules. This tells that natural DNA the number of cytosines is equal to the number of guanine units and adenine to Thymine units.
Answer:
The earth can be said to be a system because each component inside it interacts so that it creates a very large number of collectivities. Components in the earth are incorporated into a Geosphere, namely a layer on the surface or under the surface of the earth that has a direct and indirect influence on the survival of creatures
