the birds either starve or adapt to their new circumstances
Answer:
The correct answer is c. cell fractionation
Explanation:
Cell fractionation is the technique which allows different cells part to be separated from each other on the basis of their density gradient by using a centrifuge.
In cell fractionation, first the cell wall and membrane of cells are broken by chemical, physical or mechanical method. Then the cell component can be separated by centrifuging them at different rpm.
Components that have higher density can be found in the bottom and the light density can be found on top of the tube. Therefore the correct answer is c. cell fractionation.
Chemical and light. light would be for most
Answer:
A
Explanation:
Adaptations that can be seen with the naked eye are structural adaptations.
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poorblood from the body into the right atrium of the heart.i As the ventricle contracts, blood leaves the heartthrough the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated
How does blood flow through the heart step by step?
Blood from the body flows:
1. to the superior and inferior vena cava,
2. then to the right atrium.
3. through the tricuspid valve.
4. to the right ventricle.
5. through the pulmonic valve.
6. to the pulmonary artery.
7. to the lungs
