Prokaryotic cells are cells that can function independently. They consist of everything needed for that cell to nourish itself and to grow and reproduce.
Answer:
Modern theory of evolution explains that "organisms change over time as a result of changes in heritable physical or behavioral traits". Hence this change suggests the loss of vestigial organs.
Explanation:
- Vestigial organ are those which do not have any function but is present in our body.
- According to the modern theory the genetic and physical appearance changes along with the adaptation in environment by the organism.
- So if the organ looses its function in order to sustain and adopt in the changing environment then they become vestigial and slowly disappear.
- This is the common example for the Lamarck's theory of "use and disuse".
2) The concentration of O2 will increase inside the cell.
The cell will want to reach equilibrium, meaning that there should be an equal number of oxygen inside and outside the cell. In the picture, more oxygen is shown outside the cell than inside so oxygen will flow into the cell until it has reached equilibrium. Therefore, the concentration of O2 will increase in the cell.
