Answer:
Buffers are the solution that is used to maintain the pH of the solution. It resists the change in the pH. Since, many of the chemical reactions are very specific to pH and temperature so it is very important to maintain the pH of the solution.
The bicarbonate ions and hydroxide ions serves as natural buffers in the blood. If the pH of the blood goes down below the normal then bicarbonate ions are released to maintain the pH of the blood.
If the p of the blood goes more than normal then the hydroxide ions acts as a buffer and maintains the pH of the blood.
Answer:
a. It is used to learn about the behavior of the universe.
b. It was used by Hubble to measure velocities of galaxies.
c. It indicates galaxy motion through light wavelengths.
Explanation:
Given what we know, we can confirm that the cell theory states that all cells come from preexisting cells despite the cells in a multicellular organism being so different from one another due to cellular differentiation.
<h3>What do we know about cellular differentiation?</h3>
- Cellular differentiation involves the selective expression of DNA.
- When only specific parts of the DNA sequence are expressed, and thus only specific proteins are formed, a cell can differentiate.
- This allows the cells to specialize themselves despite all of them containing the same DNA.
- Over time, this has allowed all cells, despite sharing a common origin, to become vastly different.
Therefore, given that cellular differentiation controls what genes of a cell are expressed in order to allow the cell to specialize itself into a specific cell type, this explains why even though all cells share a common origin, they can all be very distinct.
