PLEASE HELP!!Why might humans not have widespread regeneration abilities?

aev [14]

Answer:

Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?

Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= $\frac{600}{20}$ = 30
