5: true
6: Oxygen
7: H+
8: true
Answer:
Question 7:
C
Question 8:
C
Explanation:
Question 7:
If the pH number is smaller, the solution is more acidic. In turn, this means that it contains more H+ ions that OH- ions
Question 8:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution
Answer:
- Microevolution happens at a <u>smaller</u> scale, hence the prefix micro.
- Macroevolution happens at a <u>larger</u> scale, hence the prefix macro.
- Microevolution occurs within a single population or species, over a shorter period of time.
- Macroevolution can occur among multiple species, and takes a longer period of time.
