Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

Answer:
20%
Explanation:
Given that:
Actual weight of 1 mL of water =. 1g
Average weight using :
TOOL A = 1.2
TOOL B = 1.5
Percentage Error of TOOL A:
(|approximate measurement - actual measurement| / actual measurement) * 100%
(|1.2 - 1| / 1) * 100%
(0.2 / 1) * 100%
0.2 * 100%
= 20%
