D because many people don't see the depression and anxiety that comes with worrying about money as important as drug addiction or feelings of inadequacy
125 ml/hour x X hours = 1000 ml
X = 1000 ml/ 125 ml/hour
X = 8
It will take 8 hours
Answer: It is a noninfectious disease caused by environmental factors.
Explanation: Mercury is a type of toxic metal that comes in different forms within the environment. Therefore, it is not caused by bacteria, genetic factors, or pathogens. But from the environment.

Answer:
1. spontaneously
2. resting potential
3. action potentials
4. pacemaker potentials
5. K+
6. Na+
7. into
8. Ca+
Explanation:
Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+ and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
