Answer:
Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.
Explanation:
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.
Answer:
I am pretty sure that the answer is iron.
Explanation:
I just took the quiz and grains were wrong, and when you diet you can eat a lot of dairy products and your supposed to drink lots of water. That is how I concluded that iron is the answer. Tell me if I got it right.
0.15 percent
BAC is the blood alcohol level in the body, and your body is able to eliminate about 0.15% of the blood alcohol present per hour. When a person consumes alcohol, 10% of the alcohol is lost from breath, sweat and urine. The remaining 90% is metabolized in the body.
