Answer:
True
Explanation:
When you combine flour with liquid and stir or knead, the proteins in the flour form gluten. The gluten in the flour develops and becomes strong and elastic, forming a network of tiny air cells.
He must find his average heart rate zone
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.

in multicellular is a form of asexual reproduction
or cloning in which an organism is split into fragments. Each of these
fragments mature into fully grown individuals that are clones
