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: OPTION B (ENCODING)
EXPLANATION: Encoding is a part of memory development which involves the acquisition of information into the brain.
Furthermore, this process is established through the collection of sensory information from the extrinsic environment, the brain receive, code and store the information for record and future retrieval purposes. This process usually involves automatic and effort-based processing.
Hence, Daniel is reading which is an effort-based processing to encodes the necessary information into his brain for future retrieval.
