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:
Diagnostic, formative, benchmark and summative are few assessments that are used to identify students' strength and weaknesses.
Explanation:
There are four examples that helps a teacher identify the strength and weakness of a student. In diagnostic assessment, the student is analyzed by reading assessments and how fluent he is. He is also tested by the way he can cope up with a comprehension. In formative assessment, the student is watched and see how far he can understand the subject and is made to write a test time to time. The teachers questions the students as well as check over how their speech is. Benchmark and summative assessment are quite alike. A student's growth is tested with the end exam. A student is tested to see how far his knowledge is developed throughout the year with the help of benchmark and summative assessments.
During anaerobic activity, your body is burning energy with a lack of oxygen, so it reaches into your glycogen stores and burns glucose. Anaerobic activities like strength training also build muscle, which helps your body burn more calories at rest. All of this, increasing the rate of your metabolism
