<span>The correct answer is b. Option a is incorrect because these models can demonstrate scientific theories, but they don't prove scientific theories (you would need experiments for that). Option c is incorrect because the models aren't always representing something abstract (i.e. DNA is very real, just very small). Option d is incorrect because they don't precisely mimic something in nature, but instead help us visualize something in nature that is difficult to see or comprehend.</span>
The Electromagnetic spectrum<span> lists the most powerful EMR, </span>gamma<span> rays, to the least powerful EMR, radio waves. In addition, the highest energy waves (</span>gamma<span>, x-ray) have the shortest wavelengths. The lowest energy waves, radio waves, have longest wavelengths.</span>
Explore a wide variety of cells, from bacteria to human neurons, using a compound light microscope. Select a sample to study, then focus on the sample using the coarse and fine focus controls of the microscope. Compare the structures found in different cells, then perform tests to see if the sample is alive.
Typhitis, also called neutropenic enterocolitis, is an infection that often develops in cancer patients who undergo chemotherapy. In many cases, surgical intervention is required.
Without surgical intervention, the patient would be transferred to an ICU (Intensive Care Unit) for monitoring, and the nurse would perform some or all of these emergency actions:
1. Bowel rest and nasogastric suction,
2. Serial abdominal examinations,
3. Providing intravenous fluids, blood, and platelet transfusions when needed,
4. Using antibiotics to fight the infection, and obtaining cultures to determine if the antibiotic is working,
5. Not administering medication that could worsen the situation.
A mammals need for oxygen effects their heart rate because there could be some cases where they're in lack of oxygen causing them to be literally ' out of breath ' . Like climbing a mountain. The higher you go the less oxygen.
