Which explanation should the nurse consider as the most likely reason for the partner’s reaction?

Below are class results from an experiment using dialysis tubing (a semi-permeable membrane) filled with one solution and placed in another. The tubing was weighed over time. However, the instructor forgot which solutions were used by each group. The results for the five groups in the class: Group A, Group B, Group C, Group D, and Group E are graphed below. Help your instructor determine which group(s) placed their dialysis tubing in a HYPOTONIC solution.

If an atom of hydrogen has 1 proton, 1 neutron, and 1 electron, what is the mass number?

If an atom has 6 protons, 6 neutrons and 6 electrons, on the periodic table, we know this atom is carbon. Which of these subatomic particles allowed you to identify it as carbon?

Imagine researchers place a mouse and a plant inside a clear glass container, add a feeder bottle containing water, and add a container of grain that contains radiolabeled carbon (i.e., the sugars in the grain contain 14C instead of the regular 12C so that they can be tracked). They then water the plant with water containing the heavier isotope 18O instead of the regular 16O. They seal the container so that there are no inputs or outputs other than light. They then leave the system sealed for a week, during which time the mouse consumes grain and water from the water bottle, and the plant uses water from the soil containing the 18O. 1. Following consumption by the mouse, what happens to the 14C, and where does it go? 2. Following uptake by the plant, what happens to the 18O, and where does it go? Please label your answers 1. and 2. and explain both parts fully and clearly.

(OPTIONAL) Extra Credit (up to 2 points) Consider what you have learned in Unit 1: Cells, Structures, Diffusion, and Transport Please pick a single topic, e.g., a single learning objective from Unit 1 that was not already discussed in the essay questions above (i.e., do not re-discuss the essay questions you already answered). This might be something you found especially interesting, something you initially struggled with but then learned well, something you are especially confident of and perhaps wished was covered more thoroughly on this test, or anything else you want from this content. For this topic: Identify the topic Explain the topic and why it is important (be specific!) Write a single multiple choice question addressing this topic Your answer should be a paragraph of at least 4-5 sentences. Please do not just list out names of multiple topics. You may tell me you found this topic especially interesting, but you must demonstrate that you learned about and understand this topic by explaining it clearly. Note that there is not a single answer to this question, this is your chance to demonstrate good knowledge of any topic of your choosing from your work in this unit!
