A constructor must have a return type.

Imagine that the Calvin cycle of photosynthesis and the Krebs cycle of cellular respiration were merged into a single metabolic pathway inside one organelle (we’ll call it the “metaboplast”). In this system, the stroma and matrix are fused into one compartment, and the enzymes of both cycles share the same pool of substrates. Design a theoretical model of how this “metaboplast” could function.  In your response, consider: 1) How carbon atoms would move through the combined cycle, and whether intermediates like RuBP and oxaloacetate could coexist or compete. 2) How ATP and NADPH/NADH requirements would be balanced, and whether one cycle could drive the other. 3) How reducing power (NADPH vs. NADH vs. FADH₂) would be allocated, and whether electron transport chains would need to be modified. 4) How membranes and compartments would need to be arranged to prevent conflicting gradients or futile cycles. 5) Evaluate whether such a hybrid organelle could theoretically sustain both anabolic (glucose synthesis) and catabolic (glucose breakdown) processes without self-canceling.

Imagine you are playing the role of one molecule of ATP. Starting at the very beginning, evaulate and describe the path that this ATP would need to pass through in order to move from where it is produced in a chloroplast into the cytoplasm of the cell. (Be sure to include specific membranes and other structures as you complete the path). 

An altruistic act is one that costs the altruist something but provides a benefit to another individual. Suppose that Chirpy, Digger, Scout, and Zippy are individuals in an altruistic species of mammal. The altruistic act they perform is to share food with others. Consider the following interactions: Zippy has never interacted with Chirpy and is requesting food for the first time. Digger is requesting food from Chirpy; Digger has previously given food to Chirpy. Scout is requesting food from Chirpy; Scout previously refused to share food with Chirpy. Under reciprocal altruism, we would expect Chirpy to share food with ________.

In a very deep temperate lake, turnover happens every spring and fall. As a result of climate change, turnover is decreasing. What impact would this be predicted to have on net primary productivity (NPP) in the lake?

A student becomes interested in studying the voles (a small mammal, pictured below) that live near their house. The student suspects that they are following optimal foraging theory based on observations they have made of the voles. Which of the following observations are consistent with optimal foraging theory? Choose all correct.

Early successional species _____________.

The nurse is caring for a client with a platelet count of 42,000/mm³ who is being treated for immune thrombocytopenic purpura (ITP). Which nursing intervention should the nurse implement to ensure client safety?

The nurse is caring for a client with Stage 4 Chronic Kidney Disease (CKD) whose hemoglobin has decreased to 9.2 g/dL. When explaining the pathophysiology of this anemia to the client, which statement by the nurse is most accurate?
