Fresh red meat, such as beef, has a red color because of the Fe2+ found in hemoglobin. When cells die, this iron oxidizes to Fe3+, giving the meat a brown color. Sometimes, grocers and butchers suffuse meat with carbon monoxide to make it appear fresher because when CO binds to the heme in hemoglobin, it gives the meat a red color.
A particular genomic caretaker protein, Protein X, has an affinity for both Ligand Y and Ligand Z. When you have 0.23 microM of Protein X in a solution and mix it with 0.11 microM of Ligand Y, the resulting solution contains 0.20 microM of free Protein X, 0.09 microM of free Ligand Y, and 0.02 microM of the protein-ligand complex, after equilibrium has been reached. However, when you have 0.23 microM of Protein X in a solution and mix it with 0.11 microM of Ligand Z, the resulting solution contains 0.14 microM of free Protein X, 0.02 microM of free Ligand Z, and 0.09 microM of the protein-ligand complex, after equilibrium has been reached. Which ligand has a greater affinity for Protein X?
a. Ligand Y
b. Ligands Y and Z have equal affinity for Protein X.
c. Ligand Z
d. It is not possible to determine with the given information.

(04.05 hc) analyze the given diagram of the carbon cycle below. an image of carbon cycle is shown. the sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. an arrow is shown from the sun towards the left tree marked a. the sun is marked b. there is an arrow from the air above the clouds, marked c, towards the left tree. an arrow from a location close to the ground marked d points towards dead organisms, which is a label under the animal. an arrow marked e points from the right tree straight up to the clouds. an arrow marked f points from the animal straight up to the clouds. an arrow marked g points from the factory towards the air above the clouds, c. there is an arrow pointing from the air to the lake labeled carbonates in water, an arrow pointing down from dead organisms to fossils and fossil fuels, and an arrow from fossils to the factory. part 1: which compound does c represent? part 2: name a process that could release this compound into the air. part 3: explain how the elements that form it are conserved during the carbon cycle. use complete sentences to explain your answer.
