Q: Answer the following question given this paragraph: Bones look tough, shiny, and white because they are covered by a layer called the periosteum . Many bones also contain a soft connective tissue called bone marrow in the pores of the spongy bone. Bone marrow is where blood cells are made. Q: What layer covers the bones that make them look tough, shiny, and white? Choices: - epithelium - cuticle - epidermis - periosteum A:
A: periosteum
Question: Answer the following question given this paragraph: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. Ecell = Ecathode Eanode +0.34 V = E 2+ EH + /H = E 2+ 0 = E Cu. Q: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at this? Choices: - Spinner - plasma - electrode - cathode A:
Answer: cathode

Answer the following question given this paragraph: A colloid is a homogeneous mixture with medium-sized particles. Examples include homogenized milk and gelatin. The particles of a colloid are large enough to reflect light, so you can see them. But they are too small to settle or filter out of the mixture. Q: A colloid is a homogeneous mixture with medium-sized what? Choices: - atoms - solutions - molecules - particles A:
**Answer**
particles
Q: Answer the following question given this paragraph: Plasma Anticoagulants An anticoagulant is any substance that opposes coagulation. Several circulating plasma anticoagulants play a role in limiting the coagulation process to the region of injury and restoring a normal, clot-free condition of blood. For instance, a cluster of proteins collectively referred to as the protein C system inactivates clotting factors involved in the intrinsic pathway. TFPI (tissue factor pathway inhibitor) inhibits the conversion of the inactive factor VII to the active form in the extrinsic pathway. Antithrombin inactivates factor X and opposes the conversion of prothrombin (factor II) to thrombin in the common pathway. And as noted earlier, basophils release heparin, a short-acting anticoagulant that also opposes prothrombin. Heparin is also found on the surfaces of cells lining the blood vessels. A pharmaceutical form of heparin is often administered therapeutically, for example, in surgical patients at risk for blood clots. Q: What do you call any substance that opposes coagulation? Choices: - dissolvent - antibodies - toxin - anticoagulant A:
A: anticoagulant
