Answer the following question given this paragraph: The blood protein hemoglobin binds with oxygen and carries it from the lungs to cells throughout the body. Heme is a small molecule containing iron that is part of the larger hemoglobin molecule. Oxygen binds to the iron in heme. Q: What blood protein carries oxygen from the lungs to cells throughout the body? Choices: - plasma - platelets - dopamine - hemoglobin A:
hemoglobin

Answer the following question given this paragraph: Lymphocytes: B Cells, T Cells, Plasma Cells, and Natural Killer Cells As stated above, lymphocytes are the primary cells of adaptive immune responses (Table 21.1). The two basic types of lymphocytes, B cells and T cells, are identical morphologically with a large central nucleus surrounded by a thin layer of cytoplasm. They are distinguished from each other by their surface protein markers as well as by the molecules they secrete. While B cells mature in red bone marrow and T cells mature in the thymus, they both initially develop from bone marrow. T cells migrate from bone marrow to the thymus gland where they further mature. B cells and T cells are found in many parts of the body, circulating in the bloodstream and lymph, and residing in secondary lymphoid organs, including the spleen and lymph nodes, which will be described later in this section. The human body contains approximately 10 12 lymphocytes. Q: What are the primary cells of adaptive immune response? Choices: - erythrocytes - red blood cells - white blood cells - lymphocytes A:
(Answer)
lymphocytes
Ques: Answer the following question given this paragraph: The amount of power passed through transmission lines can be calculated by multiplying voltage by current. The same power can be transmitted using a very high voltage and a very low current as with a low voltage and high current. Q: The amount of power passed through transmission lines can be calculated by multiplying voltage by what? Choices: - resistance - amplification - induction - current A:
Ans: current
(Q).

A small scale map displays individual rock units while a large scale map shows geologic provinces. Q: A small scale version of what type of map displays individual rock units? Choices: - seismic map - geographic map - polar map - geologic map A:
(A).
geologic map
Ques:Answer the following question given this paragraph: Q: The same reaction regenerates pyruvate, which is transported to which cells? Choices: - outermost - skin - symbionts - mesophyll A:

Ans:mesophyll
Answer the following question given this paragraph: 13 Photosynthesis 6 CO2 + 6 H2 O C6 H12 O6 + 6 O2 One of most important reactions in history of life: source of atmospheric O2 ultimately led to aerobic respiration and eukaryotes Responsible for bulk of glucose production Early experiments showed that mass of plant must be derived from substances in the air, not the soil Experiments with isotopes showed that liberated oxygen comes from water Experiments also showed that light is essential but that some reactions (e. , reduction of CO2 ) continue in the dark Plants do two big, important things during photosynthesis: gain energy (absorb light) and build sugar (glucose). Photosynthesis can be divided into two series of chemical reactions: the light (lightdependent) reactions and the dark (light-independent) reactions. In light reactions, light is absorbed; in dark reactions, sugar is built. Occurs when plants, algae, and autotrophic bacteria absorb light energy and build glucose. Q: What is the process by which plants gain energy and produce sugar? Choices: - glycolysis - respiration - chemosynthesis - photosynthesis A:
photosynthesis
