E. neutrons and protons in the atom mass number of an atom is the number of II. Which of the following is mismatched? A, splastie anemia - bone marrow fails to produce erythrocytes B. hemolytic anemia- increased destruction of erythrocytes C pernicious anemia- loss of blood from the body D. iron deficiency anemia- lack of iron absorption for erythropoiesis E hemorrhagic anemia- loss of blood from the body 12. Consider the following structural levels: chemical, organ, tissue, cell, and encompasses the other four? A. tissue B. organ system C. organ D. chemical E. cell organ system. Which level 13. A red blood cell that is placed in a hypertonic solution A. gains water B. loses water. C. floats D. ruptures. E. neither gains nor loses water. 14. What type of connective tissue is found between the vertebrae? A. hyaline cartilage B. fibrocartilage C. elastic cartilage D. dense irregular elastic tissue E. dense regular collagenous tissueExplanation / Answer
10) A mass number of an atom is the total number of protons and neutrons in the atoms.
11) The mismatch is pernicious anemia and loss of blood from the body.
The right match or correct match to this - is pernicious anemia and Vitamin B12 deficiency. Pernicious anemia is a condition due to lack of intrinsic factor in the stomach leading to impaired uptake of Vitamine B12. Intrinsic factor absorbs Vit B12.
12) Organ system encompasses the other 4. Organ system has organs which have tissues which constitute cells which produce chemicals.
13)Hypertonic solution is a solution with more salt. When red blood cells are placed in hypertonic solution, the water moves out from the red blood cells to the surrounding solution by osmosis. This causes the RBC to shrink.
14) Fibrocartilage is connective tissue found between the vertebrae. Fibrocartilage is a mix of dense regular connective tissue and hyaline cartilage. It resists tension. It is found where strong support and ability to withstand heavy pressure is needed. It is found in between vertebrae- intervertebral discs and knee meniscus.
