(2021/2022 Revised Exam Practice Guide) Set 1_ Anatomy and Physiology • Fluid balance might be negatively impacted when the fail. • Kidneys • Ears • Nose • Legs A Kidneys are responsible for regulating fluid balance. • The stage of mitosis in which the chromatin condenses and becomes a chromosome is • Prophase • Metaphase • Anaphase • Telophase A Prophase, is a stage of mitosis in which the chromatin condenses (it becomes shorter and fatter) into a highly ordered structure called a chromosome in which the chromatin becomes visible • The stage of mitosis in which the chromosomes begin to align is . • Prophase • Metaphase • Anaphase • Telophase B Metaphase is a stage of mitosis in the eukaryotic cell cycle in which condensed& highly coiled chromosomes, carrying genetic information, align in the middle of the cell before being separated into each of the two daughter cells. Preceded by events in prometaphase and followed by anaphase, microtubules formed in prophase have already found and attached themselves to kinetochores in metaphase • The stage of mitosis in which the paired chromosomes separate, each going to an opposite pole of the cell, is. • Metaphase • Prophase • Anaphase • Anaphase D Anaphase, from the ancient Greek ἀνά (up) and φάσις (stage), is the stage of mitosis or meiosis when chromosomes move to opposite poles of the cell. Anaphase begins with the regulated triggering of the metaphase- to-anaphase transition. Metaphase ends with the destruction of cyclin, which is required for the function of metaphase cyclin-dependent kinases (M-Cdks). Anaphase is initiated with the cleavage of securing, a protein that inhibits the protease known as separase. Separase then cleaves cohes in, a protein responsible for holding sister chromatids together. • The stage of mitosis in which the two chromosomes are cordoned into new nuclei within the daughter cells is . • Metaphase • Prophase • Anaphase • Telophase D Telophase is a stage in both meiosis and mitosis in a eukaryotic cell. During telophase, the effects of prophase and prometaphase events are reversed. Two daughter nuclei form in the cell. The nuclear envelopes of the daughter cells are formed from the fragments of the nuclear envelope of the parent cell. As the nuclear envelope forms around each pair of chromatids, the nucleoli reappear. • The smallest unit of life in our bodies is the • Atom • Molecule • Proton • Cell D The smallest unit of life in our bodies is the cell. • One of the functions of the cell membrane is to • Divide into other cells. • Control what moves into and out of the cell. • Fight infection. • Trap bacteria. B The cell membrane or plasma membrane is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ion sand organic molecules and controls the movement of substances in and out of cells
