Summary TEAS Test Study Guide: Science

TEAS Test Study Guide: Science · Mitosis = “daughter cell” exact replica · Interphase (G1, S, G2) · Prophase · Metaphase · Anaphase · Telophase · Cytokinesis Cell Cycle · Meiosis = “daughter cells” different genetic coding · Only happens in gametes* · 1st phase · chromosomes cross over · genetic material exchanged · tetrads of 4 chromatids formed à Homologous pairs of chromatids are separated and go to different poles à2 cells go through 2nd cell division à 4 daughter cells with different sets of chromosomes · Haploid : contains half genetic material of parent cell · Zygote- controls cell differentiation Tissues à groups of cells à Muscle, nerve, epithelial, connective 2. Epithelial: (joined together tightly) ex. Skin 3. Connective: (dense, loose, or fatty) ex. Bone tissue, cartilage, tendons, ligaments, fat, blood, lymph àProtects & binds body parts a. Cartilage: cushions & provides structural support i. Fibrous b. Blood: transports oxygen to cells & removes waste / ALSO carries hormones & defends against disease c. Bone: (hard) produces red blood cells 2. Muscle: Support & move body a. Smooth b. Cardiac c. Skeletal 3. Nervous: ex. Brain, spinal cord, & nerves a. Neurons- control responses to changes in environment Organs à groups of tissues
