ATI TEAS 6 SCIENCE (ATI TEAS 6)

Science Cell Cell: basic organizational unit of all living things. One thing in common is they all have membranes (phospholipids). Cell structure organization: All cells contain DNA, and RNA & can synthesize proteins. Consists of nucleic acids, cytoplasm, and cell membrane. o Tissues: Cells that are grouped together o Organs: Tissues that are grouped together o Systems: Organs that are grouped together o Organism: A complete individual Nuclear parts of a cell o Nucleus: contains chro...

Cell Cycle · Mitosis = “daughter cell” exact replica · Interphase (G1, S, G2) · Prophase · Metaphase · Anaphase · Telophase · Cytokinesis · Meiosis = “daughter cells” different genetic coding · Only happens in gametes* · 1 st 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 diffe...

ATI TEAS 6 - Science (Human Anatomy and Physiology) Hierarchy of Structures Lowest Hierarchy level is at Organelles within a cell. They obtain energy from food and reproduction. -Cells with the same function are collected into larger groups called Tissues. -Tissues are collected into Organs, carry out single task, like oxygenated blood (lungs), or filter out waste (kidneys). -Organs work together in systems that perform coordinated large-scale functions, like nourishing the body (dig...
