NAS2 Challenge Exam Questions with 100% Correct Answers | Verified | Updated 2023-2024 Purpose of Scientific Method - Correct Answer-solve a problem or answer a question Question, Hypothesis, Experiment, Observe & Record, Analyze, Conclude - Correct Answer-steps of scientific method Independent variable - Correct Answer-a variable that stands alone and isn't changed by the other variables you are trying to measure, change or controlled example: age dependent variable - Correct Answer-a variable dependent on other factors, tested or measured example: test score - factors that go into a score you receive on a test control group - Correct Answer-does not receive treatment and used to compare or measure the other subjects experimental group - Correct Answer-exposed to changes in independent variable anatomy - Correct Answer-branch of science concerned with bodily structure of living organisms; structure physiology - Correct Answer-science dealing with the functions of living things or their organs level of organization - Correct Answer-living things arranged from the simplest to most complex are: organelle cells tissues organs organ systems, organism populations communities ecosystem biosphere requirements for life - Correct Answer-Cellular organization Reproduction Metabolism Homeostasis Heredity Response to stimuli Growth and development Adaptation through evolution survival needs - Correct Answer-Food, oxygen, water, body temperature, atmospheric pressure (oxygen/carbon dioxide exchange) homeostasis - Correct Answer-relatively constant internal physical and chemical conditions that organisms maintain receptor - Correct Answer-senses environmental stimulus and sends info to control center control center - Correct Answer-hypothalamus signals effector effector - Correct Answer-responds to stimuli example: muscle contracting negative feedback mechanisms - Correct Answer-net effect is that the original output of the system shuts off the original stimulus or reduces the intensity homeostasis negative feedback mechanisms - Correct Answer-most common form of homeostasis, bringing people back to normal functioning negative feedback mechanisms - Correct Answer-example of homeostasis: adjustments of blood pressure, metabolism, body temp positive feedback mechanisms - Correct Answer-form of homeostasis level of variable changes in same direction as initial change enhances or accelerates output created by activated stimulus positive feedback mechanisms - Correct Answer-example of type of homeostasis: platelet aggregation or accumulation in response to injury, child birth anatomical position - Correct Answer-erect position, face forward, arms at side, palms face forward used to describe relation to other things coronal, sagittal, transverse - Correct Answer-3 major planes of dissection PH - Correct Answer-measure of acidity measure of hydrogen ion concentration basic/alkaline - Correct Answer-if pH is above 7 it is... acidic - Correct Answer-if pH is below 7 its... diffusion - Correct Answer-Movement of a substance from an area of high concentration to an area of low concentration dialysis - Correct Answer-small molecules can diffuse through semipermeable membranes osmosis - Correct Answer-net movement of water through semipermeable membrane organic compound - Correct Answer-any member of large class of gaseous, liquid, or solid chemical compounds, must contain hydrogen monomer - Correct Answer-small unit that can join together with other small units to form polymers polymer - Correct Answer-large compound formed from combinations of many monomers carbohydrates - Correct Answer-glucose, glycogen, monosaccharides, polysaccharides lipids - Correct Answer-fatty acids, alcohols, monoglycerides, diglycerides, steroids, terpenes, carotenoids proteins - Correct Answer-insulin, histone, hemoglobin macromolecules that contain nitrogen as well as carbon, hydrogen, and oxygen nucelic acid - Correct Answer-RNA, DNA function - Correct Answer-_____ of a protein is dependent on its 3D structure determined by a sequence of amino acids in the protein polymer proteins - Correct Answer-embodiment of the transition from one-dimensional to three cell theory - Correct Answer-All life is made up cells which are the basic units of life and come from preexisting cells requirements of cell life - Correct Answer- ribosomes - Correct Answer-makes proteins golgi apparatus - Correct Answer-make, process, and package proteins lysosome - Correct Answer-contains digestive enzymes to help break down food endoplasmic reticulum - Correct Answer-"intracellular highway" transports item around the cell, creates lipids of fat mitochondria - Correct Answer-Powerhouse of the cell, organelle that is the site of ATP (energy) production nucleus - Correct Answer-brains of the cell, directs cell activity and contains genetic material called chromosomes made of DNA cytoplasm - Correct Answer-jellylike substance inside cells that contains molecules and in some cell organelles Translation and glycolysis takes place cisternae - Correct Answer-flattened stacked membrane folds liposome - Correct Answer-membrane bound transport vescicles chloroplast - Correct Answer-creates glucose photosynthesis G0 - Correct Answer-not growing or dividing G1 - Correct Answer-cell growth, cellular contents (not chromosomes) duplicated S - Correct Answer-each of the 46 chromosomes duplicated by cell DNA synthesis (replication) G2 - Correct Answer-"double checks" the duplicated chromosomes for error and makes repairs cell growth (interphase, 46 chromosomes) mitosis - Correct Answer-a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth prophase - Correct Answer-chromosomes doubled condensation of chromatin, nucleolus disappears metaphase - Correct Answer-second most condensed and coiled phase, chromosomes align in the equator of the cell before being separated into daughter cells anaphase - Correct Answer-most condensed and coiled, chromatids split and move to opposite poles of the cell separated chromosomes pulled apart telophase - Correct Answer-microtubules disappear all division begins two nuclei are formed at opposite ends cytokinesis - Correct Answer-separation of cell components, two daughter cells formed each with 46 chromosomes most condensed and coiled, chromatids split and move to opposite poles of the cell anterior - Correct Answer-at or near the front of the body posterior - Correct Answer-at or near the back of the body midline - Correct Answer-an imaginary vertical line that divides the body equally lateral - Correct Answer-farther from midline side view medial - Correct Answer-nearer to midline side view superior - Correct Answer-toward the head/upper part of a structure looking down inferior - Correct Answer-away from head or lower part of a structure looking up superficial - Correct Answer-close to the surface of the body deep - Correct Answer-away from surface of the body proximal - Correct Answer-nearer to the origination of a structure distal - Correct Answer-farther from the origination of a structure coronal plane - Correct Answer-frontal plane A vertical plane running from side to side; divides the body or any of its parts into anterior and posterior portions. sagittal plane - Correct Answer-lateral plane A vertical plane running from front to back; divides the body or any of its parts into right and left sides
