Study Notes
TEAS 7 Science Study Notes
- Central Nervous System Chemical Regulator: The hypothalamus releases chemicals to regulate the pituitary gland.
- Skeletal Muscle Sarcomere Shortening: Myosin and actin interaction shortens the sarcomere.
- Inherited Cell Mutations: Mutations in ovarian cells can be inherited.
- Tendons Function: Tendons connect skeletal muscles to bones.
- Urea Excretion: Urea is excreted by sweat glands in response to protein breakdown and ammonia formation.
- Metabolic Waste Removal: Excretion is the removal of metabolic waste from the body.
- Hypertonic Solution Osmosis: A cell in a hypertonic solution will lose water, resulting in a net flow of water out of the cell.
- Active Transport Example: The provided text does not list an example of active transport.
- Kidney Urine Concentration: Aquaporins in kidney cells help concentrate urine.
- Blood Vessel for Upper Body to Heart: The superior vena cava carries blood from the upper body to the right atrium of the heart.
- Carbohydrate Composition: Carbohydrates are composed of monosaccharides.
- Carbonic Acid-Bicarbonate Buffer System: In the blood, CO2 + H2O forms H2CO3, which converts to HCO3⁻ and H⁺. Excess H⁺ ions cause a shift in the equilibrium towards CO2 and H2O.
- Wavelength and Photosynthesis (Plant Experiment): The wavelength of light could affect plant growth.
- Correlational Study Weakness: Correlational studies cannot determine causation.
- Vasectomy Infertility: A vasectomy blocks sperm transport from the testes to the epididymis preventing fertilization.
- Lifelong Viral Immunity: Lifelong protection against viruses like chicken pox is from active immunity.
- Equal Mass Volume: An equal mass of a gas would completely fill either a 100 ml or 500 ml container
- Isotope C-12 Composition: C-12 has 6 protons and 6 neutrons in its nucleus.
- Paralysis Cause: Permanent damage to nervous tissue in the spinal cord can cause paralysis.
- COVID-19 Vaccine Initiation (Graph Needed): The provided text references a graph that's not included, making it impossible to determine data-supported statements about vaccine initiation.
- Mammalian Neuron Threshold: The threshold value for mammalian neurons is -55 mV.
- Plant Flower Phenotype Ratio: In a cross between a heterozygous red flower plant and a white flower plant, the expected phenotype ratio is 3 red: 1 white.
- Eukaryotic and Prokaryotic Cell Structure: Cell membranes are found in both.
- Tsunami Cause: Flooding could contribute to a tsunami.
- DNA Determination Method: Genes are used to determine a person's DNA sequence.
- Organic Molecules with Amine/Carboxyl Groups: Proteins contain both amine and carboxyl groups.
- Osteoporosis Cause: A decline in osteoblast activity while osteoblast activity continues at expected levels can lead to osteoporosis.
- Immune Cell Activation: Granzymes are released by cytotoxic T cells to directly activate other immune cells.
- Cell Measurement: Diameter is the measurement indicated by a line across the cell's center.
- Water Solvent Property: Water's polarity makes it a good solvent for other polar substances.
- Photosynthesis Wavelength Experiment (Plant Results): The plant response to different wavelengths of light suggests that infra-red light might have negative effects, while ultraviolet light has an adverse impact on plant growth.
- Immune Protection Type: Active immunity provides lifelong protection against viruses like chicken pox.
- Active Transport Definition: Active transport moves substances against a concentration gradient, requiring energy.
- Body Cavity Subdivision: The ventral cavity is subdivided into thoracic and abdominopelvic cavities.
- Layer Containing Glands and Hair Follicles: The dermis layer of skin contains glands and hair follicles.
- Atomic Number Example: Lithium (Li) has an atomic number of 3 and a mass number of 7. Its protons number 3.
- Cartilage Flap Preventing Food Entry: The epiglottis is the flap that prevents food from entering the trachea.
- Organelle Found in Both Cell Types: Endoplasmic reticulum is found in both prokaryotic and eukaryotic cells.
- AIDS Virus DNA Insertion: Reverse transcriptase, an enzyme carried by the virus, is responsible for inserting virus RNA into the host cell's DNA.
- Urine Output Percentage Change: A 50% increase in urine output from 800 mL/hr to 1200 mL/hr.
- Adaptive Immunity Explanation: The body can initiate internal defenses like phagocytes and natural killer cells or respond to specific pathogens to fight off infection.
- Water Curving Meniscus: Cohesive forces between water molecules overcome the adhesive forces between water and glass, leading to a concave meniscus.
- Bicarbonate Buffer System Reaction: When levels of H+ (Hydrogen ions) are excessive, the bicarbonate buffer system within the blood shifts to maintain balance between CO2, H2O, H2CO3, and HCO3-.
- Plant Photosynthesis Experiment: Wavelengths of light may influence plant photosynthesis in varying degrees, however the plant response to specific amounts of certain wavelengths was not provided in enough detail to determine conclusions.
- Hypothesis Definition: A hypothesis is a prediction about an observation in an experiment.
- Scientific Findings Validation: When new scientific findings are published, other scientists can verify these findings by testing them, as well as identify potential biases or limitations in the original research.
Additional Biological Concepts (from questions, but not a specific topic)
- Pyloric Sphincter: A muscle that helps regulate the transfer of food from the stomach.
- Proteases: Enzymes that break down proteins.
- Digestive Enzymes: Pancreatic enzymes like amylase, trypsin, and lipase have specific roles in digesting food.
- Immune System Components: Various immune cells like T-cells, B-cells, and macrophages play roles in fighting infection.
- Hormonal Regulation: Hormones like antidiuretic hormone regulate bodily functions.
- Oxygenated Blood Vessels: Pulmonary veins carry oxygenated blood from the lungs to the heart.
- Cardiovascular System Pathways: Blood circulation paths through the heart, lungs, arteries, and veins.
