Chromosomes, Mitoses, and Meiosis

Mito, Chloro, and Peroxi (ELE_BC Unit 3)

Unit 1 Study Guide Review 1. Anatomy = study the structures (ex: names/locations of bones) Physiology = study the functions (ex: how bones heal) Both are needed to understand the body 2. Homeostasis = maintaining stable body  conditions; controlled using feedback systems 3. During exercise = heart rate increased After exercise = heart rate decreased Negative feedback was used to return the  heart back to its normal resting rate 4. Chemical = oxygen Cell = muscle cell Tissue = muscle tissue Organ = stomach Organ system = digestive system Organism = human 5. Frontal = divides body into front and back  Transverse = divides body into top and bottom  Midsagittal = divides body into left and right 6. Responsiveness = waking up to an alarm,  feeling hungry after smelling food Differentiation = cells are assigned a specific function Growth = children's bones increase in  length/size as they age Reproduction = having a bebé Movement = picking up a cup to take a drink Metabolism =digesting food to obtain  energy 7. The elbow is proximal to the wrist The toes are distal to the ankle The heart is medial to the lungs The ears are lateral to the nose The stomach is superior to the bladder The heart is inferior to the brain The muscle is superficial to the bones The muscle is deep to the skin The eyes are anterior to the brain The spine is posterior to the collarbone 8. Receptor =picks up info about the body  (ex: blood pressure) Control Center = decides if action is needed  (ex: lower blood pressure) Effector = takes action (ex: increases width of blood vessels to lessen  pressure) 9. Front = frontal,anterior, ventral Back = posterior, dorsal 10. Negative Feedback = reverses a change in the body; most commonly used; ex: lowering blood sugar back to normal after a meal Positive feedback = increases a change in the  body; used for emergency/special situations; ex: increasing the frequency and strength of contractions during childbirth 11.  Face upright, palms forward (supine), weight even on both feet, arms slightly away from body 12. Cephalic (head), Cervical (neck), upper limb (arm), trunk (torso), lower limb (leg) 13. Sweat (will cool the body) 14. Shiver (will warm the body) 15. More oxygen and nutrients need to be delivered to muscles quickly and carbon dioxide removed; increased heart rate allows for this 16. People with better cardiovascular health will return to resting heart rate after exercise more quickly due to conditioning and a stronger heart

CHEMISTRY Chemistry is the study of matter . -It's composition structure, and properties -The process it goes through and the energy changes that occur Matter is anything that has mass and volume. -Mass= a measure of the amount of matter -Volume=a measure of how much space something takes up Everything is made of matter Atoms are the building blocks of matter. Atom= the smallest unit of an element that maintains the identity of the element. Exmaple= atmospheric nitrogen, N2 conatins 2 atoms of the element nitrogen. Element= a pure substance that cannot be broken down into simple and more stable substances(elements). Example= anything in the periodic table. Compound= a pure substance that can be broken into simple and more stable subtances(elements) Made from chemmically combining atoms of two or more elements. Example=H2O Matter Substance Mixture Element compound homogeneous. heterogeneous Subtances= pure -Fixed composition throughout -Same properties througNaCI, C6H12O6 Element = form of matter -on the periodic table -cannot be broken down into anything simplier or more stable -exist naturally as 1 atom(monoatomic) or two atoms Examples= C, O2, something Compounds= chemically combined atoms of 2 or more different elements. Fixed proportions, written as a formula. -Can be chemically broken into simplier and more stable subtances(elements) -Have different properties as a compound than the parts that make it up Example= NaCI, CO2, C6H12O6 Mixtures= combination Variable composition throughout Each component retains its unique properties. -Mixtures can be separated into substances -Examples= salt water, lemonde, blood, air Homogeneous mixture= even destribution" same" -Appears blended -can be physically broken down into different components -Solution: one subtance(solute) is dissolve into another(solvent) -Aqueous solution= when the solute is dissolved into water -Alloy: A sollution of metals -Examples: Lemonade, stainless steel. Heterogenous mixture: Uneven destribution" different" -Can be physically broken down into different components and often easily -components can often be seen or seperated out over time. -Examples: Salad dressing, paint, blood. Properties Extensive: depends on the amount of matter that it presents -Ex. Mass, volume, amount of energy, ect. -Aluminum can have a mass of 10g or a mass of 200g based on how much you have. Intensive= do not depend on the amount of matter that is present -ex. Density, melting point, boiling point, specific heat, ect. -Aluminum always has a density of 2.7 g/cm to the power of 3, regarless of if you have a few pieces versus giant sheets. Physical= can be observe without changing the identity of the subtance -ex. Density, boiling point, state, color -State of matter -solid: definite volume and defined shape -liquid: definite volume and undefined volume -Gas: Indefinite volume and indefinite volume. Chemical: Can be only be observed by changing the compositions/identity of the subtance. -ex. Reactivity, ability to decompose, instability. Physical changes: Chages in the substance that doesn't chnage its density -ex. Boiling, melting, dissolving, vaporizing, cutting. Chemical changes: Chance of a substance into another substance; when a chemical reaction occurs. -ex. Burning, oxidation, rotting, corroding, fermenting -chemical changes do not have a change in amount of mass/matter -law of conservation of matter: matter is never created or destroyed, it only changes form -chemical changes always cause a change in composition. Evidence of chemical reacton: -Release of light -sudden tempeture change -sudden color change -odor change -gas given off -sudden apperance of a solid -this solid that forms is known as a precipitate.
