entrance exam practice test

• function of the pancreas: produces enzymes that help to digest food, particularly protein
• carbon monoxide: competes with oxygen for binding with red blood cells
• solution: homogenous mixture
• universal solvent: water
• pH level of 7: neutral
• pH level of 0: most acidic
• pH level of 14: most basic
• solar eclipse: when the moon is in between the sun and earth
• ears: most closely associated to the nervous system
• phototropism: the ability of the plant to re-orient the shoot growth towards a direction of light source
• thigmotropism: the growth of a plant in response to touch, caused by the release of auxin
•  geotropism: growth of the parts of plants with respect to the force of gravity
• hydrotropism: movement of roots toward water
• monocot plants: grass and grass-like flowering plants, the seeds of which typically contain only one embryonic leaf, or cotyledon
• ornithology: study of birds
• phloem: vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
• cutting a ring of bark around the trunk of the tree will essentially affect the function of the phloem
• humus: organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms.
• acceleration: change of velocity in a given time
• inertia: tendency to remain at rest or continue moving with constant speed unless acted upon by an external force
• newtons first law of motion/ law of inertia: an object at rest or in motion will stay that way, unless acted upon by a net external force or an unbalanced force
• newtons second law of motion/ law of acceleration: The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass.
• newtons third law of motion/ law of action and reaction: for every action there is an equal and opposite reaction. 
• density: amount of matter in a given space
• madame marie curie: discovered the radioactivity of uranium
• psychrometer: weather instrument used to measure the relative humidity using the cooling effect of evaporation
• mycorrhiza: symbiotic association of fungi and roots of plants
• entomology: study of insects
• symbiotic relationship: the 2 organs live closely to each other
• eratosthenes: greek mathematician and astronomer who is known as the first person to accurately measure the circumference of the earth
• sea-floor spreading: formation of new crust on the ocean
• earth has a stronger gravitational pull than the moon\
• the ozone layer is located in the stratosphere and is a layer of ozone gas
• law of inertia: when runners crossing the finish line of a race often take time before they completely stop
• salt and sugars: prevents water from being available to microorganisms
• potato: underground root that DOES NOT function for food and/or water storage
• ear: where the smallest bones (hammer, anvil, and stirrup) are located
• atomic mass of an atom: represented by the number of protons and neutrons
• the number of chromosomes in your gametes is half of the amount of chromosones in your skin
• triassic: period of the mesozoic era when dinosaurs first evolved
