Question | Answer |
enzymes | proteins that speed up chemical reactions by lowering the activation energy. controls the rate at which food is broken down in our body |
lipids (fat) | biomolecule used for energy and insulation |
enzymes | directly control the rate at which food is broken down |
pseudopod | structure in ameoba used for movement by cytoplasmic streaming |
organic molecules such as carbohydrates, proteins and lipids | contain carbon |
negative chemotaxis | moving away from a harmful chemical |
activation site | the part of the enzyme substrate complex where the enzyme binds with the substrate |
passive immunity | when an individual receives pre made antibodies. example mother passing immunity to baby through breast milk. |
kidney | used in complex animals to remove excess water and nitrogen |
xylem and phloem | transport structure in plants similar to the blood vessels in humans |
contractile vacuole | structure in protist used to excrete excess water, similar to the excretory system in humans. |
lungs and moist skin | allow for respiration on land |
transpiration | how plants move excess water and oxygen out of their leaves, similar to respiration in animals |
guard cells | cells that surround the stoma and prevent excess water loss by closing the stoma |
endoskeleton | skeleton that grows with the organism allows organism to reach a much larger size |
exoskeleton | protective outer structure that must be shed each time the organism grows |
gills | allow for respiration under water |
nonvascular plants | must use diffusion to get materials into and out of cells |
cilia | hair like structures that allow single cell organism to move |
eyespot | structurs in euglenas that allow them to detect light |
small intestine | Structure used for absorption of nutrients long in length, projections to increase surface area |
diffusion | what microorganism use for transport since there is no circulatory system present |
salivary amalayse | enzyme in the mouth that dissovles food so we can taste it |
contractile vacuole | allows unicellular organims to excrete excess water so they don't explode |
antiviral | medicine that slows down the rate at which a virus can replicate so decrease the length of the disease |
active immunity | immunty in which the organims must make their own antibodies, last a life time. examples are vaccines and getting sick |
