endocytosis and exocytosis
list the steps that make up an organism
cell
tissue
organs
organ system
organism
an organisms internal environment is kept stable in spite of changes in the outside environment is called
homeostasis
how many cell theories are there and name them
three
all living things are made of cells
cells are the basic units of structure and function in living things
all new cells are produced from existing cells
what’s the difference between plant and animal cells
animals cells do not have a cell wall but plants do
what are all the stages for cell cycle hint: PMAT
prophase
metaphase
anaphase
telophase
which system guards against infection and injury; helps regulate body temperature
integumentary system
name two things that respond when your temperature starts to fall too low it doesn’t need to be the same answer it just needs to be something that ACTUALLY makes sense
you get goosebumps and start to shiver

the molecules move from an area of low concentration to an area of high concentration
what’s something that uses no cell energy and is a form of passive transport
facilitated diffusion
why do white blood cells produce in your bone
to attack and destroy bacteria and other causes of diseases
