cell: basic unit of structure & function in a living thing
tissue: a group of similar cells that are organized to do a specific job
organ: a collection of tissues that carry out a specialized function of the
body
organ system: group of organs that work together to perform a specific
function
organism: a living thing made of a group of organ systems
◉ What are the characteristics of life and define each. Answer:
Responsiveness to the environment, growth and change, ability to
reproduce, have a metabolism and breathe, maintain homeostasis, being
made of cells, passing traits to offspring
◉ what are the requirements of life? why is each important? Answer:
water: needed to transport substances to regulate the body
food: needed to supply energy and for regulation
,oxygen: needed to help release energy from food substances
heat: needed to regulate the rate of metabolic processes
pressure: needed for breathing and circulation
◉ Define homeostasis. Answer: Maintaining a stable internal
environment

differences between the three? Answer: covalent: 2 atoms shared 1 or
more molecules
hydrogen: weak bond between 2 opposite positively charged sides of 2
or more molecules
ionic bond: atom gives away one or more electrons to another atom
◉ Define synthesis. Answer: the production of chemical compounds by
reaction from simpler materials.
