All living organisms share many characteristics necessary for life. for example, all organisms, including both prokaryotic and eukaryotic, can sexually reproduce to produce unique offspring. can use abiotic factors to make their own food. have cells arranged into complex organ structures. must obtain and use energy for life processes.

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
