If the gametes produced by a given organism contain 6 chromosomes, how many chromosomes are found in that organism's body cells? (4 points) 3 6 12 10

hi

gamete are reproduction cells.  They carry only half of the DNA materials

for the merger with an other gamete celle from the opposite sex.

so if a gamete carries 6 chromosomes, normal load of other cells is 12

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
