Cell division is preceded by two growth phases. besides growth, both g1 and g2
a) contain checkpoints that determine if the cycle will continue.
b) move chromosomes to the new daughter cells.
c) produce more chromosomes before the cell divides.
d) grow and produce enough cytoplasm to fill two cells.

sexual reproduction produces offspring with novel combinations of genes. species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
