The nitrogenous bases in DNA are adenine, guanine, thymine, and cytosine.
The nitrogenous bases in RNA are adenine, guanine, uracil, and cytosine.
So the base in RNA that is different than in DNA is uracil.
Hope this helps.
Gregor Mendel lived in an Austrian monastery and tended the monastery garden. In 1865, through his observations of the garden pea plants that grew there, Mendel developed three basic principles that—although ignored at the time by his scientific colleagues—would later become the foundation for the new science of genetics.Every pea plant contains both male and female reproductive parts and will normally reproduce through self-pollination.
Explanation:
Having filtered out small essential molecules from the blood - the kidneys must reabsorb the molecules which are needed, while allowing those molecules which are not needed to pass out in the urine. Therefore, the kidneys selectively reabsorb only those molecules which the body needs back in the bloodstream.
