There was low concentration of salt in the water compared to the cell because when blood cells are put in a hypotonic solution like pure water can cause the cell to swell up and burst due to the little concentration on no concentration
Alright so three different alleles are A, B, and O.
A dominant to O
B is dominant to O as well
O is recessive to A and B
Increased heart rate,Increased thirst, and increased salt hunger.
Good luck! (:
Salutations! 1) A. The primitive earth had a lot of UV radiation. Photosyntesis originated O2 and O2 reacts generating O3 (ozone). The ozone layer prevents a lot of UV radiation to reach inorganic molecules and provide them with a lot of energy. Without that intense UV radiation, inorganic molecules cannot convert into organic molecules (because no other source of energy provides enough energy for that process). Hope this helps you!
