Answer:
eight (8)
Explanation:
A phenotypic ratio of 9:3:3:1 is predicted from a cross of AaBb x AaBb (i.e., in a dihybrid cross). In this case, the expected phenotypic ratio is equal to:
A_B_ (9:3:3:1) =71.43 >> 71 both dominant phenotypes
aaB_ (9:3:3:1) = 23.81 >> 24 one dominant phenotype
A_bb (9:3:3:1) = 23.81 >> 24 one dominant phenotype
aabb (9:3:3:1) = 7.93 >> 8 both recessive phenotypes
Expected phenotipic ratio (9:3:3:1) = 71 + 24 + 24 + 8 = 127
Kidney. - Filters our blood.
Bladder. - Stores urine until urination

Answer: Natural Selection
Explanation:
Natural Selection is the process by which the chances of the fittest organism to survive increases and rest of the organisms has less chances of survival.
The diversity of the organisms increases the survival rate of the organism. The natural selection shows that the fittest organism will have a greater probability to survive.
The more stable the organism more will be the probability of the organism to resist the change.
