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
The answer is

Answer:
ecosystem diversity
Explanation:
sorry if wrong-tried my best
The greenhouse effect occurs when rays enter our atmosphere and are reflected from the ground up. They get changed during their voyage through our atmosphere and they change in such a way that they can't leave the atmosphere anymore. Then they stay inside and heat up the planet which causes thing like global warming. That's what the greenhouse effect is.
Answer:
part a
A= Tt
B=tt
part b
offspring a
genotype= TT&Tt, phenotype=tongue rolling
offspring b
genotype=Tt phenotype= tongue rolling & genotype tt phenotype= unable to roll tongue
