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 Bear population would increase due the the raise in the salmon population.
Answer:
the competitive exclusion principle
Answer:
D. when each chromosome is duplicated
A compound is always a substance because it's made out of two or more atoms bonded together. Now a substance isn't always a compound because it takes two or more elements to create a compound in a chemical reaction, ans substances can contain only one element. In other words a substance can be constructed of one type of atom. Some substances that aren't compounds are: gold and baking soda.
