Answer:
The expected ratio of the F_2 generation from F_1 generation will be
<u>9 "fabulous": 3 "smashing": 4 "plain" </u>
Explanation:
The expression of the phenotype will follow Mendel's Dihybrid cross.
plain→smashing
(only when allele A is present, which produces Enzyme 1)
smashing→fabulous
(only when allele B is present, which produces Enzyme 2)
Keeping the above statements in mind, in F_2 generation, only the genotypes having both A and B alleles will express phenotype "fabulous",as both Enzyme 1 and Enzyme 2 are required for that. The genotype having at-least one A allele and no B allele will produce the phenotype "smashing", as Enzyme 1,produced by allele A, will convert "plain" into "smashing". Hence, the dihybrid cross will as in the attachment.
Zoe is frying eggs in a pan. The eggs cook because of Conduction(a) of heat. Zoe feels hot as she stands near the stove mostly because of Radiation(c) of heat.

Answer:
During synthesis phase DNA replication occurs to doubles the amount of DNA.
Explanation:
Interphase is the phase where the cell spends most of its time. Interphase is divided into three-phase which are G1, S, and G2 phase. The cell grows and produces enzymes required for DNA replication in G1 PHASE.
The synthesis (S) phase is the phase where the DNA replication takes place. Due to DNA replication, the amount of DNA gets doubled in this phase. DNA replication is important because after mitosis cell divides into two daughter cell in which the two DNA divides equally which creates two identical cell after cell division.
Natural selection acted on developmental regulatory genes that determine gill arch morphology..
Answer: C. .6 ounces
In the United States, a standard drink is a criteria which states the amount of alcohol that should be present in an alcoholic drink. A standard alcoholic drink should contain 14 gram equivalent to 0.6 ounces of pure alcohol.
