Answer:
Prokaryotes have a nucleus, Eukaryotes don't
Explanation:
(see image)
The genes are from the nuclei of the egg (from the female) and the sperm (from the male) the different traits are joined to create the particular genes.
(I might be right.)
The isotope has a half-life of 5730 years.
In 5730 years, the isotope (Carbon-14, to be more exact) will lose 50% of its mass, meaning that in 11460 years, 25 grams of Carbon-14 will remain.
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.
