Answer:
1. Doldrums: This area is located around the equator and is relatively calm.
2. Polar Easterlies: This wind occurs near the poles and is cold and dry.
3. Westerlies: These winds are in the middle latitudes and originate from the high pressure of horse latitudes.
Explanation:
The above mentioned elements are associated with the atmospheric weather condition of a place over a period of time.
The answer for this question is "founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results" so it is letter A
Uranium is a heavy material used to create nuclear energy, when nuclear fission occurs, Uranium releases a lot of energy, that is used to produce thermal energy.
Answer:
Prokaryotic gene expression:
The transcription of prokaryotes is different from the ekaryotes. Prokaryotes use the promoter sequence located at -10 and -35 position upstream of the DNA. The transcription is coupled with translation in prokaryotes in the cytoplasm. The spilicing of mRNA do not occur in eukaryotes.
Eukaryotic gene expression:
The regulation of transcription in eukaryotes is different from prokaryotes. The eukaryotic mRNA undergoes splicing and 3' polyadenylation and 5' capping occur in prokaryotes. Different kinds of RNA polymerase is required for the transcription of different RNA molecule. The transcription occurs in the nucleus.
Answer:
GG, Gg, Gg, gg
Homozygous green – GG
Heterozygous green – Gg
Homozygous yellow - gg
Explanation:
It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.
The genotype of the true breeding Green plant is “GG”
The genotype of the true-breeding yellow plant is “gg”
F1 generation cross
GG * gg
Offspring produced from F1 generation are – Gg, Gg, Gg, Gg
In f2 generation offspring of F1 generation are crossed among each other.
So the offspring produced in F2 generation are
Gg * Gg
GG, Gg, Gg, gg
Homozygous green – GG
Heterozygous green – Gg
Homozygous yellow - gg
