Answer:
C. Beak size is an inherited trait in the finch population under study.
D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.
E. Beak size varies among the birds in the finch population under study.
Explanation:
The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.
If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.
Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.
The answer is A. I hope this helps.
Answer:
The correct order is - codon recognition, peptide bond formation, translocation
Explanation:
During the translation process mRNA is translated to proteins with the help of ribosomes. Protein formation occurs in three stages.
1. Codon recognition: In the codon recognition ribosome allows the binding of only that aminoacyl tRNA which has complementary anticodon against the mRNA codon.
2. Peptide bond formation: The peptidyl group present on the P site of the ribosome is transferred on the new aminoacyl tRNA present on A site by Peptide bond formation.
3. Translocation: In translocation, the tRNA present of P site and A site are transferred to the P site and E site of the ribosome to accompany the binding of new tRNA on A site.
