Answer:
125.6
Explanation:
Area of a circle = πr^2
Area of circle 1 = 3.14 × 11 × 11
=379.94cm^2
Area of circle 2= 3.14 × 9 ×9
=254.64cm^2
Area of a shaded region
=379.94cm^2 - 254.64cm^2
=125.60cm^2
Answer:
plate margin (plate boundary) The boundary of one of the plates that form the upper layer (the lithosphere) and together cover the surface of the Earth. Plate margins are characterized by a combination of tectonic and topographic features: oceanic ridges, Benioff zones, young fold mountains, and transform faults.
The correct answer is D) The codon AUG must be identified.
What must occur for protein translation to begin is that the codon AUG must be identified.
The process starts when the 5AUG or start codon is identified. In the polypeptide chain, the 5AUG is the first amino acid. We are talking about Transition, the process when the genetic code in an RNA molecule has to be decoded in a polypeptide chain in order to deliver an amino acid sequence. In this complex transition system, there are important components included such as ribosomes, transfer RNA, and mRNA.
Out of the following given choices;
A. DNA accumulates mutations at a regular rate
B. known mutation rate for a gene
C. the number of differences in DNA sequences for a gene in two species
D. the same gene identified in two species
E. All answers are corrects
The answer is E. The molecular clock used rates of mutation to determine the prehistoric time when two species that share a common ancestor diverged. The benchmarks for determining the mutation rate are often fossil or archaeological dates.
