We can infer of the two paragraphs that Geological movements are often hazardous when they happen quickly, and that the movement of plate boundaries does not always cause disaster.
The excerpt is telling us that "the <span>earthquakes caused a lot of damage, as well as dramatic changes to the local ecosystem", which is supporting the conclusion: "geological movements are often hazardous when they happen quickly."
But is also telling us that "</span>The slip caused several rock formations and structures to develop cracks. However there was no large-scale disaster or disruption.", which is supporting the conclusion: the movement of plate boundaries does not always cause disaster."
Question continuation;
..........type B. Type A is found to be more common in the mainland population from which the island was settled.
How could a geneticist best explain the dominance of blood type B in the island population?
Multiple choices;
A. Random mutations have occurred in the island population.
B. Genetic drift has reduced the frequency of type A individuals.
C. Natural selection has only occurred in the mainland population.
D. Environmental conditions on the island are less favorable for type B individuals.
Answer;
B. Genetic drift has reduced the frequency of type A individuals.
Explanation;
-Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance.
-It occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Bacteria produce restriction endonucleases, or restriction enzymes, that recognize and cut up foreign DNA, including certain phage DNA.
Answer:
The correct answer is :
- The 2 strands of DNA separate
- mRNA is built based on the DNA template
- tRNA brings an amino acid into the P site.
-
tRNA brings an amino acid into the A site.
-
tRNA leaves the P site and a peptide bond is formed between the amino acids.
- The mRNA+attached tRNA shifts, moving the 6-tRNA from A site to the P site.
-
The entire mRNA strand is translated into amino acids and a polypeptide is formed.
Explanation:
Protein synthesis is a process that is made up of two distinct processes namely transcription and translation.
Transcription: this process include several steps where the segment of DNA which has information, copied into the new molecule called mRNA which acts as the template as it has information copied from the DNA to produce gene expression.
Translation: is the process includes several steps in which a peptide chain is formed from the mRNA with the help of tRNA and ribosomes.
The correct order of steps is given under the answer heading.
