The right option is a. contour interval
The difference in elevation between the highest and lowest contour lines on a topographical map is called contour interval.
A contour interval is the vertical distance between the two contour lines (highest and lowest) in a topographical map. The contour interval is usually stated explicitly on the right-hand lower part in every map. 20 feet for a 1:24,000 map scale is the frequently used contour interval and different contour intervals is available for different maps.
Answer: The options are not included.
But the sites are;
Interaction with ribosomes.
Interaction with aminoacyl tRNA
synthase.
Attachment of the specific Amino acid.
Interaction with codon.
Explanation:
Transfer RNA is a type of RNA that help to translate messenger RNA sequence into protein. Each tRNA have two major areas; the anticodon and region for attaching specific Amino acids.
tRNAs function at specific sites in the ribosomes during mRNA deciding.
The four specific recognition sites of trna that must be inherent in it's tertiary structures in order for it to carry out it's role are;.
Interaction with ribosomes.
Interaction with aminoacyl tRNA synthase.
Attachment of specific Amino acid.
Interaction with codon.
Answer:
Lungs.
Explanation:
Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..
