Answer: 20 amino acids
Explanation:
The Genetic code permits the triplet nature of codons whereby three nucleotides from Adenine, Uracil, Guanine and Cytosine on the messenger RNA (mRNA) join to form 64 codons.
Since more than one codon can specify for an amino acid, the 64 codons then specify for 20 amino acids, that then form the sequence of various proteins
The human cell has the largest surface area to volume ratio is Sperm cell or spermatozoa and its ratio is 1.55
<u>Explanation:</u>
Spermatozoa is a uni-flagellar motile sperm cell that basically determines the sex of an offspring. It moves from the haploid male gamete,its contributes in 1/2 nuclear genetic information to diploid.
The surface area of sperm cell is measured by micro-metric method or electron mircographs using stereo-logical method. While the volume will be measured by stereology or radio label volume exclusion method. The volume and surface area inversely proportional to cell size.
Marijuana
Marijuana is a psychoactive drug and it includes the dried leaves, seeds, stems and flowers, from the Cannabis sativa or Cannabis indica plant. Marijuana is a federal illegal drug and it contains tetrahydrocannabinol (THC); a compound that has intoxicating effects and other similar compounds.
