Answer:
31%
Explanation:
Chargaff's law says the amount of A (adenine) = T (thymine) and G (guanine) = C (cytosine). If
G = 19% then C= 19%
19% + 19% = 38%
100% - 38% = 62%
62% for A and T
Divide by 2 and you get
31%
Ribosomal RNA is produced by nucleolus<span>. Ribosomal RNA associates with a set of proteins to form ribosomes. They physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. Additionally, they bind tRNAs and various accessory molecules necessary for protein synthesis. Nucleolus is the structure within the nucleus that is responsible for the formation of these complex structures. The DNA is transcribed into ribosomal RNA precursor molecule which is later processed into mature rRNA. </span>
The bones that form the prominences of the cheeks as well as part of the lateral wall and floor of each orbit are the Zygomatic bones.
The zygomatic bone is proportionately small but structurally important. It is almost quadrangular in shape and it is characterized by three surfaces, five borders and two processes.
It conveys the pressure exerted on the zygomatic region towards three otherwise unconnected bones i.e. the maxilla, the frontal as well as the temporal bone.
The zygomatic bones also possess the system of canals for the branches of the zygomatic nerve. The zygomatic bone extends backward to join the zygomatic process of the temporal bone, making the zygomatic arch.

The evaporation process uses the sun radiation or sun’s thermal energy for vaporization of a water from the land or soil to be water vapor then in the air. Transpiration on the other hand is the same with evaporation that involves water molecules to be vaporized into the air but it is located in the stoma of the plants. It is like evaporation within plants. This is actually to have homeostasis in plants and still part of the water cycle. </span>
