The goal of the World Resources Simulation Center (WRSC) is best described as: C. determining how to manage global resources for all humanity.
<h3>What is the World Resources Simulation Center (WRSC)?</h3>
The World Resources Simulation Center (WRSC) can be defined as a non-profit visualization and simulation facility that is saddled with the responsibility of availing individuals an opportunity to view critical trends about global global resources.
This ultimately implies that, the goal of the World Resources Simulation Center (WRSC) is best described as determining how to manage global resources for all humanity.

Answer:
1. The difference between the normal hemoglobin protein DNA sequence and the sickle cell hemoglobin DNA sequence is a base to base shift, in this case adenine (GAG) to thymine (GTG).
2. The difference affects the amino acid sequence of the protein by replacing glutamic acid (Glu) with valine (Val).
Explanation:
In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the amino acid sequence of globine β, incorporating valine instead of glutamic acid. This represents a molecular mutation - point mutation - by subtitution, which corresponds to missense mutation.
<u>Normal hemoglobin protein in a RBC</u>
DNA CTG ACT CCT GAG GAG AAG TCT
Amino acids Leu Thr Pro Glu Glu Lys Ser
<u>Sickle cell hemoglobin protein in a RBC</u>
DNA CTG ACT CCT <em>GTG</em> GAG AAG TCT
Amino acids Leu Thr Pro <em>Val</em> Glu Lys Ser
When GAG is transcribed to mRNA, the CUC codon is obtained, which codes for glutamic acid. Thymine substitution causes the DNA sequence to change to GTG, which is transcribed as CAC, the codon that encodes the amino acid valine. The <u>change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease</u>.

Answer:
Down syndrome occurs when the nondisjunction occurs with Chromosome 21. Meiosis is a special type of cell division used to produce our sperm and egg cells.
