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 and Explanation:
1. The biggest similarity between the main types of vertebrae is the location where they are found since they are all established on the body's back, precisely on the midline of the back. The main differences, on the other hand, are related to the size and weight of each of them.
2. The similarities exist because all the vertebrae have to promote the support of the body, the back being the most appropriate place for them to establish themselves.
3. The differences are related to the function and type of support that each vertebrae promotes, the higher the level of systemization, the larger and thicker the vertebrae must be.
4. The caudal vertebrae should be similar to the vertebrae of the coccix, since a tail would be a representation of elongation of the coccix. We can reach this conclusion through the analysis of images that promote the visualization of this area of the body.
Answer: The correct answer is cortex
Explanation:
The glomerulus and the bowman’s capsule are both located in the Cortex, one of the two main regions of the kidney, alongside the Medulla.
The glomerulus is a mass of blood capillaries linked to urinary tubule, while the Bowman's capsule is a cup-shaped structure. The glomerulus filters materials such water, urea, glucose ET into the bowman's capsule in a process called ultrafiltration, a necessary step in urine formation.
