Prompt Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that shows
amino acid sequence differences between different organisms for a protein keratin Changes in amino acid sequences are known to cau
changes in structure of proteins.

Part A. Consider species A, D, and E Using the data provided, describe how the structures of their keratin proteins would compare.
Part B. Keratin is made up of about 450 amino acids. Determine the similarity in percentages between species A and B A and C, and B
and C. Explain how amino acid sequences can be used in determining how closely related two species are.
Part C. Based on this data, predict which two species would be more closely related to one another
gallns
Part D. Justify your predictions to part C

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells

Use the distance formula to determine weather each pair of segments have the same length
