<span>The frog population in the Amazon basin varied. Every 500 years there was a mutational change leading to speciation. In between the population remainedthe same with no observable changes. The pattern of macroevolution is that there is a change in species orientation and adaptation to change</span>
Answer:
Inappropriate activation of telomerase can result in cellular immortality, one of the cellular changes implicated in the development of cancer.
Explanation:
Some studies show that when telomerase activity is stimulated and a tumor suppressor gene (the p16INK4a gene) is inactivated, cellular immortalization occurs, which constitutes an important step towards the formation of a tumor.

Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.
Explanation:
Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.
