Answer:
Antimicrobial peptides
Explanation:
Antimicrobial peptides may be defined as the important part of immune system that provide protection against the pathogens. These peptides are also known as host defense peptides.
Defensin and bacteriocins are the antimicrobial peptide. Defensin are cysteine rich protein that provide protection against bacteria, virus and cancer cells. Bacteriocin peptide is present in bacteria that inhibit the growth of the same strains of bacteria.
Thus, the correct answer is option (4).

Answer:
Both species are mammals and therefore they share genome regions and gene families that are conserved in the course of evolution.
Explanation:
Synteny enables to identify conserved genome regions between species by aligning their DNA sequences. For example, the human and chimpanzee genomes share about 95-98% of synteny (sequence similarity) in their DNA sequences. In this case, a whole-genome sequence similarity of 80 % is evidence that both species are relatively closely related and share a near common ancestor. Indeed, it is expected that the most part of the remaining 20% represents mutations associated with the fixation of neutral alleles (i.e., neutral mutations) and therefore have no evolutionary meaning.
Answer: Lactose intolerance is caused by a deficiency of the intestinal enzyme lactase that splits lactose into two smaller sugars, glucose and galactose, and allows lactose to be absorbed from the intestine.
