Explica el impacto del desarrollo de las técnicas moleculares en los sistemas de clasificación de los organismos.
docker41 [41]

Answer:

Las técnicas moleculares, especialmente aquellas basadas en la manipulación del material genético, permitieron automatizar el proceso de identificación y clasificación de especies

Explanation:

Las técnicas moleculares usadas para la clasificación de organismos son aquellas principalmente relacionadas a la manipulación de su material genético. En especial, las técnicas de extracción de ADN, amplificación mediante la reacción en cadena de la polimerasa (PCR) y posterior secuenciación han posibilitado automatizar el proceso de clasificación de organismos. Los marcadores moleculares de ADN basados en secuencias génicas evolutivamente conservadas tales como, por ejemplo, la secuencia del gen Citocromo Oxidasa I (COI) en animales, son ampliamente usados para automatizar este proceso de identificación y clasificación de nuevas especies.

MariettaO [177]

Answer:

The correct answer is - characteristics of all vertebrate animals.

Explanation:

Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.

The only characteristic among these that present in both is that they both immune systems found in all vertebrates.
