Answer:
Originally developed as an insecticide, it became infamous for its environmental impacts. DDT was first synthesized in 1874 by the Austrian chemist Othmar Zeidler. DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Müller in 1939.
Given –
Mg of iron tablets consumed = 50 mg
Number of tablets consumed = 2
So,
Total mg of iron tablets consumed = 2 X 50 mg
= 100 mg
Total grams (g) of iron tablets consumed = 100 X 0.001 g
Because 1 mg = 0.001 g
So,
Total grams of iron tablets consumed would be 0.1 grams.

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.
Answer:
Processing and storing food.
Explanation:
The coelom is the hollow structure formed in the organisms filled with the coelom fluid. The coelom is formed during embryogenesis which may be lined by the mesodermal layer or not.
The formation of coelom serves many functions in different organisms like it allows the internal movement of the organs in the body, allows the independent movement of the digestive tract, the fluid present in the cavity acts as a hydrostatic skeleton in the lower organism and cushions the internal organs.
The function that is not performed by the coelom is that it is not involved in the processing and storing food in organisms.
Thus, Processing and storing food is correct.
