Answer:

Hydroponic gardens don't use soil, whereas normal gardens always have soil as their matrix.

Explanation:

Hydroponic gardens receive a constant supply of water and nutrients in concentrations determined by the gardener. These run constantly by tubes where the plants are inserted and they uptake what they need by their submerged roots. On the other hand, normal gardens use soil as the matrix from where plants have to uptake water and nutrients.

¿qué propiedades tomó en cuenta John Newlands para clasificar los elementos de la tabla periódica?

liubo4ka [24]

Answer:

John Newlands propuso su ley de octavas en 1864 en la que organizó todos los elementos conocidos en ese momento en una tabla en orden de masa atómica relativa. Cuando hizo esto, descubrió que cada elemento era similar al elemento ocho lugares más adelante.
