fredd [130]

Answer:

Las unidades de Mendel se conocen ahora como GENES

Explanation:

Durante sus experimentos, Mendel demostró que las características de las plantas de guisante (por ejemplo color de la flor, color de la semilla, forma de la semilla, altura de la planta, etcétera) eran heredadas, y denominó "elementos" a las unidades portadoras de dichas características. Es decir que cada elemento o unidad discreta, era el responsable de que la planta exprese una u otra característica. Estableció que estos elementos se redistribuían independientemente uno de otro, generación tras generación. Con el paso del tiempo y el avance de las investigaciones, estas unidades o elementos fueron denominados <em>Genes</em>.

Stolb23 [73]
Some isotopes, however, decay slowly, and several of these are used as geologic clocks. Dating rocks by these radioactive timekeepers is simple in theory, but the laboratory procedures are complex. <span>All methods rely on the fact that certain elements (particularly uranium and potassium) contain a number of different isotopes whose half-life is exactly known and therefore the relative concentrations of these isotopes within a rock or mineral can measure the age.</span>

10

Explanation:

The Ritcher scale is a logarithmic scale and it suggests that the number increases by a factor of 10.

One point on the scale differs from another by an order of 10.

  • The Ritcher scale is used to measure the magnitude of earthquakes in a particular area.
  • It is graduated form 1 to 10
  • The magnitude of the quake increases as one moves from 1 through 10.
  • This is because the magnitude of the quake actually increases by an order of 10.
