Answer:
<em>The correct option is A) cadmium dosage</em>
Explanation:
In an experiment, an independent variable can be described as a factor which is changed naturally or by us to see its effect on the dependent variable. The dependent variable is the variable which is under study and depends on the independent variable.
In the following experiment, we are checking the effect of different dosages of cadmium on the surviving ability of tadpoles. Hence, cadmium dosage is the independent variable. Tadpole population is the dependent variable.

Action of insulin
Insulin plays an important physiologic role, especially in the liver, muscle, and adipose cells, in homeostasis of blood glucose concentration (4). For this reason, the liver, muscle, and fat have been regarded as major target tissues for insulin.
Answer:
Ya antes del fin del siglo XIX Ehrlich había usado el término "complemento" para designar la actividad del suero que podía complementar la capacidad de los anticuerpos específicos de lisar bacterias. Pero es Jules Bordet quien descubre (1895) este componente, caracterizado frente a los anticuerpos por su termolabilidad. En 1907 Ferrata comienza a caracterizar algunos de sus componentes recurriendo a métodos de diálisis. Por motivos meramente cronológicos, los componentes iban recibiendo denominaciones a base de números tras la letra "C" conforme se iban descubriendo. Por esta razón, su orden de actuación no guarda en general relación con su nomenclatura.
Explanation:
.Answer:
Option A, fix nitrogen inside nodules on the roots of legumes
Explanation:
Rizhobium bacteria live in symbiotic relationship with roots of leguminous plants such as pulses including alfalfa, soybean etc.
Rhizobium or Bradyrhizobium is a gram negative bacteria that satisfies the nitrogen starvation of host plant.
These bacteria get habitation and nutrition from these leguminous plants and in return they fix the nitrogen into the nodules of the roots. This is a kind of facultative association between soil bacteria rizhobium and legume plants.
Hence, option A is correct
Thus, option A is correct
