¿Cuáles son las ventajas y desventajas entre la agricultura intensiva y la biológica?
SVEN [57.7K]

Answer:

La agricultura intensiva puede eliminar rápidamente los nutrientes del suelo, que generalmente se repara con fertilizantes. La agricultura ecológica normalmente se refiere a no transgénicos

producción y falta de fertilizantes y pesticidas más dañinos. Por lo general, los productos orgánicos se venden a un precio más alto a las personas que creen que los conservantes afectan su salud y bienestar. Los productos intensivos generalmente se venden en grandes cadenas de mercado para obtener grandes ganancias y, por lo general, las frutas transgénicas se pueden producir en casi todas las estaciones.

intensive agriculture can remove nutrients from the soil quickly which is usually remedied by fertilizer. Organic farming normally refers to non-gmo

produce and lack of more harmful fertilizers and pesticides. Usually the organic produce is sold for a higher price to people who believe the preservatives affect their health and well being. Intensive produce is usually sold in large market chains for great profit and usually gmo fruits can be produced in almost all seasons.

<em><u>Explanation</u></em>

Isotope is two or more forms   of the same element  that  has  equal  amount of proton but different  number of neutrons  in the nuclei.

oxygen -17 and oxygen-18  are  isotope    of oxygen since they  have the equal amount   of  protons but different   number of  neutrons  in their  nuclei.

PLZ ANSWER
satela [25.4K]

Answer:

B. The student should model a convex lens because it directs light toward the center of the lens.

Explanation:

Lenses are optical devices that work on the principle of refraction.

Refraction is a phenomenon of wave (such as light waves) that occurs when a ray of light crosses the interface between two mediums with different optical density: when this occurs, the ray of light bends and change speed.

In particular, there are two types of lenses:

  • Convex lenses: these lenses are curved outward at their center, therefore the rays of light coming from infinite distance (parallel to the axis) are all focused into a point of the lens, called principal focus. Therefore, a convex lens directs lights towards this point.
  • Concave lenses: these lenses are curved inward at their center, therefore the rays of light coming from infinite distance are bent away from the principal focus. Therefore, this is a diverging lens, as the rays of light do not converge.

So, the correct answer is

B. The student should model a convex lens because it directs light toward the center of the lens.
