In response to seasonal changes in temperature, many organisms must alter the composition of their plasma membranes to maintain
katrin [286]

Answer:

The correct answer is D

Explanation:

The cell membrane is essentially composed of the following:

  • phospholipids
  • cholesterol
  • proteins

The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.

There are 3 main factors that greatly influence the fluidity of the plasma membrane:

  • temperature
  • cholesterol
  • saturated and unsaturated fatty acids

Lee la siguiente situación, y diseña un experimento. (No tienes que realizarlo)
Lynna [10]

Answer:

- Luis quiere saber si los cristales de yodo pueden disuelverse en distintos líquidos  

- Luis necesita cristales de yodo, agua, alcohol y aceite mineral

- La hipótesis de trabajo puede ser: "los cristales de yodo se disuelven en distintos líquidos", con lo cual la hipótesis alternativa indicaría que los cristales de iodo no se disuelven

- La recopilación de los datos puede consistir en la realización de tres experimentos en los cuales los cristales de yodo son sumergidos en agua (1° experimento), alcohol (2° experimento) y aceite (3° experimento).  

Explanation:

En el método científico, la pregunta científica refiere a una cuestión particular la cual es planteada con el objetivo de responder algún aspecto particular del mundo real. A partir del planteamiento de una pregunta científica es posible formular dos hipotésis denominadas hipotésis nula e hipótesis alternativa, las cuales representan supocisiones contrapuestas que permiten contestar dicha cuestión. Subsecuentemente, los científicos realizan experimentos y/o observaciones que permiten recopilar datos cuyos resultados son utilizados para confirmar (o rechazar) la hipótesis nula. Por otra parte, es necesario resaltar que durante el proceso de experimentación se requiere de la utilización de controles positivos y negativos que permitirán corroborar si dichos experimentos fueron realizados correctamente.
