Marina CMI [18]

Answer:

A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.

Explanation:

Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.

The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.

If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.

  • planta parada
  • planta semiacostada
  • planta acostada

Durante su experimento, Pedro debe ir registrando los movimientos que observa en las distintas plantas a medida que recibe la luz del sol. El registro de dichos movimientos ante el estímulo forma parte de los resultados.

- Objetivo o propósito del trabajo: analizar la influencia de la luz solar como estimulo para generar un movimiento en plantas desde distintas posiciones.

- Procedimiento: Ubicación de plantas en distintas posiciones y bajo las mismas condiciones ambientales. Exposición de todas las plantas a la misma cantidad de radiación solar. Observación del movimiento durante un periodo de tiempo determinado.

- Resultados: Registro del movimiento de cada planta en cada posición durante el periodo de tiempo que fueron expuestas a radiación. En esta instancia de vuelca en tablas o gráficos, o se describe qué fué lo que se observó durante el experimento. Cuál fue la respuesta de cada una de las plantas.

- Conclusión: Relación entre lo esperado y lo observado. Comparación con otros trabajos similares.
