yulyashka [42]

Answer:

B. The mutation results in a new, dominant allele

C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.

D. The mutation occurs in a codon and alters the function of the final protein

Explanation:

All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.

Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.

This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.

Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.

marin [14]

Answer:

En resultados

Explanation:

El experimento se basa en analizar el movimiento de la planta en respuesta a la luz solar, desde distintas posiciones:

  • 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.
