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.

In studying the gene pool of a population, you find that 21% of the population exhibits the recessive trait for eye color and th
Naily [24]
In order to solve this problem we use these formula:
<span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population
q = % recessive allele in the population
p2 = % homozygous dominant individuals
q2 = % homozygous recessive individuals
2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>

Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. ... Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.

What is natural selection (not from google) give an example of what natural selection is
ruslelena [56]
Natural selection is nature’s way of keeping the best fit-to-live things alive, and so on continue to the next generations.

For example, if a rabbit has a limp, it is bound to be out run and eaten by a predator relatively early in its life (unless it is extremely lucky.) Because of this, it is unable to reproduce, and there genes that it contained to have its limp are unable to spread through inheritance. Natural selection goes both ways. For example, if a hawk has very god vision, it will be able to scope out its prey easily, so it will thrive. Therefore, when it produces offspring of its own, its trait of good eyesight will pass on to its offspring.

So, as enough time goes on, the bad traits will be weeded out and the good ones will remain.
