<h2>ANSWER:</h2>

Active transport

<h2>EXPLANATION:</h2>

Adapt extinct mutation

That organism will survive in the future which adapt themselves according to the environment.

<h3>What is fitness?</h3>

Fittest is the term describes living things that are best suited to their environment.

Species that survive are the ones that adapt, make or meet changes.

Florida has a rich fossil record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the giant sloth and the saber-tooth tiger.

Some animals unable to adapt to the changing environment became extinct .

Living things mutate over time to meet their changing environment.

This biologist, Darwin, studied evolution in the 1800s.

The glyptodont was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about natural selection.

Nature selects the fittest for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a mutation.

Oldfield mice show variation in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called adaptation.

Evolution is a controversial theory that has survived much criticism.

En las clases de ciencias estan hablando de varios movimientos que presentan las plantas debido a estimulos de ambiente, Pedro p

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.

Chloroplasts are organelles that are responsible for the photosynthetic functioning of an organism.Photosynthesis is the process by which an organism uses the photons to produce energy. These organisms uses the sun, together with the acquired resource of water and carbon dioxide to create sugar and process into energy.
