According to most scientists, green algae are the ancestors of plants. Which statement best supports that belief? A) both have c
Tresset [83]

The statement that best supports that belief is “both have cell wall made of cellulose, store food material as starch, and have chlorophyll a and chlorophyll b”.

 

The green algae are a large, informal grouping of algae consisting of the Chlorophyte and Charophyte algae, which are now placed in separate Divisions. The land plants or Embryophytes are thought to have emerged from the Charophytes.

 

The correct answer between all the choices given is the first choice or letter A. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

FinnZ [79.3K]

Answer:

Nuestro planeta esta habitada por numerosas <em>especies</em>, muchas de ellas extendidas en grandes y diversas zonas. Sin embargo, existen especies que habitan una sola <em>área/región</em> con características<em> ambientales</em> únicas para su desarrollo.

Explanation:  

Entre las miles de especies que habitan el planeta, muchas de ellas pueden estar ampliamente distribuidas, mostrando adaptaciones a una gran variedad de ambientes y hábitats, mientras que muchas otras solo se encuentran restringidas a determinadas areas o regiones particulares que presentan condiciones ambientales determinadas. Esta diferencia en distribución esta muy relacionada a la historia de la especie,  a la edad de la misma sobre la tierra, adaptaciones a los ambientes y capacidades reproductivas y de dispersión.

Dentro de la clasificación de especies de acuerdo a su distribución, podemos mencionar a las especies

  • nativas: aquellas que habitan y se distribuyen las áreas naturales donde se originaron,
  • endemicas: entran dentro del concepto de nativas, pero a parte se caracterizan por habitar <u><em>unicamente</em></u><em> una región en particular debido a las condiciones ambientales</em> que les son propicias para su desarrollo. Estas especies no pueden trasladarse a otras regiones.
  • exoticas: aquellas especies que salen de su area natural de distribución para habitar otras areas mas lejanas. Allí pueden establecerse e interactuar con especies nativas sin causar grandes daños.
  • invasoras: especies exoticas que llegan a otras areas, que se establecen y que tienen la capacidad de reproducirse a una tasa superior a la de las especies nativas, invadiendolas y desplazandolas. Interactuan con las especies nativas y causan daños importantes.

Los términos nativos, endemicos, exóticos son <em>relativos al área a la que se esté haciendo alusión</em>: un continente, un país, una región o un bioma.

What can you say about the environments of these widely seperated layers
Alika [10]

Answer:

This means that the two separate rocks were once part of one piece of rock. These layers got separated most probably by continental drift as a result of tectonic plate movements. An example of such a fossil is the Mesosaurus, a freshwater crocodile-like reptile, that is found in Southern Africa and Eastern South America continents- that means they were once one land mass.

The environment in these two separate layers would most likely be different. As the layers drift apart from each other , they drift across latitudes that are determinants of climate in a region. Therefore, even the organisms in these two rock layers will evolve differently (even though they will share a common ancestor) in adaptation to respective environments – this is called allopatric speciation.
