In an experiment, using the elodea stalk, you are able to expose more underlying tissue and the process can be executed more quickly and it's easy to replicate the natural position for a more realistic result.
hope this helps

A geochronological scale measured in Millions of Years Ago or M Y A. Mesozoic era: Triassic period, 250 to 201 MYA, first dinosa
motikmotik

Answer:

<em><u>D. The first flowering plants were introduced toward the end of the Mesozoic era.</u></em>

<em><u /></em>

Explanation:

Following the Paleozoic Era, the Mesozoic Era or <em>Age of Conifers</em> began approximately 250 million years ago. This major geological era brought about the ancestors of many of the plant and animal groups still in existence today.

The Mesozoic era is marked by 3 divisions:

  1. the Triassic Period,
  2. the Jurassic Period,
  3. and the Cretaceous Period.

Animals and plants slowly recovered  after the mass extinction in the Permian-Triassic extinction that led to the eradication of most aquatic marine species. They evolved to exploit varying niches in their environment, leading to a boom in terrestrial animals. Over time the planet's increasingly warm climate, abundant in atmospheric oxygen and carbon dioxide, contributed to the growth of diverse megaflora, that rapidly dominated the planet's terrestrial biosphere.

By the end of the <em>Mesozoic Era</em>, in the Cretaceous period, flowering plants (angiosperms) largely replaced the dominant seed ferns of the <em>Triassic</em>, and the conifers, cycads and gymnosperms of the <em>Jurassic</em>.

<em>Varied dispersal  mechanisms in angiosperms co-evolved with the evolution of certain types of fauna. Plants used animal life, including herbivorous reptiles and early mammal-like species to disperse large seeds.</em>

Humans and apes have five fingers they can use to grasp objects. Do you think these are analogous or homologous structures
Ann [662]
Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.
