Answer:

Bacteria Evolution

This process is called Endosymbiosis.

Explanation:

Symbiosis is a relationship in which organisms from two separate species live in a close, dependent relationship. Endosymbiosis (note that endo means within) is a specific type of symbiosis where one organism lives inside the other.

This causes bacteria, mitochondria, and chloroplasts to be similar in size. Bacteria also have DNA and ribosomes similar to those of mitochondria and chloroplasts.

Based on this and other evidence, scientists think host cells and bacteria formed endosymbiotic relationships long ago, when individual host cells took in aerobic (oxygen-using) and photosynthetic bacteria but did not destroy them. Through millions of years of evolution, the aerobic bacteria became mitochondria and the photosynthetic bacteria became chloroplasts.

Which is a common characteristic of extrusive igneous rock?
Thepotemich [5.8K]

Answer:

Extrusive igneous rock is formed by the crystallization of magma release after volcanic eruption at the Earth surface. They are characterized by fine grained textures because of rapid cooling they do not form large crystals. Extrusive rocks  with fine grained textures are called aphanitic rocks. The most common extrusive igneous rock is basalt. Other examples include rhyolite, andesite and obsidian. Extrusive igneous rocks erupt quickly and they form small crystals. Some of these rocks cools slowly that they form glass. These rocks includes andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria and tuff.  

The common characteristic of extrusive igneous rock is the b. forms crystals

Rapid cooling of magma produces small crystal rocks.

Anastasy [175]

2 geological features of Florida state making it fragile is the Everglades and its bio-diverse nature.

Explanation:

The Florida state is one of three Everglades in the world to be marked as such due to its tendency of being in drought condition all the time due its draining capacity and location in its southernmost parts.

The other environmental condition which the state faces, is the bio-diverse nature of the state. It has endangered species population of cougar.

What is it about a person that could cause ordinarily beneficial traits to become so self-defeating?.
Gala2k [10]

You may have feelings of inadequacy when you can't have—or give your children—the kind of life that others seem to have. All of these situations and challenges can lead to stress, which in turn lead to the development of Self Defeating Behaviors (SBD).

<h3>What is  beneficial traits?</h3>
  • Beneficial traits are extremely varied and may contain anything from protective coloration to the ability to operate a new food source, to a change in size or constitution that might be useful in a certain environment.
  • Over time, these favorable traits become more common in the residents. Through this process of natural preference, favorable characteristics are transmitted through generations. Natural preference can lead to speciation, where one species gives rise to a new and distinctly different species.
  • The artificial section is the identification by humans of seductive traits in factories and animals, and the steps taken to enhance and memorialize those traits in future years.

To learn more about beneficial traits, refer to:
