The deepest parts of the ocean are hostile to life. A barren stretch of sea floor recently experienced an earthquake that opened up a
hydrothermal vent. This vent provides heat and nutrients. Over time, the area became filled with various deep-sea life forms. What kind of
ecological activity is this?
This is a form of ?
Answer:
Hydrothermal
Explanation:
Deep hydrothermal vents are located in areas with high tectonic activity, including the edges of tectonic plates, undersea mountain ranges and seamounts, and mid-ocean ridges. The water escaping from deep hydrothermal vents may be clear-ish and have low concentrations of minerals or it may be white or black and be characterized by high concentrations of minerals. These so-called white or black smokers look like chimneys, constantly blowing ‘smoke’ up from the sea floor. Minerals escaping from these vents usually include hydrogen sulfide or some other sulfur compound.
The deep-sea environment where these vents occur is completely dark, and photosynthesis (=the conversion of carbon dioxide into sugar using sunlight) is impossible. Photosynthesis is the process by which plants and algae form the bottom of the food web, wherever there is sunlight. In the deep sea, most of the food must sink from the sunlit sea surface; however, as it sinks, it is eaten by all sorts of organisms. Very little food makes it to the deep sea floor. At deep hydrothermal vents, though, specialized bacteria can convert the sulfur compounds and heat into food and energy. As these bacteria multiply, they form thick mats on which animals can graze. In some cases, they form symbiotic relationships with animals, (e.g., giant tube worms) and live in the animals’ tissues, creating energy in return for receiving protection from predators. These specialized bacteria form the bottom of the deep hydrothermal vent food web, and many animals rely on their presence for survival, including deep-sea mussels, giant tube worms, yeti crabs, and many other invertebrates and fishes.
A similar deep-sea ecosystem is called the cold seep (or cold vent), where mineral- or methane-rich water seeps from the seafloor. Cold seeps do not require high tectonic activity and may be located more sporadically across the deep sea. Again, specialized bacteria utilize the high density of sulfur or methane compounds to create food/energy, again forming the bottom of a complex food web.
Some scientists hypothesize that the first life on Earth may have originated at deep hydrothermal vents.

which of the following bacterial names gives information about its cellular morphology?
please helpppp:(
Answer:
Coccoid bacteria
Explanation:
Bacterial genus names like Bacillus and cocci indicate information about their morphology.
What are scientific names?A widely used and formal system of naming a species is called binomial nomenclature or scientific nomenclature. This nomenclature is composed of two names. Both of them are derived from Latin.
However, they are sometimes derived from other languages as well. It is simply also called a binomial name or a scientific name.
The generic name is the initial part of the name and it highlights the genus of the organism. The second part is the specific name. It identifies the exact species of which the organism actually is within that species.
Also, there are some specific and certain rules that need to be followed in the binomial nomenclature. The first letter of the generic name is always capitalized, but for the specific name, it is not. The entire name needs to be italicized when typed. When handwritten, this is not important.

Explanation:

It is called an Ecotone.
An ecotone can be described as the meeting point of two different biomes. It is usually referred to as a transition zone.
An ecotone is characterized by mixed characteristics or intermediate conditions that are quite different from the two adjoining biomes.
An example of an ecotone is the mangrove forest. The mangrove forest is an integration of terrestrial and marine ecosystem. Other examples of an ecotone include grassland, marshland, among others.
Therefore, the area of land where two major biomes meet and interact is called an ecotone.

II. How has the geology of an area affected its climate?
III: Which compounds do people prefer to use in their fertilizer?
Options:
A. I and III

D. II only
Science is the field that uses the research methodology to search for answers. How the geology of an area affects its climate can be answered by science. Thus, option D is correct.
What is the relation between geology and climate?Geology is the study of the evolution, structures, and resources of the earth and its different layers. It analyzes the various factors developed over millions of years. It is also used to study the regions that affect the climate.
Climate geology includes the study and analysis of the areas and the factors that affect the climate of the place. It involves the parameters like carbon dioxide, oxygen, pollution, and natural disasters like volcanic eruptions.
The first question about using solar energy rather than wind energy and the third question about components of fertilizers are opinion-based questions that depend on an individual's preference.
Therefore, option D. only II question can be answered by science.

which two sentences best describe the role of the setting in the story
Answer: Hello There!...................
The setting helps reveal the speaker's joyous attitude.
The setting helps develop the theme of freedom in the story.
Explanation:
Mark me brainest please. Hope this helps. Anna ♥
Explanation:
Setting is one of the elements of a story. It is the context that surrounds the story - be it fiction or non-fiction -, its time and place. It usually takes one of three forms: an outdoor place, such as a forest; a public or private place that has some importance for the characters, such as a house or a park; the cultural and historical background, which helps readers understand what sort of influences that characters were under.
Thus, the setting is a vital element to convey ideas and theme, as well as create the mood and emotional response for readers. The setting can be so important in a narrative that it may become a character in itself. In Edgar Allan Poe's "The Fall of the House of Usher", for example, the house where Usher lives influences him and the narrator. It's as if the house is alive, haunted, driving those who stay in it to madness. Without the proper setting, however, this story wouldn't provoke the same emotional response in readers - fear, suspense etc.
