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.

is energy lost by catabolism or anabolism?
Explanation:
Anabolism requires energy to grow and build. Catabolism uses energy to break down. These metabolic processes work together in all living organisms to do things like produce energy and repair cells.

Which of the following lists best illustrates the idea of increasing levels of complexity?1) Cells, tissues, organelles, organs, systems.2) Tissues, cells, organs, organelles, systems.3) Organs, organelles, systems, cells, tissues.4) Organelles, cells, tissues, organs, systems.
There exist different levels of organization in nature, which go from the smallest things like atoms, to the most complex systems like ecosystems. In the exposed situation, the correct increasing order is Organelles, cells, tissues, organs, systems.
------------------------------------
According to the composing elements, we can find many different organization levels in nature.
Organelles: These are molecular subcellular structures that carry out one or more specific functions in the cell. Cell: Molecules get grouped in living cellular units that have auto replication capabilities. It is the smallest structural unit capable of functioning by itself. A cell is capable of communicating with other cells. When they receive signals from the exterior, they respond in varying ways. Their membranes delimitate them and protect them, constituting a selectively permeable barrier. Cells There are different cells with different sizes, shapes, and forms.Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera. Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function. Systems: When different units -organs or individuals- get associated and work together, they become a system. By working together stably, these associated units maintain homeostasis.-----------------------------------------

which activity produces an action potential in nerve cells
Answer:
The action potential is an explosion of electrical activity that is created by a depolarizing current. This means that some event (a stimulus) causes the resting potential to move toward 0 mV. When the depolarization reaches about -55 mV a neuron will fire an action potential.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

what is the concept that organisms can only come from other organism called
The concept that organisms can only come from other organisms is called biogenesis.
The concept of biogenesis has to do with the belief that organisms cannot just arise spontaneously from non-living objects or sources, but can only arise from another living organism through the process of reproduction.
Biogenesis is as opposed to abiogenesis. The latter is a concept that opines that organisms can arise spontaneously from non-living sources without any reproduction.

Answer:
The Correct answer is DNA is transcribed into RNA which is translated into protein
Explanation:
The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

explain why air exhaled during exercise contains more carbon dioxide than exhaled at rest
Answer:
In addition, the blood contains some carbon dioxide (a waste product) that is transferred to the air in the lungs, which is then exhaled. The result is that the exhaled air contains less oxygen and more carbon dioxide than the inhaled air.
You will exhale more CO₂ during exercise because the body consumes more glucose and oxygen during exercise than when at rest.
During exercise the body require a lot of energy than usual hence more calories( glucose ) are burnt with oxygen to provide such energy therefore releasing more CO₂ as waste product , therefore you will exhale more CO₂ while exercising.
Hence we conclude that it is because the body consumes more glucose and oxygen during exercise than at rest.
