Explanation:
Medical oxygen is used to: ... restore tissue oxygen tension by improving oxygen availability in a wide range of conditions such as COPD, cyanosis, shock, severe hemorrhage, carbon monoxide poisoning, major trauma, cardiac/respiratory arrest. aid resuscitation.
this is you're answer please give me thanks
Answer:
In cells, oxygen is needed for aerobic respiration, which allows for the extraction of energy from ingested foods. Thus supplemental oxygen at home and in hospitals is vital for those with breathing disorders such as emphysema.
Compressed oxygen tanks are used by mountaineers at high elevations to counteract the decreased O2 pressure at these altitudes.
Supplemental oxygen is needed for surgical patients intentionally rendered paralyzed for medical procedures, in which "heart-lung machines" keep their vital functions going.
Oxygen can be used as a sterilizing agent to kill certain anaerobic bacteria that are killed by sufficient exposure to the gas.
Industrial Uses of Oxygen:
Oxygen is needed for the reaction that converts carbon to carbon dioxide gas in steel working, which takes place under high temperatures in a blast furnace. The carbon dioxide produced allows for the reduction of iron oxides into more pure iron compounds.
Oxygen is used in other applications involving metal and requiring high temperatures, such as welding torches.
Aerospace Uses of Oxygen:
In liquid form, oxygen is used widely as an oxidizing agent for use in missiles and rockets, where it reacts with liquid hydrogen to produce the terrific thrust needed for take-off. Astronaut spacesuits include a nearly pure form of oxygen.
Oxygen is used to degrade hydrocarbon compounds, which are broken apart by heating them. This is used to create combustion that usually liberates water and carbon dioxide, but can also produce the hydrocarbons acetylene, propylene and ethylene.
Oxygen is used in sewage-treatment and water-purification plants. It is forced through water to increase the production of bacteria that metabolize waste products in the water.
Oxygen gas (O2) is needed to produce energy in things not linked to an electrical supply of their own, such as generators and vehicles (e.g., ships, airplanes and cars).

How does a magnifying glass make an object look bigger and closer?
Answer:
Any converging lens that has a small focal length (several centimeters) can be used as a magnifying glass. The observed object is placed in front of the magnifying glass so that it is located between the lens and the focus (closer to the focus).
Explanation:
It consists of only one condenser lens of small life (a few centimeters).
The observed object is placed between the magnifying glass and its focus (closer to the focus)
The observer sees an upright and enlarged figure of the object.
In order to like clear video ("sharpen"), the magnifier zooms in or out of the subject.
When the character is most clearly seen, we can find ourselves on a given high species.
For a man with normal eyesight, it is about 25 cm.

Explanation:
Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
an increase in food availability
an increase in pollution
a decrease in tuna fishing
a decrease in tuna predators
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
Other options, such as an increase in food availability, a decrease in tuna fishing or a decrease in tuna predators, are environmental factors that contribute to increased genetic variability.Answer:

What do we call the changing in magnetism as we move out from the center of a mid-ocean ridge?
Plate tectonic systems
Continental creep
Faulty ground flow
Magnetic reversal
Answer:
Continental Creep
Explanation:
The definition of Continental Creep is:
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.

Worldwide, renewable energy is the fastest growing source of energy yet it only
provides 10% of our total energy. Explain two positives and two negatives associated
with renewable resources.
Answer with Explanation:
Positive
1. They don't create too much pollution, which makes them "clean."
It allows us to have a clean air because there's no need of burning them just like the fossil fuels (non-renewable).2. They don't cost too much to run.
The supply of these resources doesn't cost anything at all. For example, solar energy relies on the heat of the sun. The sun's heat is definitely free and can be found in most sunny places.Negative
1. Setting up is expensive.
An example of this is the "wind turbine" that costs millions of dollars in order to set up.2. The output is affected by many factors.
Depending on the kind of renewable resource, most of these are affected by many factors. For example, wind turbines rely on wind's blowing while the hydroelectric powers can be affected by drought.Process used when it is time for an
entire organism to reproduce
Answer: reproduction
Explanation: the process by which an organism produces its offspring is called reproduction.
The process used when it is time for an entire organism to reproduce is called MEIOSIS.
Meiosis is a type of reductional cell division by which a parental cell divides to produce four daughter cells having half of the genetic material (DNA) compared to the parent cell.Meiosis is used by organisms with a sexual mode of reproduction to produce new organisms by a process called fertilization, which involves the fusion of two meiotic cells, one from each parent.Germinal (sex) cells reproduce by meiosis, while somatic (body) cells reproduce by mitosis.In conclusion, the process used when it is time for an entire organism to reproduce is called MEIOSIS.

PLEASE MARK ME AS A BRAINLIST!!
Answer;
shortly:-The main differences between prokaryotic and eukaryotic cells are the presence of a nucleus, the size and complexity of the ribosomes, how the cells reproduce and the presence of a cell wall. Ribosomes: In eukaryotic cells, the ribosomes are bigger, more complex and bound by a membrane
but you need more explanation:-
Eukaryotic organisms are made out of cells that possess membrane-bound organelles and a membrane-bound nucleus. The genetic material of eukaryotic organisms is found within the nucleus of the cell and chromosomes are how the DNA is organized within the nucleus. Eukaryotic cells comprise both single-celled and multicellular forms of life. Eukaryotes compose the bodies of all protists, fungi, plants, and animals.
Eukaryotic cells display an impressive amount of diversity, and they are capable of being many different shapes and sizes. The structure of a eukaryotic cell is tied closely to its function. For example, the epithelial cells that make up the human body are usually divided into three different types: squamous, cuboidal, and columnar. Each of these different cell types has a different form that enables it to carry out its respective functionsEukaryotic cells may have the following parts:
Cell wall (only plant cells)
Plasma membrane
Nucleolus
Nucleus
Chromosomes
Vesicles
Golgi apparatus
Ribosomes
Endoplasmic reticulum
Cytoplasm (and cytoskeleton)
Lysosomes
Mitochondria
Centrioles
Chloroplasts (only plant cells)
Prokaryotic cells are almost always much smaller than eukaryotic cells. The size of a prokaryotic cell is usually around 1 µm, while the size of animal cells and plant cells are usually between 10 to 100 µm. Because eukaryotic cells are much larger than prokaryotic cells, they have evolved special methods of transporting substances around the cell that bacteria don’t have.

Each of these different cell types has a different form that enables it to carry out its respective functions.
The distinction between eukaryotes and prokaryotes is based upon two theories regarding the role of cells in biology. Cell theory states that all living things are made out of cells, and biogenesis theory proposes that all living cells came from other existing cells, so cells cannot spontaneously arise from non-living things (abiogenesis). For cells to comprise all the life we see on Earth they must be able to organize proteins and other chemical compounds. Individual cells are capable of keeping chemical processes isolated and compartmentalized so one chemical process doesn’t interfere with another chemical process, which runs the risk of disrupting the delicate chemical balance of the cell and leading to cell death.
“A cell is regarded as the true biological atom.” — George Henry Lewes
To keep the chemical processes within a cell isolated and organized, cell components stay enclosed within a membrane that serves as the barrier between the interior of the cell and the cell’s environment. The membrane of a cell is selectively permeable, meaning that the cell will allow some chemical compounds into the cell and not others. The membrane of the cell is made out of a phospholipid bilayer, two groups of lipids arrayed in layers and facing opposite directions. Smaller compounds can penetrate the phospholipid bilayer, but larger compounds must enter the cell using a pore in the cell membrane.
The cell membrane has various methods of regulating how chemicals move in and out of the cell. Diffusion refers to the tendency of molecules at high concentrations to distribute out to areas of lower concentration until the concentrations across the two areas equalize. Osmosis is similar to diffusion, but it refers to the movement of a solvent across a boundary instead of a solute. This helps to equalize a solute that can’t move through a boundary. Selective transport, the movement of molecules within the cell, is handled by both membrane pumps and membrane channels.
