Explanation:
hope it is helpful
Answer:
Explanation:
: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.

Which phrase indicates a limit to the scientific accuracy of the experiment?
For the study of a particular drug, Marcus proposes an experiment with a particular population. Approximately 200,000 people in the United States take this drug. He started out with a sample size of 300 people. First, he conducts research on the medical history of the people in his study. He collects the information using reliable sources. He decides to repeat the experiment using a larger sample size.

Answer:
2) 6) 3) 4)
Explanation:
The following factors will affect the current oxygen and carbon dioxide levels.
Burning fossil fuels increases the output of CO2 outside of organisms that perform cellular respiration-CO2 is a green house gas and is a cause of global warming. burning fossil fuels will increase CO2 in the atmosphere which cannot be balanced by the natural sinks like forests and oceans.Deforestation reduces the number of photosynthetic organisms able to produce oxygen and consume carbon dioxide. Deforestation causes habitat loss and hence a large amount of tree cover is lost which will reduce the amount of oxygen generated and CO2 absorbed.When land is deforested for agriculture, the photosynthetic productivity of crops is not equivalent to the forests being replaced. This is so because forests have large trees and plants which have a greater photosynthesis capacity however new crops which are small and are removed annually are not able to compensate for the loss of large forest trees.learn more about oxygen and carbon dioxide levels here:

Summation that results from the cumulative effect of multiple synapses at multiple places on the neuron is designated.
Summation that results from the cumulative effect of multiple synapses at multiple places on the neuron is designated spatial summation.
A strategy for generating an action potential in a neuron using input from several presynaptic cells is called spatial summation. It is the algebraic addition of potentials from various input regions, typically dendrites.This process, known as spatial summation, occurs when inputs from several neurons combine to cause an action potential. These potentials, which are often from dendrites, are combined to produce the spatial summation.The likelihood that a potential will reach the threshold level required to trigger an action potential increases with the amount of excitatory postsynaptic potentials. Similar to this, the likelihood of attaining the threshold potential to trigger an action potential decreases as the number of inhibitory postsynaptic potentials increases.

Clades, which are collections of organisms made up of an ancestor species and its offspring, are also identified through cladistics.
A cladogram only displays one probable phylogeny for a collection of organisms. It can shed light on the process of evolution. A cladogram should not be viewed as a representation of genuine evolutionary processes, though. It may or may not depict what actually occurred. It merely illustrates what might have occurred.

How does water move from the biosphere to the atmosphere in the water cycle
Answer:
The water cycle depicts the ongoing circulation of water inside the Earth and atmosphere. It is a complicated structure with several functions. Water vapor evaporates from liquid water, compresses to create clouds, and falls back to earth as rain and snow.
Explanation:
The water cycle is a cyclical process in which water circulates between the earth's atmosphere, seas, and surface via precipitation, drainage in lakes and rivers, and return to the earth's atmosphere by absorption and evaporation. Throughout respiration, organisms exhale carbon dioxide and water vapor, which evaporates back into the atmosphere.
