Which solution would most likely cause a plant placed in it to become firmer and more rigid?
harina [27]
The appropriate response is hypotonic. Plant cells are encased by an unbending cell divider. At the point when the plant cell is set in a hypotonic arrangement, it takes up water by osmosis and begins to swell, yet the cell divider keeps it from blasting. 
On the off chance that a plant cell is set in a hypertonic arrangement, the plant cell loses water and subsequently turgor weight by plasmolysis: weight declines to the point where the cellular material of the cell peels far from the cell divider, leaving holes between the cell divider and the film and influencing the plant cell to shrivel and fold.

Sometimes new ideas in science come from traditional methods people used in the past. What did researchers learn from terra pret
alina1380 [7]

Answer:

What did researchers learn from terra preta?...  Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.

How is bio-char different from the traditional Amazonian method of creating terra preta?  Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..  

The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Which of the following correctly sorts the organizational levels of a ecosystem form least inclusive to most inclusive
Naddika [18.5K]

Answer:

population - community - ecosystem - biosphere

Explanation:

<em>The correctly sorted level of organization of an ecosystem from the least inclusive to the most inclusive would be from population to community to ecosystem and finally to biosphere.</em>

A population consists of a group of organism of the same species living in a particular area at a particular time and capable of interbreeding to produce fertile progeny.

A community represents different population of organisms that are interacting with one another. Several populations make up a community.

An ecosystem consists of different communities of organisms that are interacting with themselves and the non living component of the environment.

A biosphere consists of all regions of the earth where living organisms can be found. It consists of different ecosystems that make up the earth.

<u>Hence, the population is least inclusive, followed by the community, then the ecosystem and finally the biosphere.</u>
