Ecologists alone cannot solve environmental problems. Solving ecological problems involves a blend of ethical, economic, and pol

itical considerations. A perfect example is the decision on whether or not to build the Keystone pipeline from the Alberta tar sands to the American Gulf Coast. Identify at least three considerations in total from both sides that are critical to this debate.

Answer and Explanation:

  • <u>Environmental impact</u>: One of the most discussed topics is that the Keystone XL might be constructed as a shortcut in an area characterized by being a fragile and sensitive ecosystem. This section addition will cause important and harmful environmental impacts in Nebraska’s Sand Hills region.  
  • <u>Environmental impact: </u> Another important impact is that oil extraction from the Alberta oil sands, involves a process that requires far more energy, more water, more fuel, and results in an important carbon dioxide emissions. This extraction is much more damaging than conventional oil and gas extraction.
  • <u>Economic impact</u><u>:</u> This project might generate so many jobs that it is argued to be good for the economy. Most jobs are thought to be temporary in two years lapse of time. But there would also be some permanent jobs.  
  • <u>Economic impact</u><u>:</u> Keystone XL construction might enhance energy security.
  • <u>Economic impact</u>: The project also estimates to contribute in a possitive way to the economy of the United States.

VLD [36.1K]

1. Polymer refers to a lengthened, chain-like molecule comprising repeated units associated end to end.  

2. Ceramic refers to a hard, brittle, corrosion and heat tolerant substance formed by administering a non-metallic mixture of minerals to intense heat.  

3. Thermoset refers to the plastics, which exhibit low elongations and cannot get recycled again.  

4. Thermoplastic refers to the plastics, which exhibit high elongations and can be recycled.  

5. Crystal refers to the solid form originating from the organization of ions, atoms, or molecules in precise patterns of geometry.

Molodets [167]

Answer:

2.glucose move into chamber B faster than fructose

Explanation:  

  • Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.  Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.  

The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.

How does a lyric virus kill the cells that it infects
Aleksandr [31]

Answer:

This may help!

Explanation:

In the lytic cycle, a phage acts like a typical virus: it hijacks its host cell and uses the cell's resources to make lots of new phages, causing the cell to lyse (burst) and die in the process. Entry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium.
