Assume that you are a national official with the power to set policy for controlling environmental mercury pollution (Core Case
Kazeer [188]

Answer:

The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution.  Policy:

  • Ban the incineration of waste
  • Require that coal-burning companies remove mercury from the coal
  • Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
  • Require that products containing mercury be labeled as such.
  • Set up programs that will recycle batteries and mercury-filled products.
  • Set up education programs that will help inform people about mercury pollution.

This policy works by addressing the ways to prevent and control mercury pollution.

Three problems that could result from implementing this policy:

  • Backlash from coal-burning companies.
  • It could take a while before we completely shift away from using coal.
  • Some of the programs that can be set up in this policy can be too expensive to set up and maintain.

HELP PLEASE!!!!!!

Answer:

They probably use aerobic respiration.

Explanation:

A travel distance of 11.500 kilometers in 9 days covered by flying surely requires a lot of energy.

  • If cells are fermenting, the ATP (energy) they generate only comes from glycolysis, which produces 2 ATP molecules.

  • If they are using aerobic respiration, glucose is completely oxidized to CO₂ through glycolysis and the Citric Acid Cycle, and the electrons enter the electron transport chain to finally reduce oxygen into water. In the complete process, up to 36 ATP molecules are produced.

In sum, aerobic respiration is much more efficient to generate energy than fermentation, so it's probably the main metabolism of the flight muscles in bar-tailed godwits.

Phantasy [73]

In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period
Maurinko [17]

Answer:

Eventually, the environment will be unable to support the production of wildebeests, this will cause there to be a loss of vegitation that then causes a food shortage, and then the wildebeests will starve.  

Explanation:

It's a very unhappy process, but those herds who don't migrate to another pasture will starve and die. The death will depopulate the savanna and give the fields some time for regrowth and the cycle will begin again.

Hope this helps! :)
