Andre45 [30]

Answer:

The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.

Explanation:

In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.

In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.

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.
