Sorry its a very long answer-
1.) Failure to maintain the rule of law
The government's repeated failures to bring levels of violent crime under control contributed to an environment which saw people resort to violence without fear of arrest or successful prosecution.
2.) Border control
3.) Corruption
4.) Employment
5.) Education
This has been government's biggest failure and carries much of the blame for the high unemployment levels. It is arguable whether current state education is in its totality any better than that under apartheid. Only 1% of black matriculants achieve a good HG maths pass.
The education system is a good example where policy failures in one area compounded those in another.
6.) Slowing economic growth
7.) Foreign policy
8.) Service delivery
9.) Race relations
The one that isn’t given the treatment is the control because it allow you to compare the result of when you would add music and when there isnt music
Answer:
The statement that can best explain why during the warmer parts of the day, fish are found in deeper waters of a lake is that warmth lowers the oxygen concentration near the surface.
Explanation:
Organisms in any aquatic ecosystem require oxygen to perform their functions and survive. But the availability of dissolved oxygen in water, especially at the surface, can be affected by environmental temperature.
- <em>Warm temperature decreases the dissolution of oxygen in the lake surface water, encouraging fish to move to deeper areas.
</em>
- <em>Lower temperatures increase the dissolution and availability of water at the surface, so fish can be found closer to the surface when the weather is cold.
</em>
This behaviour of dissolution / availability of oxygen at the lake surface can be observed with seasonal changes or with temperature changes between day and night.
