The presence of a large population of _____________ indicates water depleted of oxygen and a high level of organic pollution.
blondinia [14]

The presence of a large population of sludgeworms indicates water depleted of oxygen and a high level of organic pollution.

The sludgeworms Tubifex is harvested and sold as tropical fish food since it is common near sewer outlets and serves as a sign of water or organic pollution. Polychaetes are crucial in rearranging the silt on the ocean floor.

Organic contamination happens when too much organic material, such sewage or manure, gets into the water.

There will be more decomposers and sludgeworms in a pond as the organic content accumulates. These decomposers and sludgeworms develop quickly and consume a lot of oxygen as they do so.

Hence, Sludgeworms are a sign of an abundance of oxygen-depleted water and significant levels of organic pollutants.

How does technology limit the future of space exploration? A. Scientists are able to work both with current and future technolog
GREYUIT [131]
The answer is most likely that the answer is B. Because Space is a dangerous place in which you need certain things to explore it. If you want to go to to Jupiter, for example you need lots of Oxygen, fuel, a good rocket, willing people and many more things, but there is a way technology can skip all that. the technology we have now is not capable of doing that though.

Answer:

To plot a graph, you put the independent variable on the y-axis and the dependent on the x-axis. This might sound really hard, but it's not.

A dependent variable is something that is changed by other factors. For example, in this question, the temperature is dependent on the time. You can't change time by temperature, it's impossible. But you CAN change temperature by the more time that goes by. This makes Time independent and Temperature Independent.

You write the graph so that Time (1-10) goes up the side (the y-axis), starting from the bottom left (this point is called the origin). Then you write the Temperature on the bottom, from left to right. The numbers you are given have to have the same amount of points (the little squares you see) in between them, and you have to be able to fit all of the numbers on the graph.

The last step is to plot the points on the graph so they match up. If the time is 1, then you go to where the time says one and move over to the right to where it is the correct temperature. That is where you put your point. You keep doing this until you have all the points plotted and you can connect the dots.
