While observing some ants, a group of German scientists noticed that the ants had an excellent sense of distance. Wondering how this was possible, they decided to perform an experiment.
First, the scientists taught ants to retrieve food from a feeder placed near the ants' home. Then, they removed the lower portion of
some of the ants' legs to make them shorter. They also attached tiny stilts to some of the other ants' legs to make them longer.
Finally, the scientists watched the altered ants attempt to retrieve food from the feeder.
After several trials, the scientists found that the ants with shortened legs walked toward the feeder but stopped short of it. On the
other hand, the ants with lengthened legs walked past the feeder.
Which of the following conclusions can be made given this information?

the titanic would be the correct answer

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
