1) if you were lost at sea and you drank salty seawater, what would you expect to happen to the cells in your body? (shrink, swell, or stay same size )why do you think that?
2) a large-mouth bass is taken from a fresh water lake and transplanted into the river. if the conditions for survival are optimal, would you expect the cells in the fish to shrink, swell, or stay same size why do you think that?
3) if a sea star egg is taken from the ocean and put into elk lake would you expect the egg to shrink ,swell, or stay same size why do you think that?

1) Our body cells would shrink because the excessive assumption of salt (from the salty seawater), would lead us to use and expel the clean/fresh water we already have out of our body (we'd urinate more as our kidneys would try hard to expel the salt, and we'd use more water than usual as our cells would try to dilute the salt); 

2) I would expect the cells in the fish to stay the same size as both waters have a similar environment and saline level;

3) I'd expect it to swell because the ocean is saltier than lakes; it would swell because it would absorb more water than it did its usual environment.

Essential for a scientist to do for credibility

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
