How can osmosis preserve food?
by packing food with a lot of salt, osmosis is being used to keep bacteria out of the food. If bacteria land on food with a high salt content, then the salt will suck moisture out of the bacteria via osmosis and the bacteria will die. This is not true for halophiles (bacteria that tend to enjoy being in high salt content), but it is true for many bacteria. This is why, before a good understanding of micro-organisms was developed, people noticed that food could be preserved with salt and this was known as "curing" the food.

A water plant placed in bright light gives off bubbles A student notes that placing the light at different distances from the plant causes the rate of bubbling to vary The student decides to design?
The student could design an experiment to investigate the effect of light intensity on the rate of bubbling in the water plant. By placing the light at different distances and measuring the rate of bubbling, the student can determine how light intensity influences the plant's photosynthetic activity. This experiment can help demonstrate the relationship between light intensity and the plant's ability to produce oxygen through photosynthesis.
When performing an advanced filter you specify conditions by placing the criteria in the same row in Excel?
They can be in the same row, but sometimes there are multiple criteria, so they could be in more than one row. Say you had a list of department and there were two different departments that you wanted to list data from, the criteria would have each of the two departments you wanted on a different row in one column under the department field heading.

Which test involves placing samples of an unknown bacterium in saline adding different antisera and checking for clumping?
The test you are referring to is called the slide agglutination test. In this test, samples of an unknown bacterium are mixed with different types of antibodies (antisera) and observed under a microscope. If the antibodies react with the bacteria, clumps or aggregates will form, indicating a positive result.
