What might be Hershey and Chase have concluded if they had found 32P and 35S in bacterial cells?
They might have concluded that both protein and DNA transmitted hereditary material. The 32P was a radioisotope in DNA, and the 35S was a radioisotope in proteins. They were used to track the DNA and proteins to see if they were injected by a virus into a bacterium.
What changes might bacteria cause in urine?
Bacteria in the urinary tract could cause blood or elevated protein in the urine. Urine may also contain white blood cells which came to fight the infection.
How might the physical differences between gram positive and gram negative bacterica contribute to differences in chemical resistances?
Gram positive bacteria do not contain a protein sheath over their peptidoglycan membrane layer. Because of this, a gram negative bacteria's membrane (which contains a protein coating over the peptidoglycan) is more resistant to being penetrated by chemicals.
What is a characteristic of chloroplasts that suggests that they might have evolved from free-living bacteria?
Photosynethic bacteria are likely involved.
What branch of chemistry studies the boiling point of a liquid?
Just about any branch might look at boiling points, but it's in the area that a Physical Chemist might follow.

Why do people boil drinking water after a flood?
If they are worried about it being unhealthy, they might do that. Boiling it kills a lot of things that can make you sick.
Why should a casserole with ground beef be cooked to 150?
The reason why is to kill the bacteria & prevent salmonella
Does boiling affect any viruses that might be present?
to a degree but you can have more temperature resistant spores Yes, because virus' cannot survive beyond certain temperatures.

Bacteria in the urinary tract could cause blood or elevated protein in the urine. Urine may also contain white blood cells which came to fight the infection.
What may happen to the boiling point of a substance if there are impurities present. Explain in terms of the nature of impurities.?
it might decrease or increase depends on the impurities added.:D
How is nitrogen part of the biosphere?
It's continuously processed in the nitrogen cycle. In broad outline nitrogen in the atmosphere is fixed by bacteria so that it's available to plants making protein. This protein is consumed by animals and plants or returned to the atmosphere as methane. The plant nitrogen is converted to animal protein which is eventually returned to the atmosphere by bacteria. For more detail you might wish to refer to information on wikipedia.
What might happen if pepsin doesn't work properly?
Pepsin is the proteolytic enzyme of the stomach which converts proteins to peptones and dipeptides.. if this enzyme is not present, protein digestion cannot be completed... hence our body will suffer from protein deficiency..

59 33 The insertion of a human DNA fragment into a bacterial cell might make it possible for what?
1 for bacterial cell to produce a human protein

If the walls of the capillary cluster in a nephron were damaged or broken what substance might you expect to find in urine that is not normally present Explain Please?
the substance might you expect to is dead blood cells
