Nitrogen is key to cellular growth. It is usually acquired from the atmosphere where it is
abundant It must be broken down by nitrogen fixers to be usable It is a central component of
lipids This is false, it is not key to growth Most pathogenic bacteria (to humans) are:
Thermophiles Psychrophiles Hyper Why? (referring to? 11) Because they grow in the same
temperature range as the human body Because they grow in the same pH range as the human
body Because they are the only types of organisms found on earth This category refers to
pathogenic bacteria, harmless bacteria have a different name A cell is dividing by binary fission.
How does it ensure that each daughter cell receives a copy of its chromosomal DNA? It doesn\'t
this is a random process There are enough copies of the chromosomal DNA that this will likely
happen Each copy of the DNA attaches to the cell membrane. As the cell elongates the
chromosomes move apart from one another, ensuring that one copy is in each daughter cell. Each
copy of the DNA attaches to the cell wall as the cell elongates the chromosomes move towards
one another. You go to the dentist to have some work done on your teeth After they learn that
you have recently had open heart surgery they say that they will not work on your teeth unless
you are on antibiotics. Why? They are medical professionals and it is their job to follow up on
your heart surgery They are worried that scrapped off from the patients\' teeth will ultimately
colonize your heart They are worried that plank tome bacteria scrapped from your teeth will
ultimately colonize your heart They know that the antibiotics used during surgery will also kill
the bacteria in the mouth and thus tooth cleaning is unnecessary are usually: Homogeneous
mixtures of bacteria Rare and almost only found in hospitals Heterogeneous mixtures of
microorganisms Easy to physically remove from surfaces (such as river rocks)

10. b. It must be broken by nitrogen fixers to be able to use
11. d.Mesophiles
12. (a) because they grow in the same temeperature
They have optimal grwoth temperatures between 20C to 40C, whereas human body temperature
of 37C makes a perfect environment for their growth..
