A biologist must make a medium to grow a type of bacteria. The percentage of salt in the medium is given by S=0.01(x^2)(y^2)z , where S is the percentage expressed as a decimal. And where x, y, and z are the amounts in liters of 3 different nutrients mixed together to create the medium. The ideal salt percentage for this type of bacteria is 35.7%. The costs of the x, y, and z nutrient solutions are respectively 10 , 7, and 8 dollars per liter. Determine the minimum cost that can be achieved.
(Round your answers to the nearest 4 decimal places.)

A biologist must make a medium to grow a type of bacteria. The
percentage of salt in the medium is given by S=0.01x2y2zS=0.01x2y2z
, where SS is the percentage expressed as a decimal. And where xx,
yy, and zz are the amounts in liters of 3 different nutrients mixed
together to create the medium. The ideal salt percentage for this
type of bacteria is 34.7%. The costs of the xx, yy, and zz nutrient
solutions are respectively 10 , 4,...

Wild-type E. coli can grow on minimal medium. You have
isolated a mutant strain of E. coli that grows poorly in minimal
medium that contains lactose and arabinose and lacks glucose. In
ONPG-containing minimal medium lacking glucose the mutant strain
produces very low levels of b-galactosidase activity in both the
absence and presence of IPTG. The strain does not grow well when
transformed with a plasmid containing the lacZ and lacY genes. The
strain also does not grow well when...

A biologist claims that a specific type of hamsters live for
longer than, or equal to, 5 years on average. From 2000 hamsters
that she has in her lab, she selects a random sample of 50 hamsters
for testing and recorded that they lived for 4.9 years on
average.
Based published papers in the field, she knows that the standard
deviation of the lifespan of this type of hamsters is 1/3 years.
Help the biologist to conduct a hypothesis test...

A bacteria culture is grown for many generations in a medium in
which the only available nitrogen is the heavy isotope
(15N). The culture is then switched to a medium
containing only 14N for TWO generation of growth; it is
then recultured to a 15N-containing medium for ONE final
generation of growth. The DNA from these bacteria is isolated and
centrifuged to equilibrium in a CsCl density gradient.
(a) Determine the proportion of 15N15N,
15N14N, and 14N14N DNA if the...

when you need the components of the question above to grow a
certain bacteria, and the bacteria grow in closed tubed in a closed
dark, non-shaking incubator that is set at 54C, which definition
correctly applies to these bacteria:
a. photo-heterotroph
b. halophile autotroph
c. heterotrophic thermophile
d. aerobic psychrophile
e. alkaliphilic acidophile
Heterotroph – Yes, the bacteria need glucose but the
overall answer is NO because of the fact that there is no
light
Autotroph: NO, because it needs...
