Did growth happen at a different level in agar deep?
The agar deep stab is an experiment to determine the affect that oxygen has on a culture. If growth is found only at the top, this indicates an obligate aerobe. If growth is found at the bottom only, then it would be a obligate anaerobe. If growth is found all throughout the stab, this would indicate a facultative anaerobe. Obligate aerobes require oxygen to survive. Obligate anaerobes cannot survive with oxygen present. Facultative anaerobes can survive in both cases but usually prefer aerobic conditions.
What are the surface colonies on a pour plate larger than those within the medium?
The surface colonies on a pour plate larger than those within the medium especially aerobic bacteria within the medium would be a restriction of growth. The restriction of growth would be due to the lack of oxygen.
When would expect to see a species go through a logistic growth pattern?
A logistic growth pattern occurs when the population reaches its carrying capacity, at which point the population growth is zero.
If over a period of 10 years a population has a logistic growth rate you would expect to see?
a stable equilibrium phase
Which would not change a potted plants growth?
lack of water and fertilizer would not change the growth

Which type of organism aerobe anaerobe microaerophile facultative anaerobe would most likely be affected negatively by the use of old media?
I would think an aerobic organism would do the worst in an oxygen poor media, which would be one of the results of having an older media sitting around.
Where would you expect to see growth of a strict aerobe anaerobe microphile and facultative anaerobe in the fluid thioglycollate medium?
The sodium thioglycollate in the broth creates a redox potential in the tube, with higher levels of oxygen at the top of the tube, and a complete absence of oxygen at the bottom of the tube.Fluid thioglycollate broth also typically contains a redox potential indicator such resazurin, which produces a pink color in an oxidized environment. As with the BHI media, organisms will only be able to grow where their oxygen requirements are met, and will localize to the area(s) of their oxygen requirements in the fluid thioglycollate broth.Obligate aerobes will grown on or very close to the top (high oxygen). Obligate anaerobes will only grow on the bottom (no oxygen). Facultative anaerobes will grow throughout but more on top. Microaerophiles will be found in a band where only a small amount of oxygen is found. They would be close to but not on the top.
How microbes are classified based on their oxygen preferences?
On the basis of oxygen requirement microorganisms are classified asAerobes: organisms that use molecular oxygen as electron acceptor.Anaerobes: organisms that use some molecule other than molecular oxygen as electron acceptor.Facultative organisms : organisms that can use either molecular oxygen or some other chemical compound as electron acceptor.
How will the arrangement of thre lactococcus lactis in broth differ from the arrangement in a slant culture?
In the slant culture, the bacterial growth is even to spreading to irregular. On the other hand, in broth culture, the growth ranges from sedimentation at the bottom, to turbid growth to pellicle growth.
Where would you expect to find in a country with zero population growth?
In a country with zero population growth, you would expect to find a stable population size where the number of births equals the number of deaths. This would mean the population is not increasing or decreasing over time.
What growth you are expecting on your salary?
I would expect 30% of my current salary.
What are the surface colonies on a pour plate larger than those within the medium?
The surface colonies on a pour plate larger than those within the medium especially aerobic bacteria within the medium would be a restriction of growth. The restriction of growth would be due to the lack of oxygen.
Would you expect growth of crop in a farm or in a topographic level?
On leveled land~!
A bacteium would be killed by exposing it to oxygen would be a?
A bacterium to which oxygen is cytotoxic is known as an obligate anaerobe.
what growth results would you expect under white lights?
You can expect normal plant growth. The white light is similar to the sun in having all the colors so this can help the plant to grow naturally if there is not a lot of sun.
What would you expect to happen to the vaginal microbiota of a patient with a defect in estrogen production?
Growth of opportunistic pathogens would increase.
