The answer is C: because growth at 37°C would be ideal for revealing bacteria that are human pathogens. 37°C is equivalent to 98.6°F, the normal body temperature for humans. If bacteria are reproducing at this temperature in a petri dish, they are also most likely reproducing in the body.
Cultures are made so doctors can be sure a person is sick with a specific bacteria often in order to make sure they are taking the right medication to get better. Choice A doesn't make sense, because we wouldn't want to kill the bacteria we are trying to study. Bacteria that makes us sick is harmful bacteria and is what we are trying to isolate. Choice B doesn't make sense, because they are only being incubated at one temperature, not a range or variety. Choice D is harder to rule out, but again the doctor wants the bacteria to reproduce so they can be sure that's what is causing the infection, so it wouldn't make sense that we would put the bacteria in a temperature they would not reproduce.
Answer:
"What seasonings make melt the fastest, garlic, sugar, or pepper?"
Explanation:
this can be a good question because it is highly specific and there are no questions as to what your experiment is
explanations for the scientific method:
1. Make an observation- "different conditions affect the melting of ice such as people salting the roads in winter, this caused me to be curious of what other seasonings might possibly have a similar effect to that of the salt."
2. create a Hypothesis- "I hypothesize that garlic will have the most effect on the melting of the ice because like salt its a more savory seasoning while sugar is more sweet and the reaction would be different and pepper has little flavoring to begin with"
3. test your hypothesis- "this can be done using 3 trials in which 3 pieces of ice are laid onto paper towels and seasoned with 1 teaspoon each of each individual flavoring along with one ice cube that will remain unseasoned (this is our control) we shall then set a timer for 2 minutes and see which ice cube is the most melted"
4. draw conclusions- "this will lead you to the result of the experiment, this would be the seasoning that cause the most effect on the melting process of ice"
Answer:
carbon and titanium, hope that helps
Explanation:
Answer:
The correct order would be
Sensory receptors in the arteries detect low oxygen levels.
↓
Sensory neurons generate an impulse.
↓
The central nervous system relays an impulse to certain brain regions.
↓
The brain sends signals through motor neurons.
↓
Isabel's breathing rate increases.
The working of the nervous system can be summarized as:
The receptors receives the stimulus which then send signals to the brain with the help of sensory neurons.
For example, sensory receptors in the arteries detect the low oxygen levels after which sensory neurons send the signals to the brain.
The stimulus or information is processed in a specified region of the brain which then sends the signals to the effector organ via motor neurons.
The action or reaction is generated at the effector site such as an increase in the breathing rate of Isabel in this case.
I believe that elevated serum creatinine levels indicate a kidney disease
