What is an example of an idependent variable?
Temperature is typically an independent variable used a lot of experiments. Say, for example, you are trying to see how temperature affects the growth rate of bacteria. You would know the values of temperature being used in the experiment because you are either increasing the temperature or decreasing it. The growth rate of the bacteria would be dependent on the temperature because increases and decreases in temperature could affect growth rate. In essence, the independent variable is typically the component you control in an experiment.
What is an organism that shows exponential growth?
Bacteria.
What does bacteria require for growth and replication?
The environment for which bacteria can grow must have the right environmental conditions. In addition, bacteria require nutrients such as nitrogen and minerals to use for metabolism
Fight invading bacteria by either slowing their multiplication or destroying them.?
Antibiotics.
Why is exponential growth seen as a bad thing?
Exponential growth is not nescecarily a bad thing - it much depends on what is exponentially growing. A common formula for exponential growth is: a * b^x b is you initial value, a is the factor and x is the amount of times you must multiply a with itself. A common example of 'bad' exponential growth is growth of bacteria or spread of flu. Let's assume you have a collony of 1000.000 bacteria (estimated). You have studied them and found that they effectively double their numbers every hour. b would be 1000.000. a would be 2 and x would be the amount of hours after the experiment was started (+1 because 1 would equal the time the experiment was started). The formula is then: 1.000.000*2^x When you come back after an hour, their numbers would then be 2.000.000. 2 hours after the experiment was started, their numbers would be 4.000.000 and 3 hours after it was started there would be 8.000.000. That's an example of bad exponential growth. The same can be done with flu infections. You know there are 1.000 infected people and as you don't know where any of them are, you can estimate that they'll (on average) infect 3 people every day. So the formula is 1.000*3^x where x is the number of days After 1 day there would be 3000 infected. after 2 days there would be 9.000 and after 3 days 27.000 would be infected. It's a good thing that in reality, these models are flawed. Other factors would count also and make the growth stop itself at some point - for example the bacteria would die when they ran out of food and the infected people would get well and stop infecting others after a few days. I hope this was the answer you were looking for, if not then please specify it more.
What factors do you think will inhibit the growth of the bacteria in a Lima bean and water experiment?
pH of water, chemicals in water, and temperature
Can bacteria grow in Vaseline?
No, bacteria cannot grow in Vaseline because it lacks the water and nutrients necessary for bacterial growth. Vaseline is a petroleum jelly that creates a barrier on the skin and does not support microbial growth.
What experiment might use temperature as a measurement?
An experiment measuring the effect of temperature on the rate of chemical reactions or the growth of plants could utilize temperature as a measurement. By adjusting the temperature and observing changes in the reaction rate or plant growth, researchers can determine the impact of temperature on these processes.
Is there an experiment that can show bacteria?
Yes, you can conduct a simple experiment using agar plates to show the presence of bacteria. You can swab a surface or sample, streak it onto an agar plate, incubate it for a few days, and observe the growth of bacterial colonies. This will demonstrate the presence of bacteria through visible growth on the agar plate.
How does soda affect the growth of bacteria in agar?
Soda contains sugar that can serve as a food source for bacteria, promoting their growth on agar plates. The acidity of soda can also create an environment that some bacteria thrive in, leading to increased growth compared to plates without soda. Overall, soda can potentially enhance the growth of bacteria on agar plates.
How sound effect bacterial growth?
Bacterial growth can be influenced by various factors, including temperature, pH, available nutrients, and oxygen levels. Changes in any of these factors can either promote or inhibit bacterial growth. For example, warm temperatures and nutrient-rich environments can support rapid bacterial growth, while extreme pH levels or lack of oxygen can slow down or stop growth.
Miss Addie is doing an experiment with her chemistry class period of 3000 bacteria, with a growth constant k=2.8 per hour, are present at The beginning of the experiment, in how many hours Will there be 15,000 bacteria?
16
You are doing an experiment on bacteria on the petri dishes your classroom is about 60 degrees Fahrenheit and its been 2 days already your science project is due in 3 days Will the medium bacteria gro?
The growth of bacteria is influenced by temperature. With a temperature of 60 degrees Fahrenheit, the growth of bacteria may be slower compared to warmer temperatures. It is possible for bacteria to grow in such conditions but at a slower rate than if the temperature were more conducive for growth.

How can the growth of microorganism measured?
1_A spectrophotometer is used to determine turbidity by measuring the amount of light that passes through a suspension of cells. 2_An indirect way of estimating bacterial numbers is measuring the metabolic activity of the population (for example, acid production or oxygen consumption). 3_For filamentous organisms such as fungi, measuring dry weight is a convenient method of growth measurement.
What are some techniques to measuring plant growth?
There are a few techniques to measuring plant growth. These include: measuring fresh weight, measuring dry weight, root mass, root shoot ratio. The Science Buddies website shows how one can measure plant growth using these techniques.
What effect does Mercurochrome have on bacteria?
Mercurochrome acts as an antiseptic that can inhibit the growth of bacteria by disrupting their cell membranes and interfering with their metabolic processes. This can lead to the death of the bacteria and ultimately help in preventing infection. However, it is important to note that the use of Mercurochrome has been limited due to concerns about its mercury content.
