A chemosynthetic bacteria is a producer. Chemosynthetic bacteria produce energy by using chemical reactions similar to photosynthesis but without the light as a catalyst. A chemosynthetic bacteria can produce organic molecules (i.e. glucose) from inorganic molecules just like photosynthetic organisms.
<span>These are:
1. <u>Number of microbes</u>: if there is a lot of microbes, then more time is needed to kill all of them.
2. <u>Characteristics of microbes</u>: some microbes have resistance genes, so they will not react to agents they are resistant to; some microbes have protective structures so treatment will be inhibited.
3. <u>Time of exposure</u>: different agents will need different time to kill microbes.
4. <u>Environment</u>: the effect of temperature, pH, organics both on microbes and agents.</span>
Hey there, thanks for asking a question here on Brainly.
The molecules in a
solid cannot change position because the bonds are so powerful. Look at the image below to see a good example of what I mean.

Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.
Explanation:
In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.
It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.
For the other options:
- <u><em>The amount of noise</em></u><em>. This can modified by the use or not of headphones and is the independent variable, subject to modification.</em>
- <u><em>The type of music the employees listen to while they work</em></u><em>. Does not represent dependent or independent variable.</em>
- <u><em>The amount of training employees need</em></u><em>. It is not the variable being studied.</em>
