Answer:
I think the answer is option 3
because the products of the process, such as ethanol, contain more energy than does carbon dioxide, the product of aerobic respiration.
Answer:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
Explanation:
An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.
So, an example of this applied to bacteria or viruses could be:
<u>An experiment where an antibiotic is tested against bacteria</u>. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.
C. Both types of reproduction enable genetic information to be passed from parent to offspring.
It doesn't matter if the reproduction is sexual or asexual, because the offspring has the parent(s) dna and genetics either way.
The correct answer is forty-five (45) degrees Fahrenheit.
Raw Shell Eggs are received in 45 degrees fahrenheit refrigerators to prevent the yolks from drying out and to preserve their freshness. Raw Shell Eggs should be handled carefully, since they are fragile and one must also take precautions when handling raw eggs, since they may hold salmonella, but it is less likely to occur.
