Adenine forms two hydrogen bonds with thymine in DNA while three hydrogen bonds are formed between guanine and cytosine.
Thymine and cytosine are pyrimidines because they have a single ring structure. Adenine and guanine are purines because they have a double ring structure.
The bacteria Can Become Antibiotic resistant over time by adapting or evolving to them so new ones would have to be created to kill them. and this process just keeps repeating over and over.
Antibiotic resistance<span> is a consequence of evolution via natural selection. The</span>antibiotic<span> action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully </span>resistant<span> generation.</span>

Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).
Hope this helps!
