The answer to this question is true; contractions during childbirth are an example of positive feedback since they are given to a neurotransmitter known as
IN between the G1 and the G2 phase of the cell cycle the cell's DNA replicates its DNA. The number of chromosomes stays the same, but the amount of DNA molecules duplicates.
Therefore, our cell with 6 chromosomes in the G2 phase has 6 chromosomes and 12 DNA molecules.
Transcribed, RNA
Transcription= converting strands of DNA into single coding strands of RNA
Answer:
In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions
Explanation:
A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.
