Biology
1 answer:
fomenos3 years ago
3 0

Answer:

the S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. in this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

in S phase, the cell synthesizes a complete copy of the DNA in its nucleus. it also duplicates a microtubule-organizing structure called the centrosome. the centrosomes help separate DNA during M phase.

1. Do these results support the claim that application of the jewelweed is a good treatment for symptoms caused by poison ivy? E
-Dominant- [34]

A claim is an unverified statement or theory which is made about something which may or may not be true.

<h3>Verification of a claim</h3>

For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.

With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.

If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.

Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.
