The six steps of the scientific are:
1. State the question
2. Conduct research
3. Create a hypothesis
4. Perform the experiment
5. Analyze the data
6. Conclusion
So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
There are a lot of separation processes. To name a few, these can be distillation, centrifugation, extraction, membrane or sorption process and many other. To know which is the best technique, you should know the property between two substances that have a stark difference. In this case, it is the polarity. Ethyl alcohol is more polar than ethyl ester and less dense. Thus, these two won't mix. So, take advantage of their density difference by decantation or centrifugation.
Answer:
During Glycolysis 2 molecules of NADH are formed.
Explanation:
When the glycolytic intermediate glyceraldehyde-3-phosphate is converted to 1,3-bisphosphoglycerate by the catalytic activity of glyceraldehyde -3-phosphate dehydrogenase at that time 2 molecules of NAD+ undergo reduction to form 2 molecules of NADH.
The so formed NADH enters into the electron transport chain to generate ATP.
Answer:
We typically represent covalent bonds with a dash ( - ) between the atoms. This indicates a single bond. Ex: Cl - Cl
Single bond, double bond, triple bond.
Explanation:
We call it a single covalent bond because the atoms are sharing a single pair of electrons.
