Answer:
1st Step: Observation
2nd Step: Questioning
3rd Step: Data Collection
4th Step: Data analysis
5th Step: Communication
In the scientific method, the first step is always to make an observation. You can observe anything in your environment, or a phenomena, or behavior.
The next step would be to question. You form a question to find a possible explanation as to why what you had observed occurred. This is also when you make a hypothesis. An educated guess or a proposal that could explain the event.
After you make a hypothesis, you start an experiment where you will collect data. The data you collect would then be analyzed (4th step). From there you build your conclusion to determine whether your hypothesis holds true.
The last step would be communication. You will communicate the results of your method. This allows people to review your data and process, which may be supported or invalidated. Communication is critical in the scientific world because your results could be the basis for further investigation.

Answer:
No
Explanation:
Red blood cells don’t reproduce. They only survive for 120 days in our blood before they are broken down into parts that are then recycled by a special type of white blood cell.
They all need energy, food, and water. If we're talking about animals, then they need oxygen. If we're talking about plants, then they need carbon dioxide
They do not need parents. Some animals don't have parents the moment they are born (eg: sea turtles).
So based on all that, B seems like the best answer
