AysviL [449]

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.

Which of the following macromolecules enter the nucleus of a eukaryotic cell through pores in the nuclear membrane? a. rRNAb. ri
Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.
