What is the type of sunflower, and how fast does it use photosythesis?
Answer:
The tiles can be arranged as follows:
- make an observation
- ask questions
- construct a hypothesis
- test the hypothesis
- analyze the results and make conclusions
- communicate the result
Explanation
A scientific investigation begins with certain observations. By seeing these observations, a question is made. To answer the question, a hypothesis is generated. A hypothesis is a tentative statement that can either be stated s correct or wrong. To test the hypothesis, experiments are made and results are deduced from the experiments. Based on these results, a hypothesis can be proved as correct or wrong. These results are then communicated to check for their authenticity.
Given what we know, we can confirm that if a cancer medicine wishes to stop cellular division, it must target the Centrioles of a cell.
<h3>What are the Centrioles of a cell?</h3>
- The centrioles are cylinder-shaped organelles made up of microtubules.
- Their function is to organize the contents of the cell before cellular division.
- This is done to ensure that once the cell divides, its contents are split evenly to each daughter cell.
- They also play a role in initiating the cellular division process.
Therefore, given the role of the centrioles in organizing the contents of the cell for cellular division, as well as initiating the first part of cell division, we can confirm that in order for a cancer medicine to stop cell division, it must target the centrioles.

Repressor slows down transcription.
RNA Polymerase enzyme transcribes mRNA from DNA.
Explanation:
Promoters are the 100 to 900 bps long sequence of DNA, that helps in the initiation of transcription. The transcription gets slow down as repressor bind to the promoter region hampering the attachment of RNA Polymerase enzyme which is responsible for transcription.
The process of transcription is the conversion of DNA into mRNA as told in the central dogma of molecular biology. Enzyme responsible for transcription is RNA polymerase. It is the first phase of gene expression, where DNA strand is copied into mRNA called a primary transcript.
