The physician can help and guide you in assessing your fitness level and recommend (if necessary) you to professionals that will help in designing your fitness program. The doctor can also help monitor your progress and may assist in adjustments.
Actinomycin is used only in research applications or cancer treatment because it is active against both prokaryotic and eukaryotic cells.
<h3>How does actinomycin work?</h3>
- Actinomycin D inhibits RNA synthesis in both prokaryotic and eukaryotic cells thus blocking transcription.
- Actinomycin was first isolated from <em>Streptomyces antibioticus</em>.
- These bind to the DNA at the site of transcription initiation complex and prevent the activity of DNA dependent RNA polymerase.
- By blocking the metabolic machinery of cells (RNA synthesis), actinomycin prevents the growth of cells. Therefore used in cancer treatment to prevent uncontrolled proliferation of cells.
- As it can also act on eukaryotic cells so it is not used as an antimicrobial drug as it can harm the cells of our body.
- However it can be used in research to prevent microbial growth in petri plates.

Answer:
B. Conduct the experiment.
Explanation:
The scientific method is a series of steps that researchers follow when they want to answer a specific question (hypothesis). This method consists of observation, question, experimentation, analysis, and generating a conclusion.
In this case, <u>the researcher already came up with a question</u>, which could potentially be: Does X fertilizer affect the growth of plants?
He <u>formulated a hypothesis,</u> for example: If X fertilizer is given to X plant species it will grow faster.
The next step is to <u>test the hypothesis by performing a series of experiments</u>. By applying fertilizer to half the plants and collecting data, the researcher is conducting the experiment that will be able to determine whether the results agree with his/her hypothesis.
Based on these results, the researcher will be able to <u>form a conclusion</u>.
