Answer:Cognitive Behavioral Therapy (CBT)
Explanation:
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.

Air enters the nasal cavity of the respiratory system through the nostril . The nasal cavityis divided by the midline nasal septum Thenasal cavity mucosa has several functions. Its major functions are to warm, moist and clean the incoming air.
The nasal cavity and the mouth meet at the pharynx, or throat, at the back of the nose and mouth. From there, air quickly enters the second part of your respiratory system, the trachea or windpipe. The trachea is a tube that delivers air to the lungs, the third and most important part of your respiratory system.
Vitamin C is needed for the growth and repair of tissues in all parts of your body. It is used to: Form an important protein used to make skin, tendons, ligaments, and blood vessels.
Ice floats on water because it is less dense than water. When water freezes into its solid form, its molecules are able to form more stable hydrogen bonds locking them into positions. ... Most substances in their solid form are more dense than their liquid forms.
