The answer is B Microscope :)
Because if something goes wrong there can be mutations and cause the rest to the replication to mutate I believe
The two types of limiting factors are Density - dependent and Density independence. <span> Density-dependent limiting determinants depends on the community size; the comprehensive population, the consequential influence a density-dependent limiting agent will ought. Density-independent limiting determinant does not really depend on inhabitants dimension, alternatively they change all populations proportionately. </span>
Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
Radioactive elements are useful for the study of the biological system because of the unique properties which they possess. For instance isotopes of radioactive elements can be used to label a specific molecule in order to be able to follow the movement of this molecule as it navigates through the human system.
