In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>
Because we do or we would die
Answer:
<h3>True</h3>
Explanation:
Topography is a detailed map of the surface features of land.
An error in transcription/translation affects only one cell.
An error in DNA replication would affect many generations of cells.
