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.
Facilitates the roots of plants going down towards gravity and the stems to rise up away from gravity. ... Thus, the difference is that geotropism is driven by gravity and phototropism is driven by light.
The best way of doing it without potentially causing harm to yourself, would be "wafting".
All of the above options are correct because all the given three options are possible
Since chloroplast use energy to make food for plant cells (Photosynthesis) I could compare it to lunch money, and how you have to keep refilling up, and up, just to use it again for food, for yourself.
