Explanation:
The pressure flow hypothesis, also known as the mass flow hypothesis, is the best-supported theory to explain the movement of sap through the phloem
a fact.
Flowers tend to respond to stimuli
Stimuli are anything that causes arousal or enables an object to respond or react.
There are many different kinds of stimuli for which is different for every organism, for example, water, light and carbon dioxide are three stimuli and materials needed for photosynthesis in plants to manifest.
<span>In humans, we have nutrients or food, oxygen and water for us to survive. These are stimuli, eyes need light as a stimuli for it see and function. Nasal receptors needs smell as stimuli caused by molecular reactions of an object as a stimuli. And others.<span>

Usually occurs in fallopian tube.
RNA polymerase can't bind on the promoter region, so no transcription takes place, consequently, no protein translation.
Answer:The three most important steps of pre-mRNA processing are the addition of stabilizing and signaling factors at the 5′ and 3′ ends of the molecule, and the removal of the introns ((Figure)). In rare cases, the mRNA transcript can be “edited” after it is transcribed.
