Answer:
Dead plant matter
Explanation:
Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.
Answer:
Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integral membrane proteins that allow communication between the cell and the extracellular space.
Explanation:
Answer:
C
Explanation:
I think its C . A transcriptional repressor usually represses the transcription pathway when its active. According to the question, the repressor is not usually active until an effector molecule binds to it making it active and blocking the transcription pathway. So if the region where the effector binds on the repressor is mutated i.e. it turns nonfunctional that means the effector cannot bind to repressor which means repressor cannot become active to block transcription which in turn increases the transcription of gene A because repressor cannot repress it since it is inactive due to its inability to bind to the effector.
ALOT of words please lmk if it makes sense
