Answer: b. nonreducing sugars which include among others raffinose, verbascose and stachyose
Explanation:
Phloem is defined as the vascular tissue which functions for the transport of sugars from source tissues, proteins and mRNAs throughout the plant.
Sugars present in phloem are non-reducing oligosaccherides which includes raffinose, verbascose and stachyose. Verbascose has three α-d-galactose molecules that are attached to sucrose; stachyose has two, and raffinose has one. The oligosaccharides are α-1, 6-galactosyl sucrose extensions (Suc). Those are present in plant phloems like Bignoniaceae, Oleaceae, Celastraceae, Myrtaceae, Verbenaceae and others.
These all functions for the transport of sugar in phloem sap and as storage sugars.
Hence, the correct option is b. nonreducing sugars which include among others raffinose, verbascose and stachyose
Plants that encourage the profileration of nitrogen fixing bacteria are called Legumes
Cutoff signals are signals used by the animals for communication between them. These signals are behaviors. Examples are: the animal freezes, turns the back to other animals, moves away, ....
Cut-off signals are usually given after a conflict. One reason animals use cutoff signals is to:
D. encourage compromise between potential adversaries
If cut-off signals are not respected, conflict will escalate.
