whats the function of the pancreatic juice?

the pancreatic juice contains
pancreatic amylase-digests starch into maltose
pancreatic lipase-digests fats into 3fatty acids and 1glycerol
trypsin-digests peptides and protiens into amino acids

Thanks ! 

In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose, a sugar, to all parts of the plant where needed. In trees, the phloem is the innermost layer of the bark. The phloem is mainly concerned with the transport of soluble organic material made during photosynthesis. This is called translocation.

hope tht helps .

By the way... what are the decay products when bacteria act on dead organisms?
do they release Nitrogen gas, or ammonium compounds?

Q:How blood provides suitable conditions for the reproduction of viruses.

The tracheids, fibres, and vessels present in the xylem, become lignified during development, losing their living contents. This makes the tissue impermeable (to water) so none is lost as water is transported via the xylem. The tracheids' bordered pits allow for the rapid movement of water from cell to cell.

As is with tracheids, the lignification of vessels can occur as rings, spirals, scalariform or reticulate. In the first formed xylem, rings and spirals occur more frequently. This allows for a limited amount of stretching which may occur in young structures.

Both tracheids and vessels provide a pathway for the transportation of water, whilst also contributing to support.

Hope tht helps!

thanks mate... but is that it?
can u just tell me the other products...?
thanks alot..
