Choose one out of paracrine signalling, endocrine signalling,
autocrine signalling and direct signalling and describe briefly the
process by which this occurs.
Pick a representative signal molecule from the pathway you
have chosen and indicate its function, the type of cell in which it
is made and the specific manner in which it acts as a signalling
molecule, including the receptor that it binds to.
Describe the exocrine and endocrine functions of the
pancreas?
Which type of the cells in the
pancreas secrets insulin?
The pancreas is allowed to regenerate
fully after 70% pancreatectomy, what type of cells are the
regenerated insulin-producing cells derived from? What study did
people do to demonstrate this

Part A - Comparing plant cells and animal cells
Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures. In this activity, you will indicate which cell structures are found only in plant cells, only in animal cells, or in both plant and animal cells.
Drag each cell structure to the appropriate bin. If a structure is found in both plant cells and animal cells, drag it to the "both"...
What happens to plant cells when placed in a hypertonic
solution?
What happens to plant cells when placed in a hypotonic
solution?
What is the purpose of Koehler illumination?
What is the satellite communication system, how is the
communication process through it, and what are its types , explain
it ?
"I hope the answer is clear to read it"
1. What step is unique in endocrine system communication
compared to the synapse?
2. What is the major benefit to an animal of a nervous system
instead of merely an endocrine system?
3. How is the pancreas both an endocrine and an exocrine
gland?
Indicate the signals that trigger the release of thyroid hormone
and epinephrine.
4. Release of T4:
5. Release of Adrenalin:
