What are the functions of:
salivary
pancreas..

Salivary Glands: The salivary glands produce saliva and excrete amylase. Saliva helps lubricate the mouth and oropharynx. Saliva aids in the easy formation of a bolus, making it easier to swallow. Amylase aids in the break down of carbohydrates. The mouth is where the digestion of carbohydrates begins.

Gallbladder: The function of the gallbladder is to store and concentrate bile. Bile helps emulsify fats and neutralize acids.

Liver: The liver has many functions:
*produce bile
*detoxifies blood
*stores some vitamins and iron
* converts excess glucose to glycogen for storage
*converts ammonia to urea
*destroys old red blood cells, excretes bilirubin
*produces cholesterol
*produces certain proteins for plasma
*regulation of blood levels amino acids
*synthesizes albumin and clotting factors

Pancreas: The pancreas has two functions (exocrine and endocrine). The pancreas produces enzymes to breakdown proteins, lipids, carbohydrates, and nucleic acids  (exocrine). The pancreas secretes the hormones insulin to lowers blood sugar and glucagon to raise blood sugar (endocrine).

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

the answer is "a.) well–developed vascular system."
