Sink to the bottom because it is more dense than the water.
<span>Explanation: Oxygen is the more electro-negative of the atoms in the water molecule, so it tends to pull the 'shared' electron more to itself. Thus, the oxygen atom has a greater time-share of all electrons, and therefore the hydrogen atoms are more positive for a partial lack of electrons</span>

Answer:
The correct answer is duodenum
Explanation:
Bile is a digestive enzyme that is secreted by the liver which is temporarily stored in the gall bladder and pancreatic enzyme is released by the pancreas. The bile is secreted to the small intestine through the common bile duct and the pancreatic duct joins the common bile duct just before ampulla of Vater which opens in the first intestinal portion which is duodenum.
So bile and pancreatic enzymes enters the duodenum region of the small intestine and after getting in the small intestine it digests the complex macromolecules into simpler and smaller form which can be absorbed through the intestinal epithelium.
Induced depression of single neurons in brain areas with opiate receptors
- Enkephalin, applied microiontophoretically, depressed spontaneous and glutamate-induced firing of one neuron in frontal cortex, caudate nucleus, and periaqueductal gray matter, where enkephalin and high concentrations of opiate receptors are met.
- More than one depressions were blocked by the specific narcotic antagonist naloxone. The results are durable with a neurotransmitter or neuromodulator role for this new brain pentapeptide.
- Opium derivatives have been in medical use for the last 2000 years, and may be longer than any other class of drugs
- . The brain regions which was involved in these actions have been identified in some instances by local microinjection of pmole quantities of opioids.

Answer:
By doing more research.
Explanation:
The cell theory change with the passage of time by doing more research about the cell. The final modification of the cell theory done by Rudolf Virchow in 1855 on the basis of his new research and findings about the cells. With the passage of time, modification occurs in microscope which enable the scientists to find different parts, organelles and features of cell on the basis of which scientists modify cell theory with the passage of time.
