Salt water fish actually drink the salt water, excrete the salt, and are left with unsalted water in their body; they do this because the sea water, through the process of osmosis, draws out water from the body. <span>
When they are placed in fresh water, they continue to drink the water, but since the water is now less saline that the fish, water is no longer being drawn out, and in most cases (especially if the transfer was too quick), will start absorbing water, hence they will typically die. </span>
It causes pathogens to stick together.
THe answer to this question would be: ribosome.
Ribosome function is in protein synthesis. To do synthesis a protein, it will need an RNA with a specific structure. The RNA is made from the nucleus, so if nucleus can copy their DNA into RNA, the protein synthesis will not be able to be executed.
Answer:
Sympathetic
Explanation:
Preganglionic motor neurons are a part of the autonomic nervous system - a part of the nervous system that acts mostly involuntarily and regulates bodily functions, such as the heart rate, breathing, digestion, etc.
A preganglionic motor neuron is a type of motor neuron, the cell body of which is located in the brain or spinal cord, while its axon leaves the central nervous system as part of a cranial or spinal nerve before separating and entering the autonomic ganglion.
The preganglionic neurons that originate in the thoracic and lumbar regions of the spinal cord are the sympathetic preganglionic neurons.
The answer is <span>Position emission tomography (PET). The nuclear imaging procedure in medicine is able to detect even molecular activities in a cell. They are
therefore effective in detecting cancers, cardiovascular
diseases, neurological disorders, and etcetera. The radionuclides are modeled
such that they accumulate in the targeted organ. They measure sugar (glucose)
metabolism, blood flow, and oxygen utilization.
