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.

C : You would see a solid piece of wire underneath the coating.
The awnser is b there is a mutation in the gene
Answer:
Independent - Water/Type of water (salt and pure)
Dependent - Height of plant
Controlled - Amount of water
Explanation:
Independent is what the experimenter manipulates (in this case being the type of water.)
Dependent is what the experimenter measures and is a result of the independent (in this case being the height of plant)
Controlled is what you are trying to keep the same (in this case the amount of water you give each plant.)
The correct answer is - lung cancer.
The asbestos is a material that has been used very often in the past, mostly for making water pipes and roofs. Few decades ago it was proven that the asbestos actually breaks down into microscopic little pieces that are extremely dangerous. This little pieces, if inhaled, can gradually result in the development of a lung cancer. Because of what the research had shown, lot of people and institutions were in panic, so urgent and quick measures were taken in order to change the water pipes and the roofs.
