Answer:
True
Explanation:
Periaqueductal gray matter is found in the middle portion of brain. When this grey matter is stimulated it activates neurons that releases enkephalin. Enkephalin further direct the stimulation to the raphe nuclei with in the brain stem that releases serotonin. In this process, the ascending and descending axons are released from
a) subcortical nuclei
b) spinal trigeminal nuclei
c) the spinal cord
Hence, the given statement is true
Answer:
Most attenuated vaccines are viral, some are bacterial in nature. Examples include the viral diseases yellow fever, measles, mumps, and rubella, and the bacterial disease typhoid

food chain:The simplest representation of energy in a community. At the base is energy stored in plants, which are eaten by small organisms, which in turn are eaten by progressively larger organisms; the food chain is an oversimplification in that most animals do not eat only one type of organism.

food web:the interconnected feeding relationships in an ecosystem. These relationships can be complex; some organisms may feed on more than one trophic level, or changes may occur depending on a species' life history stages or the availability of food.
You subtract the number of protons and the mass to get the number of neutrons.
