Hey there are you going home
Antigens; they are molecules that are foreign to the body, thus stimulating a response by the b- and t-cells that aim to defend the body against harmful and mostly foreign bacteria.
Answer:
UGA
Explanation:
There are 64 different codons in the genetic code and the below tables; most specify an amino acid.[7] Three sequences called stop codons, UAG, UGA, and UAA,[note 1] do not code for an amino acid but instead signal the release of the nascent polypeptide from the ribosome.[8] In the standard code, the sequence AUG—read as methionine—can serve as a start codon and, along with sequences such as an initiation factor, initiates translation.[3][9][10] In rare instances, start codons in the standard code may also include GUG or UUG; these codons normally represent valine and leucine, respectively, but as start codons they are translated as methionine or formylmethionine.[3][10]
Complete question:
Postganglionic neurons of the autonomic nervous system __________.
a) stimulate skeletal muscle
b) stimulate preganglionic neurons
c) have cell bodies located within autonomic ganglia
d) are afferent
Answer:
c) have cell bodies located within autonomic ganglia
Explanation:
A group of cell bodies of neurons in the peripheral nervous system is called a ganglion. Most of the motor pathways of the autonomic division have two motor neurons in series. The first neurons in the series are called preganglionic neurons. Their cell bodies are present in CNS. The second neurons of the autonomic motor pathway are called postganglionic neurons. The cell bodies of these neurons are present in the same autonomic ganglion.
