Provide the seven diatomic elements.
Hydrogen, nitrogen, fluorine, oxygen, iodine, chlorine, bromine. A common mnemonic to recall these is "Have No Fear Of Ice Cold Beer", in which the first letter of each word represents one of the elements.
What type of inheritance pattern would a condition affecting the child of two parents that had no symptoms of the condition be?
In this case, two parents that were asymptomatic for a condition that impacted their offspring would be carriers for an autosomal recessive disorder - one not carried on sex chromosomes but carried by a recessive allele. The child would have received one recessive allele from each parent (carriers), and with no dominant allele to impact the phenotype, they would show symptoms of the condition.
Gatherings of neuronal cell bodies in the central nervous system are referred to as what? What about gatherings of neuronal cell bodies in the peripheral nervous system?
The central nervous system has gatherings of neuronal cell bodies known as nuclei. Nuclei are found all throughout the brain and spinal cord, like the lateral geniculate nucleus in the thalamus which carries signals from the optic nerve. The peripheral nervous system has gatherings of neuronal cell bodies known as ganglia. These ganglia are found in many different places, but perhaps one of the most well known sets is the sympathetic chain ganglia, which run down the vertebral column most of the length of the spinal cord, and carry sympathetic fibers to and from different parts of the body.
