question 50

Multiple Choice

Provide an appropriate response.
-A sequence of rational numbers $\left\{ \mathrm { r } _ { \mathrm { n } } \right\}$ is defined $b \mathrm { y } \mathrm {} \mathrm { r } _ { 1 } = \frac { 2 } { 1 }$ , and if $\mathrm { r } _ { \mathrm { n } } = \frac { \mathrm { a } } { \mathrm { b } }$ then $\mathrm { r } _ { \mathrm { n } } + 1 = \frac { \mathrm { a } + \mathrm { b } } { \mathrm { a } - \mathrm { b } }$ . Find $\mathrm { r } _ { 50 }$ .

• A) 3
• B) 49

Electrical Synapses

Specialized junctions between cells that allow for the direct passage of ions and electrical signals, facilitating rapid communication.

Amine Neurotransmitters

Amine neurotransmitters are chemical messengers derived from amino acids that transmit nerve impulses across synapses, including serotonin, dopamine, and norepinephrine.
