Nervous tissue consists mainly of neurons and collagen fibers.

Type of anchoring junction.

Produced in the nucleus, this molecule specifies the exact sequence of amino acids of the protein to be made.

When applying Kirchhoff’s rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the potential changes from one end of the resistor to the other. The circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. However, one resistor is marked incorrectly. Which one is it?
