Nervous tissue consists mainly of neurons and collagen fibers.

Type of anchoring junction.

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?

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

A beam consisting of five types of ions labeled A, B, C, D, and E enters a region that contains a uniform magnetic field as shown in the figure below. The field is perpendicular to the plane of the paper, but its precise direction is not given. All ions in the beam travel with the same speed. The table below gives the masses and charges of the ions. Determine the magnitude of the magnetic field if ion A travels in a semicircular path of radius 0.5 m at a speed of 5 × 106 m/s. Note: 1 mass unit = 1.67 × 10–27 kg and e = 1.6 × 10–19 C

The drawing shows four situations in which a positively charged particle is moving with a velocity v→{“version”:”1.1″,”math”:”v→”}  through a magnetic field B→{“version”:”1.1″,”math”:”B→”}. In each case, the magnetic field is directed out of the page toward you, and the velocity is directed to the right. In only one of these drawings is the magnetic force F→{“version”:”1.1″,”math”:”F→”} physically reasonable. Which drawing is it?

A 2 mm diameter wire of length 20 m carries a 200-mA current when a voltage of 0.05 V is applied across its ends. What is the resistivity of the wire?

This organelle contains oxidases and catalases.
