Yes, like all electromagnetic radiation can be polarized. The A. T. & T. Long Lines Microwave tower system doubled its long distance call capacity by using cross polarized microwaves. This system operated from the late 1940s to the early 1990s (when fibre optics superceded it, but many of the towers and horns remain, see the image above showing a transmitting/receiving pair of horns).
To begin, the correct term is "crossed" polarizer, not cross. The way that a crossed polarizer works is that it contains two polarizers, the first selects a plane of polarized light from an unpolarized light source (containing many oscillations, or planes). The second polarizer than absorbs that plane of polarized light that made it past the first, as it selects a plane of polarized light that is not the one let through the first.
When a pn junction is direct polarized, the height of the depletion layer is reduced and majority charge carriers now have sufficient energy to cross the junction and when it is revers polarized the height of the depletion layer is increased and the number of majority charge with sufficient energy to cross the junction is cut sharply.
No. They can be circularly polarized with the correct phasing harness, or used as a way to switch between horizontal and vertical polarization with one antenna.

Yes, noncatecholamines cross the BBB more readily than catecholamines, because noncatecholamines are less polarized than catecholamines.
Cross polarisation isolation or Cross Polarisation Discrinimation (XPD) is the difference in dB of received signal level (RSL) at the receiver when in turn, the transmitter has the same and different polarisation with the receiver. A antenna with this greater value is prefered. This information is useful in microwace design when in the same area we can use the same frequency with different polarisation . For example: TX1 : vertical polarisation ---> RX1 : Vertical pol. TX2 : horizontal pol. ---> RX2 : horizontal pol. They all operate in the same frequency. The signal from TX1 , TX2 will be separated corresponding to the value of XPD.

They all have cross sections that remain constant when intersected by a plane perpendicular to their lengths.
Myosin heads would remain detached, unable to cock.
yes.
They are called parallel lines, provided they remain the same distance from each other.
Because they remain equal distance apart without intersecting each other.
