Atomic lattices (like graphite) and more specially metal atomic latice behave
very differently to electrons (current) compared with positive metal ions in their latice together with negative anions (called ionic lattice).
Conductive materials are generally not suitable for hanging armored cables, as they can pose safety hazards such as electrical shorts or shocks if the cable insulation is compromised. Instead, non-conductive materials like plastic or nylon are preferred for support structures to ensure safety and integrity. Additionally, using appropriate mounting hardware designed for armored cables helps maintain their protective features and prevents damage.
Light receptor cells, such as photoreceptors in animals (like rods and cones in the retina), have distinct structures that differ from plant cells. While both types of cells share some basic components, such as a cell membrane and cytoplasm, photoreceptor cells are specialized for detecting light and do not have cell walls or chloroplasts, which are characteristic of plant cells. Instead, they contain specialized proteins and organelles adapted for converting light into electrical signals. Thus, although they share some cellular characteristics, their structures and functions are quite different.
Rocks are not best described as structures; they are more accurately defined as natural solid aggregates composed of one or more minerals or mineraloids. While rocks can exhibit structural features, such as layering or foliation, these characteristics result from geological processes rather than indicating that rocks themselves are structures. Instead, structures typically refer to the arrangement and organization of materials within a rock or geological formations.
There are two main types of conductors: 1) electrical conductors, which allow the flow of electrical current, and 2) heat conductors, which allow the transfer of thermal energy. Some materials can serve as both electrical and heat conductors, while others may only be conductive in one form.
Plastic is generally considered a poor conductor of heat and electricity, meaning it does not effectively transfer thermal energy or electrical current. Instead, it acts as an insulator, making it suitable for applications where heat or electrical insulation is needed. Some specialized plastics can have enhanced conductive properties if modified or combined with conductive materials, but in its standard form, plastic is not a good conductor.
Steel is not ideal for electromagnets because it has low electrical conductivity and high hysteresis loss, which reduces the efficiency of the electromagnet. Instead, materials that have higher electrical conductivity, such as iron or soft magnetic materials like iron-nickel, are preferred for electromagnets. These materials provide better magnetic properties, allowing the electromagnet to generate a stronger magnetic field.
Aliens may not have even built them. Although, if they did why would they, let alone use metal?
Materials that can be used instead of glass for picture frames include acrylic, plexiglass, and polycarbonate.

Chameleons do not have external ears like many other animals, but they do possess internal ear structures. These structures allow them to detect sounds and vibrations, although their hearing is not as acute as that of some other reptiles. Instead, chameleons rely more on their vision and other senses for communication and navigation.

Basically, the same way you be an electrical technician in the US, except you watch Hockey instead of Football.
Yes.
Some alternatives to electrical tape include heat shrink tubing, liquid electrical tape, self-fusing silicone tape, and vinyl electrical tape.
Conifers have structures known as cones instead of flowers. Cones are the reproductive structures of conifers that contain seeds. They are typically found on both male and female trees.
No, it is not safe to use duct tape for electrical purposes. Electrical tape is specifically designed to insulate and protect electrical connections, while duct tape is not. Using duct tape for electrical purposes can pose a safety hazard.
