cluponka [151]

Answer:

Electrical gradient.

Explanation:

Ions DO NOT move in Ion channels by simple diffusion because most ion channels can be:

I) selective of ions pass through it.

II) operating on a "open and close" principle. Where it opens or close on its own accord OR does so ONLY when induced by a specific influence like change in voltage of ion channels.

IN ADDITION to the concentration gradient, ELECTRICAL GRADIENTS (change in membrane voltage) affects the movement of ions through ion channels

The bones of the arms, legs, pelvis, and shoulder area
crimeas [40]
The bones of your arms are called humerus, while your forearms are composed of two bones, the radius and ulna. The bones of your fingers are called metacarpals and each one of those small bones are called phalanges.

The bones of your shoulders are composed of the clavicle, the bony part seen just right under the neck. Part of the shoulder area is the scapula, which is located at the back part of the body attached to the upper part of the ribs. They are the triangle-shaped bones you feel when you cross your arms at the back. 

The bones of your thighs are called femur, they are the largest bones in your body. While the bones of your legs are called tibia and fibula. The bones of your toes are called tarsals and each are composed of smaller bones called metatarsals. Your heels also have bones and they are called calcaneus.

The bones of your pelvis are called Coxal bones as a whole but they are composed of the illium (biggest part of your hips); the pubic bone, located along the reproductive organ; the sacrum and coccyx all located at the base of the spine.

Over [174]

In areas where the walls are frequently washed, conduit should be mounted with a 1/4 inch air space between the wall and the conduit.

Conduits are the structures that are hollow and cylindrical like a pipe, channel or tube through which any material can pass. The material can be electrical wires, gases or even water. Therefore, the functions of conduits is to mediate the transport of materials from one place to another.

These conduits can be rigid or flexible depending upon their use and the material to be transported. Care should be taken when these conduits are embedded inside the wall that they are not very close and in contact with the wall otherwise the conduits may get damaged.
