Answer:
Excision category (20150-20251) codes are for the biopsies of muscle and bone. The codes are divided based on the type of biopsy (muscle, bone), the depth of the biopsy (superficial, deep), and, in some codes, the method of obtaining the biopsy (e.g., percutaneous needle).

Answer:
(b) Voltage gated
Explanation:
The cell membrane acts as a barrier that separates two aqueous media of different composition, the extracellular and the intracellular, regulating its composition. Most of the liposoluble drugs and solutes, when not ionized, directly cross the cell membrane through a passive diffusion process, which facilitates the passage of the medium where it is more concentrated to the one that is more diluted. The difference in concentration between the two media is called the concentration gradient, and diffusion will continue until this gradient is eliminated. According to Fick's law, the speed of this process will be much faster the higher the concentration gradient and the liposolubility of the molecule and the smaller its size.
More hydrophilic molecules, such as ions, are immiscible in membrane lipids and pass through specific specific transport mechanisms. In some cases, ions pass through hydrophilic pores called ion channels, and in others a favor of their concentration gradient is transported by binding to the transporter or transporter proteins. Both transport systems are passive and therefore do not consume energy. The great advantage is that the ion channels allow the flow of ions through a much higher speed than that of any other biological system. The flow of ions through each channel can be measured as an electric current, which is capable of producing rapid changes in membrane potential.
Well the endoplasmic reticulum has both smooth and rough bodies. Smooth is the synthesis of fats and detoxifies harmful bodies. Mostly in the liver. And the rough mainly synthesize proteins which are basic components of life. Proteins are sent all over the body and are used for many functions. The golgi is used to package those proteins and send those proteins through the body. Mitochondria creates energy and is the power house of the cell. And the plasma membrane is like the gate keeper. Decides what can enter it exit the cell and prevents harmful things from coming in. Allows proteins to leave.
Hello. this is very simple. i know it and im in middle school. dont highschoolers know that you can just ask google and get a verified answer in just a few seconds?
sighs, well i guess older kids dont get technology as much as we do.
no offense, but seriously if you pay more attention in class you might not be asking this silly question right now.
Molecule which enzyme<span> acts on = the substrate. 5. Substrate molecule is held within the active site by bonds that temporarily form between certain amino acids of the active site and groups on the substrate molecule. ...
