The endoplasmic reticulum (ER) is the extensive internal membrane system responsible for synthesizing proteins and steroids in eukaryotic cells. It consists of two types: rough ER, which has ribosomes on its surface for protein synthesis, and smooth ER, involved in lipid and steroid synthesis.
The autonomic nervous system is concerned with the internal organs, controlling involuntary functions like heart rate, digestion, and respiratory rate. The somatic nervous system, on the other hand, regulates voluntary movements and sensory information from the external environment.
The three internal variables that are concerned with homeostasis are body temperature, blood glucose level, and blood pH. These variables must be regulated within a narrow range in order for the body to function properly and maintain equilibrium.
Internal energy is an extensive state function. That means it depends on how much of a substance you have but if you fix the composition, pressure, temperature, volume, and (in the case of a system at a phase equlibrium point, like water at the freezing point) the phase of a system, the specific internal energy will be constant. If you take a closed system and change the volume of it, you will be doing work (or allowing the system to do work) and the internal energy can change - so - yes - internal energy of a system depends upon volume. Also, if you fix the composition, temperature, pressure, and phase of a homogeneous mass but change the volume, you will increase the amount of mass you included in the system, thus changing the total internal energy (because it is, after all, an extensive function).
Stop trying to cheat. Biomechanics is the science concerned with the action of forces internal and external on the living body. Kinesiology is the science or study of movement, and the active and passive structures involved.
No, DNA synthesis does not occur in the cell membrane. DNA synthesis occurs in the cell nucleus where the genetic material is contained. The cell membrane primarily functions as a physical barrier that separates the cell's internal environment from the external environment.
Enthalpy is an extensive quantity because an extensive quantity depends on the size of the molecule or the number of moles (how much of the molecule you have). Therefore think of a handful of gunpower vs. a storage room full of gunpower. Which reaction will have more enthalpy change? Yes, the room full of gunpower because there is more gunpowder in the reaction. This is an example of why enthalpy is an extensive quantity. Hope you understand now.
Internal bleeding.
The accounting process is concerned with both: internal and external transactions representing economic events.
Endoplasmic reticulum (er)
Internal auditors identify control problems and develop solutions for improving and strengthening internal controls. Internal auditors are concerned with the entire range of an organization's internal controls
