Answer: Nucleus membrane isn't part of the ER or Golgi Apparatus, BUT all of them are part of the endomembrane system.
Endoplasmic reticulum and Golgi apparatus are two membrane-bound organelles found in eukaryotes. Both these organelles are closely associated and functionally related. Both endoplasmic reticulum (ER) and Golgi apparatus are two components of the endomembrane system of a cell. Lysosomes and vesicals are the other components of the endomembrane system.
Answer:
smooth muscle and cardiac muscle only.
Explanation:
because all of these muscles are involuntary meaning all of these muscles are not moveable by choice, you can not decide when to move these muscles. Foe example we can not control the heart muscles, the heart needs to pump involuntary, but the other muscles from the list we have control over. For example we can make a choice when it comes to moving some skeletal muscles, but not a choice when moving smooth muscle and cardiac muscle .
It will transported across plasma membrane by simple diffusion. simple diffusion refers to a process by which molecules will pass across plasma membrane without the aid of channels located on the surface of the membrane. since the molecule identified was polar once it enter in hydrophobic region of the membrane it will not stick since this region is non-polar and therefore it will move easily across that region.
Nutrients cross the membrane wall with the help of protein channels.
