Lipid-soluble materials enter and exit the cell via?
Phospholipids permit lipid-soluble materials to easily enter or leave the cell by diffusion through the cell membrane. Phospholipids form a bilayer or double layer which makes up most of the membrane.
What tool or instrument might a student use to observe the tiny holes in a leaf called stomata through which gases enter and leave the plant?
A microscope can be used for this.
What controls substances that enter and leave the cell?
IT depends on what cell. In the plant cell it is the cell wall and the cell membrane. But in the animal cell it is only the cell membrane.
What is the passage of an EM wave through a medium?
when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.
What are the conductors and insulators in a simple circuit?
All materials are conductors and insulators to some extent. Materials called "conductors" have very high conductivity, and materials called "insulators" have very low conductivity. Wires are the conductors in a circuit. Wires are usually wrapped with insulators so that accidental contact between wires does not cause a "short" and prevent the circuit from working as designed. Also, air is a good insulator that is usually implicitly present between the components of the circuit. These insulators are not drawn on a circuit diagram. They are represented by the absence of a connection drawn on the diagram. In a sense, they are not part of the "circuit", because they are not part the path taken by the vast majority of electrons. Resistors are a kind of electrical component that is between a conductor and an insulator. They can conduct electricity to some degree, but less than a wire. Capacitors contain an insulator called a "dielectric". This material does not allow electrons to pass. However, current can pass through a capacitor. Excess electrons can accumulate on one side of the capacitor, while electrons are drained from the other side. No electrons actually pass through the capacitor, but they seem to because the same number enter on one side as leave on the other.
Do the Materials enter and leave the nucleus through the cromatin?
Materials usually enter through the cell wall.
Materials enter and leave the nucleus through opening in its?
materials enter and leave the nucleus through openings in its cell wall and membrane
How do materials enter and leave the nucleus?
Materials enter and leave the nucleus through the selective membrane. The membrane always controls what leaves and enters the nucleus.
Food and other materials enter and leave the cell through openings in?
Cell Membrane
What Materials enter and leave the cell through openings in its?
Cell Membrane
Why is it important for the cell membrane to allow materials to enter and leave the cell?
Cell membranes regulate several materials that enter the cell. Cell membranes regulate proteins, as well as other materials that enter or leave the cell.
Process by which materials enter and leave a cell through the cell membrane?
i am the most awesome person in the world
What membrane serves as the boundary between the cell and its environment allows materials such as oxygen and nutrients to enter and waste products to leave?
The Plasma membrane.
Why must materials enter and leave the cell?
numbers
What is the process by which materials enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated diffusion
The what controls the materials that enter and leave the cell?
cell membrane
What structure allows materials to enter and leave the cell?
