How can you strip the audio from a DVD?

What is a paper?
a strip of wood grinded down to write on
What do different staple sizes like SF 4 SF 3 standard SF 1 indicate?
It indicates how many staples per strip. S.F. 1 and S.F. 4 are 210 staples/strip. S.F. 3 is 105 staples/strip, i.e. a half strip. Larger staplers take the full strip, smaller ones take the half. The S.F. actually stands for "Stapler Food" which personally I find a little stupid, but that's what it stands for... Also, S.F. 1 are standard-quality staples while S.F. 3 and S.F. 4 staples are premium-quality staples.
How do you make a circuit using bimetallic strip?
The bimetallic strip is made of two different metals, bonded together. The two metals have different temperature expansion coefficients, so when the bonded assembly is heated or cooled, it curves one way or the other, allowing a switch to be opened or closed.
How could you measure the perimeter of a round object using a ruler?
Wrap the strip of paper around the plate or can and mark it where it completes a full circle around the object. Then lay the strip on a flat surface and measure the marked length using the ruler. That length is the perimeter (circumference) of the round object.
The casparian strip prevents water and minerals from entering the stele through?
Apoplast
The waterproof strip that surrounds cells of the endormis is the?
I think the answer is b which is vascular cylinder
What is the chemical nature of the casparian strip how does it affect the movement ot water in the root?
The casparian strip contain suberin.
What might happen to a plant whose endodermal cells lacked a Casparian strip?
Casparian strip allows movement of fluid from endodermis to the cortex. In endodermal cells lacking casparian strip there will be no movement of fluid across these cells.
What is the role of casparian stripe?
To understand the purpose of the Casparian strip we must first understand what it is. The Casparian strip is found in the root of the plant. It is a barrier made of suberin, a waxy material that is impervious to water and dissolved minerals that is located in the transverse and radial walls of the endodermal cells - the final barrier between the outside and its various harmful materials and the vascular tissue. Another thing we need to understand is the transport routes of water and its dissolved nutrients and minerals from root to vascular tissue. There are three routes - the symplastic route - a route that goes through the cytosol of cells (which is continuous thanks to cytoplasmic channels called plasmodesmata) exclusively. The cytosol of the cells is collectively referred to as the symplast. the apoplastic route - a route that goes through the cell walls of cells (which are also continous) exclusively. The celle walls, extracellular spaces and dead interiors of tracheids and vessels are known collectively as the apoplast. the transmembrane route - like the name suggests, a route that goes through both the symplast and the apoplast. But recall that the Casparian strip is IMPERVIOUS to water! It forces water on apoplastic and transmembrane routes to cross the membrane of the endodermal cell to enter the vascular tissue via symplast. Why is this important? Recall again that the endodermal cells are the last gateway to the vascular tissue. When water is forced to detour into the cell because of the Casparian strip, it must cross the selectively permeable plasma membrane. While the Casparian strip doesn't serve as a gateway, it has a vital purpose. It is kind of like a security guard in front of a metal detector at the airport - it ensures that everything going onto the plane (into the vascular tissue) is thoroughly checked.
The endodermis a is the outer covering of the root b is part of the vascular tissue c contains the Casparian strip which regulates the movement of substances d is none of the above?
the answer is (c) contains the Casparian strip, which regulates the movement of substances
What is the physical barrier in the root that regulates the flow of water to xylem via cell walls?
the endodermis
There is a one-way movement of water and minerals from the cortex into the vascular cylinder of a root because?
of the Casparian strip, which is a waterproof zone.
Where is the Casparian strip located?
It's a control system which blocks the movement of the solutes and prevents diseases and parasites to enter the plant.
What is the function of a casparium strip?
The casparian strip is a waterproof barrier in the endodermal cells of plant roots that regulates the passage of water and nutrients into the vascular system. It ensures that all materials entering the plant must pass through selectively permeable cell membranes, helping to maintain nutrient uptake and prevent the entry of toxic substances.
What is A waxy barrier in the plant root?
A waxy barrier in plant roots typically refers to the presence of a specialized layer of cells or substances that have a waxy or hydrophobic (water-repellent) nature. This waxy layer is often referred to as the "Casparian strip" and is found in the endodermis, a tissue layer in the root that surrounds the vascular cylinder. The main function of the waxy barrier, or Casparian strip, is to regulate the movement of water and nutrients into the plant through the roots. It acts as a selective barrier that prevents the passive movement of water and dissolved substances between cells, forcing them to pass through the cell membranes and into the cytoplasm before entering the vascular system. This barrier is crucial for maintaining proper nutrient uptake and preventing harmful substances from entering the plant. It ensures that the plant has control over what enters its vascular system, allowing it to selectively absorb beneficial nutrients while excluding potentially harmful elements. In essence, the waxy barrier in plant roots helps maintain the plant's health by regulating the passage of water and nutrients, ensuring a controlled and efficient uptake process.
What is the Casparian strip associated with?
The Casparian strip is a band of cell wall material deposited on the radial and transverse walls of the endodermis, which is chemically different from the rest of the cell wall. The Casparian strip consists of lignin and suberin which is a waxy material specially modified from primary carbohydrates and which is deposited in the primary cell wall and middle lamella. Water moves across the root via three different pathways. One path is the apoplastic path where the water molecule stays between cells in the cell wall region, never crossing membranes or entering a cell. The other two routes, called cellular pathways, require the water molecule to actually move across a membrane. The first cellular pathway is the transmembrane path where water moves from cell to cell across membranes. It will leave one cell by traversing its membrane and will re-enter another cell by crossing its membrane. The second path is the symplastic path which takes the water molecule from cell to cell using the intercellular connection called the plasmodesmata which are membrane connections between adjacent cells. Regardless of the pathway, once the water molecule has traversed the cortex, it must now cross the endodermis. As said earlier, the endodermis contains the Casparian strip that stops the water movement between cells. At this point, water is forced to move through the membranes of endodermal cells, creating a sieving effect. In this way, the amount of water passing into the xylem is regulated as well as other nutrients and solutes. Leckraz Kaul
