They will actually explode or burst
So What happens is the pure water outside has a high water potential while the cytoplasm inside the animal cell is a low water potential, water will diffuse down a water potential gradient through the semi-permeable membrane of the animal cell and cause the cell to swell (inflate like a fully-blown balloon), the result is that the delicate, elastic cell membrane<span> can't tolerate the internal pressure coming from the cytoplasm so it tears causing the cell to burst.</span><span>

Answer:
The given situation is an example of the <u>Positive feedback loop</u><u>.</u>
Explanation:
Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.
<u>Therefore, the given situation is an example of the </u><u>Positive feedback loop</u><u>. </u>
The speed of sound wave is slower than electromagnetic wave.
Answer:
The correct answers are option A. "tethering proteins to the cell cortex", B. "using barriers such as tight junctions", C. "tethering proteins to the extracellular matrix", D. "forming a covalent linkage with membrane lipids", E. "tethering proteins to the surface of another cell"
Explanation:
According to the fluid-mosaic model, the components of cell membranes are in constant movement forming a barrier to avoid unwanted exterior component internalization and to avoid the loss of precious internal components. This constant movement could cause that proteins move across the plasma membrane. But, this is avoided by several mechanisms including:
A. Tethering proteins to the cell cortex. The cell cortex is a rigid structure made of actin and actomyosin. Proteins found in the plasma membrane are tethered to this structure to restrict their movement.
B. Using barriers such as tight junctions. Tight junctions are barriers found in epithelia made of claudin and occludin proteins. These barriers are impenetrable, which avoid the movement of proteins in the cell membrane.
C. Tethering proteins to the extracellular matrix. The extracellular matrix is made of several proteins and macromolecules that provide a structural and biochemical support to cells that are nearby. Proteins could be tethered to this rigid structure as well.
D. Forming a covalent linkage with membrane lipids. The proteins in the cell membrane that form a covalent linkage with membrane lipids are known as lipid-anchored proteins, or lipid-linked proteins.
E. Tethering proteins to the surface of another cell. When cell-cell communication take place it is possible that proteins in the cell membrane got tethered to the surface of the other cell.
