The nucleus would be damaged.
If the nuclear membrane became permeable to most substances, it would disrupt the delicate environment required for DNA and RNA processes, potentially leading to a loss of cellular control over gene expression and regulation. Proteins and other molecules that are normally compartmentalized would diffuse in and out freely, compromising the integrity of genetic material and cellular functions. This could result in cell malfunction, increased susceptibility to damage, and possibly cell death or uncontrolled proliferation, contributing to diseases like cancer. Overall, it would severely impact cellular homeostasis and function.
Heat causes the cell membrane of beetroot cells to become more permeable, leading to the release of red pigment (betacyanin) into the surrounding environment. This results in the characteristic color change of beetroot from red to a lighter pink or yellow when heated.
The phase where the nucleus and the nuclear membrane disappear is called prometaphase. This is the phase following prophase in mitosis or meiosis when the nuclear envelope breaks down and the chromosomes become more condensed and visible.
The nucleus of the chemical element with atomic number 2 is known as an alpha particle. It is emitted by some radioactive substances during the process of alpha decay, where a parent nucleus releases an alpha particle to become a more stable daughter nucleus. Alpha particles consist of two protons and two neutrons bound together.

The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and depolarization of the membrane. This depolarization triggers an action potential that leads to muscle contraction.

If the membrane is not permeable to either sodium and chloride ions or water then the concentrations of the liquids would remain the same. However, if the membrane was permeable to water or the ions then the plain water would become more salty while the salty water would become more dilute (due diffusion/osmosis, depending on the membrane's permeability).

it would die as harmful substances entered the cells. (APEX)
Both the heart rate will decrease and the membrane will hyperpolarize

Nephrons are the basic functional unit of the kidneys. They take in blood through an afferent arteriole and filter it inside the Bowman's capsule in a series of capillaries called glomeruli. It is the walls of the glomeruli that contain the membrane, more accurately called semi-permeable membrane, that removed the serum from the blood to produce the filtrate that will eventually become urine.
A Visking tube, also known as dialysis tubing, is a semi-permeable membrane often used in experiments to demonstrate osmosis and diffusion. For example, in a classroom setting, a Visking tube can be filled with a sugar solution and submerged in plain water. Over time, water molecules will move into the tube through the membrane, causing the sugar solution to become more dilute and illustrating the principles of osmosis. This setup effectively shows how substances can move across selectively permeable membranes.
