The Nucleus would be damaged. Apex
What else can I help you with?
What would happen if the membranes of a nucleus became permeable to most substances?
The nucleus would be damaged.
What would happen if the membrane of a nucleus become permeable to most substances?
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.
What is the effect of heat on beetroot?
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.
What phase does the nucleus and nucleus disappear?
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.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
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.
What would happen if the membrane of nucleus became permeable to most substance?
The nucleus would be damaged.
What would happen if the membranes of a nucleus became permeable to most substances?
The nucleus would be damaged.
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and blank of the membrane?
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.
Binding of the neurotransmitters with muscle membrane receptors causes the membrane to become permeable to sodium resulting in the influx of sodium ions an what of the membrane?
depolarization
When hinding of the neurotransmitters with muscle membrane receptors causes the membrane to become permeable to sodium resulting in the influx of sodium ions and what membrane?
action potential of the sarcolemma(the membrane)
Two liquids are sepertated by a membrane that is not permeable one liquid has a high concentration of salt the other liquid is plain water you can expect?
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).

What would happen to an organism if its cell membranes became permeable to most substance?
it would die as harmful substances entered the cells. (APEX)
If the pacemaker cells in the SA node become more permeable to potassium ions the?
Both the heart rate will decrease and the membrane will hyperpolarize

What is the membrane of a nephron?
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.
Give example of visking tube?
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.
