What else can I help you with?
The cell membrane of red blood cells will allow water oxygen carbon dioxide and glucose to pass through. Because other substances are blocked from entering this membrane is called?
semi-permeable
Why the waste can pass through the membrane?
Waste can pass through a membrane due to its size and composition. Membranes have small pores or channels that allow smaller molecules or ions to pass through, while larger molecules or particles are blocked. Additionally, the chemical properties of the waste may also play a role in its ability to pass through a membrane.
What is partially blocked by ozone in the stratosphere?
Ultraviolet (UV) radiation from the sun is partially blocked by ozone in the stratosphere. Ozone acts as a protective layer that absorbs and scatters harmful UV radiation, reducing the amount reaching the Earth's surface. This helps protect living organisms from the damaging effects of excessive UV exposure, such as skin cancer and eye cataracts.
What kind of light is blocked by sunglasses?
Sunglasses can block both ultraviolet (UV) light and bright glare from visible light, reducing eye strain and protecting the eyes from harmful UV radiation. Polarized sunglasses are effective in reducing glare from reflective surfaces such as water and snow.
What causes nasolacrimal duct occlusion in women and their new born babies?
Babies often have discharge and tearing of the eyes. This is because a membrane in the nose is blocked. Nasolacrimal duct occlusion can happen on one or both sides of the nose. Usually, it opens spontaneously at birth. If the membrane does not open by itself in 6-9 months. The chance that it will self-correct is low and treatment will be required.
Which of the following molecules would be blocked by a cell membrane?
Large molecules such as proteins and nucleic acids are typically blocked by the cell membrane due to their size and complexity. Small, nonpolar molecules like oxygen and carbon dioxide can easily pass through the cell membrane through simple diffusion.
If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face what would happen to you?

semi-permeable
What regulates passage of materials into and out of cells?
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
What single characteristic of the semipermeable membrane used in the laboratory determines the substances that can pass through them?
The molecular size of the substances is the single characteristic that determines which substances can pass through a semipermeable membrane in the laboratory. Smaller molecules can pass through while larger molecules are blocked.

Membranes have small pores or channels that allow smaller molecules or ions to pass through, while larger molecules or particles are blocked.

Why is Webkinz blocked?
If it is blocked at home your parents blocked it, but if it is blocked at school the blocked it because it was a game.
What would happen to a resting membrane potential if the sodium potassium transport pump was blocked?
During depolarization, sodium (Na) rushes into the neuron through Na channels (at the Nodes of Ranvier between the bundles of myelin "insulation"). Less Na in the extracellular fluid would mean there would be less to rush in. So, the neuron would not be depolarized as well. The resting membrane potential would be more positive on the inside.
What is the membrane called if other substances besides water oxygen carbon dioxide and glucose are blocked from entering?
The membrane is selectively permeable if it only allows certain substances like water, oxygen, carbon dioxide, and glucose to pass through while blocking others based on size, charge, or other properties.
Why would blockage of the auditory tube produce an earache?
If the auditory tube were blocked, it would not be possible to equalise the pressure on both sides of the tympanic membrane. If external pressure then declines, the pressure in the middle ear would be greater than that on the outside, forcing the tympanic membrane outward and producing pain.
What would happen if a chemically gated sodium channel in the postsynaptic membrane were completely blocked?
Blocking the chemically gated sodium channel in the postsynaptic membrane would prevent sodium ions from entering the neuron, hindering depolarization and transmission of the signal. This would effectively inhibit the neuron from responding to neurotransmitters released by the presynaptic neuron, leading to a disruption in neuronal communication and a potential loss of function in the neural circuit.
