Radioactive materials that are high energy and will cause cellular and tissue damage are usually known as ; Alpha radiation.
<h3>
What is Radioactive material and Alpha Radiation ?</h3>
- Chemicals in the class of radionuclides (also known as radioactive materials) have unstable atomic nuclei. They stabilize themselves by altering the nucleus (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons or the reverse).
- For example, the Earth's crust naturally contains the radioactive elements uranium and thorium. These two elements slowly alter their forms over billions of years, leading to the production of decay byproducts like radon and radium. Energy is released during this process. Alpha radiation is one type of this energy.
- Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.

Answer:
some molecules pass
Explanation:
The ability of a membrane to pass or not to pass a substance is its permeability (permeability).
Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.
The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.
Areoles are the tissue that make up most of the stem of cacti. These are specialized structure that give birth to flowers and are often tubular and multipetaled. This structure enables the plant to survive in the harsh conditions of the desert and help them absorb water from the soil efficiently.
The answer is obviously not C as urine comes out of your urethra, so the answer is a and b
