Answer:

False

Explanation:

The glycocalyx is the layer surrounding the plasma membrane of the eukaryotic and prokaryotic cells.

The glycocalyx is composed of the carbohydrates and the protein molecules like the proteoglycans, glycosaminoglycans and the other glycoproteins.

The glycocalyx has been identified in the bacterial cells as a protective layer from the host bu in eukaryotes the glycocalyx helps in the cell to cell interaction and communication.

Since the glycocalyx is not composed primarily of the proteins but of the carbohydrates and the proteins therefore false is the correct answer.

Answer: False. It is not glycocalyx.

Explanation:

Glycocalyx is a carbohydrate enriched membrane bound layer that surrounds the cell plasma of eukaryotic cells and prokaryotic cells, especially bacteria. It act as a barrier between the cells and its environments. In bacterial cell, it act as protective coat from host factors.

Glycocalyx help in cell to cell interaction or communication in eukaryotic cell. It is involved in diseases development and progression.

Radioactive materials that are high energy and will cause cellular and tissue damage are called:______.
s344n2d4d5 [400]

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.
