Answer: Option A) 99% of that in the entire atom

Explanation:

An atom consists of three subatomic particles named protons, neutrons and electrons. The protons and neutrons are found in the nucleus of the atom, while the mass of electrons is 1/1840 (negligible).

Thus, the mass of protons and neutrons in the nucleus makes 99% of the entire atom

zavuch27 [327]

Answer:

The moment where the nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called Telophase.

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.
