A half-life of a radioactive substance is the amount of time needed for one half of _____ to decay into a stable isotope.A) the neutrons in the nuclei

B) its beta particles

C) the nuclei in a sample

Answers

Answer 1
Answer: A half-life of a radioactive substance is the amount of time needed for one hald of the nuclie in a sample to decay into a stable isotope.Many protons and neutrons disturb the balance of binding energy from a strong nuclear forces resulting for the nucleus to be unstable. To be in a balance state, the unstable nucleus will give off a proton or neutron through radioactive decay.
Answer 2
Answer:

nuclie in a sample is the answer

If a cell with six chromosomes undergoes mitosis, it will produce____________ (number) daughter cells that contain ______________ (number) chromosomes.

Answers

Mitosis is a type of cell division where one parent cell divides to produce two genetically identical daughter cells. In diploid organisms, mitosis produces diploid daughter cells.

  • If a cell with six chromosomes undergoes mitosis, it will produce TWO daughter cells that contain SIX chromosomes.

  • A diploid (2n) organism has two copies of each chromosome in its somatic cells.

  • Mitosis can be divided into the following stages: prophase, metaphase, anaphase and telophase.

In conclusion, if a cell with six chromosomes undergoes mitosis, it will produce TWO daughter cells that contain SIX chromosomes.
