Answer: Option (d) is the correct answer.
Explanation:
Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.
But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.
This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.
Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.
Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.
Carl Woese distinguished between the members of the archaea and the bacteria using studies of their ribosomal RNA.
What is ribosomal RNA?
Ribosomal RNA (rRNA), a particle in cells that are sent out to the cytoplasm and is a part of the protein-creating organelle known as a ribosome, supports the change of courier RNA (mRNA) into protein. Moreover, ribosomal ribonucleic corrosive is a type of non-coding RNA that fills in as the primary structure block of ribosomes, which are essential for all cells. Protein combination is done by rRNA, a ribozyme, in ribosomes. In spite of never being converted into proteins, it makes up around 80% of cell RNA.

Answer:
The answer is mitochondira of heterotoph cells
Explanation:
Positive selection tests to see if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
<h3>What is a T-lymphocyte?</h3>
A T-lymphocyte is a special type of immune cell that is generated inside the bone marrow.
The T-cell receptor (abbreviated as TCR) is a protein located on these immune T lymphocytes.
In conclusion, Positive selection identifies if the TCR of a T-lymphocyte can recognize and bind to an MHC molecule.
