B. photosynthesis
because it only occurs in plants.
Answer:
The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
Both types of cells need to replicate to create more cells and pass on their genes. Even eukaryotic cells need to replicate to pass on their genes, as not all eukaryotes are animals or plants.
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.
