ANSWER ➤A: Lichen
Explanation: Certain species of lichen are now recognized as indicators of environmental pollution because they have a chemical defense strategy in their habitat. Research has shown that half of lichen species will have some type of chemical that is antibiotic. Because of this, they are seen as indicates of environmental pollution.
I hope this answer is helpful to you, but please let me know if you have any other questions regarding it.

seeks to help communities mitigate and adapt to climate change, as well as improve food security.
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.
