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.
Answer: Meditation
Explanation: Meditation is an exercise where a person uses a method such as intentionally bringing one's awareness to encounters happening in the very period with no judgment or concentrating the psyche on a specific matter, reasoning or training. This is done to teach the mind the skill of the mental action of deeming or taking notice of somebody or something, and perception of reality or circumstance thereby attaining a mentally clear, emotionally quiet and firmly established condition.

Answer:
Decomposers are also called saprotrophs
Explanation:
Decomposers are heterotrophic because they have to take their nutrients from other sources instead of making it themselves, unlike the autotrophs. ... decomposers like the fungi and bacteria that decompose dead organic matter and release their nutrients for use by other organisms.
