Which of the following is NOT a characteristic of the Kingdom Fungi? MCQ with Answer and Explanation

Explanation:
A balanced diet provides all the essential nutrients (carbohydrates, proteins, fats, vitamins, minerals, and water) in the correct proportions required for optimal health and growth. Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients; therefore, overeating (leading to obesity) is a form of malnutrition. Water is an essential nutrient, crucial for hydration, transport, and chemical reactions, though it provides no calories. Thus, statements 1 and 2 are correct.

Explanation:
Viruses are unique entities containing either DNA or RNA, never both simultaneously, enclosed in a protein capsid. They are obligate intracellular parasites, requiring a host cell's machinery to replicate. Despite being biological entities, they can be crystallized like chemicals, as demonstrated by W.M. Stanley with TMV. Thus, statements 2 and 3 are correct.

Explanation:
Photosystem II (PSII), also known as P680, is the first photosystem in the non-cyclic electron transport pathway (Z-scheme). It is responsible for the photolysis of water, a process where water molecules are split into oxygen, protons (H+), and electrons. This oxygen is released as a byproduct of photosynthesis.
