PSII also involve in oxidation of water molecules, water is a very stable molecule that’s why  Oxidation of water to form molecular oxygen is very difficult, Many studies have provided a substantial amount of information about the process known;

which of the following are false ?

#Unit 6. System Physiology – Plant
  1. The photosynthetic oxygen-evolving complex is the only known biochemical system that carries out water oxidation process
  2. The protons produced by water oxidation are released into the lumen of the thylakoid, not directly into the stromal compartment because of the vectorial nature of the membrane
  3. The fact that the oxygen-evolving complex is localized near the exterior surface of the thylakoid membrane
  4. The protons produced by water oxidation are eventually transferred from the lumen to the stroma by translocation through the ATP synthase, In this way, the protons released during water oxidation contribute to the electrochemical potential driving ATP formation.

 In a bird species A, the male alone builds the nest, incubates the eggs and feeds the nestling. In bird species B, it is the female that does all that. In bird species C, both sexes contribute equally to the above activities. In species A and B, the uninvolved partner may fly away and mate again. Which sex among A, B and C is most likely to develop colorful plumage during breeding season?

Given below are some behaviors strategies.

A) Fixed action pattern, complex sequence of behavior, Once released and continuous to completion, even when there is change in surrounding environment

B)  natural selection select that territorial behavior that is benefit is greater than cost 

C) Imprinting, a form of learning in which a very young animal fixes its attention on the first object with which it has visual, auditory, or tactile experience

D) Donor benefits at a cost to the recipient, the behavior is altruistic; when the recipient benefits at a cost to the donor, the behavior is selfish.
