Answer:
B
Explanation:
Hans Selye is regarded as the founder of the theory of stress.
He developed the general adaptation syndrome (GAS) which describes how the body reacts to stress.
The stages of GAS are :
alarm reaction - flight or fight response to stress
resistance - continued exposure to stress leads to higher metabolic response to offset the stress
exhaustion - continued exposure to stress can negatively affect the body and lead to health problems
Hans made this discovery in the 1930s after studying the response of rats after the injection of hormones into them. He compared their cortisol and blood sugar levels in rats before and during the experiment.
He concluded that it was the stress that caused the rat to become ill and die
It is True, oxidation is associated with an increase in oxidation number.
An oxidation; reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Oxidation states are typically represented by integers which may be positive, zero, or negative.
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.
