Explanation: Mark me brainly
Answer:
A) Reticular activating system
Explanation:
The reticular activating system is a complex network of neuron present in the brainstem of the brain.
The reticular system is involved in many functions of the brain like the flight or fight response, the sleep and awake awareness and the elimination of the unwanted and unimportant stimuli of the person.
In the given question, since the person, while studying unconsciously avoids the rustling of paper and the pressure of the clothes which is performed by the reticular system in the brain.
Thus, Option-A is correct.
Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
Adrenaline is the hormone secreted
Prophase I would be correct...
