Answer:
A. Phototropism and geotropism are adaptations of plants that allow for survival. 
Explanation:
Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus. 
Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism. 
Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"
 
        
             
        
        
        
The statement which best explains the origin of life on Earth is that r<span>eproducing molecules evolved into living molecules by biological processes. 
RNA is the precursor of all life on Earth, and today's life descends from RNA world.

The part of the brain which is affected is reasoning center of the new brain. Drinking alcohol also decreases motor function and slow reaction time, this is why when a person is drunk, he/she may not be able to stand or walk a straight line.
Psychoactive drug or psychotropic substance is a chemical substance that acts primarily upon the central nervous system where it alters brain function resulting in temporary changes in perception, mood, consciousness and behavior.
