Study the list of sentences. i. if plants are placed under a green light, then they will stay the same height because they will not grow. ii. if plants are left in a dark room, then they will increase in height because plants do not need light energy to grow. iii. if plants require carbon dioxide to grow, then plants exposed to more carbon dioxide will grow more quickly. which option is true about whether the sentences are correctly formatted hypotheses? a )sentence ii is not a correctly formatted hypothesis because it is factually inaccurate. b )sentence i is not a correctly formatted hypothesis because it does not explain why green light might affect plant growth. c )all of the sentences are correctly formatted hypotheses because they all include “if … then …” statements. d )sentence iii is not a correctly formatted hypothesis because it does not use the word “because.”

Astudent wants to test if a bean plant will grow taller under green light than under sunlight. select fror the drop-down menu the correct step of the scientific method that each statement describes two identical bean plants are grown next to each other. they receive the same amount of water and sunlight. one plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. measurements of the bean plants' heights are recorded every day for two weeks the student writes a lab report detailing the experimental procedure and results the bean plant grown under the green filter will grow taller than the bean plant grown under unfiltered sunlight green light makes plants grow taller the measurements show that the plant grown in natural sunlight grew taller than the green-filtered plant so green light does not make plants grow taller
