Problem: Process: - Carbon dioxide from the air passes through small pores (holes) in the leaves - These pores are called stomata - Water is absorbed by the roots - It passes through vessels in the stem on its way to the leaves - Sunlight is absorbed by a green chemical in the leaves. Question: suppose "the roots cant absorb water" happens, how will it affect leaves absorbed sunlight. - A: more - B: less - C: no effect

A: B

Problem: Process: - Electrical signals in the brain travel through nerves to muscles - Two types of proteins exist in filaments in the muscles - The filaments move when the brain instructs them to - The motion of the filaments cause the muscle to shorten and contract - Opposing pairs of muscles exist in order to provide the necessary range of motion. Question: suppose there is no filaments in the body happens, how will it affect muscle movement is caused by filaments. - A: more - B: less - C: no effect

A: B

Problem: Process: - Green is a color that gathers sunlight easily - Sunlight is gathered by the leaves of the plant - The sunlight is broken down into glucose through photosynthesis - The glucose travels the plant - The plant uses that glucose as energy to grow. Question: suppose the plants grow healthier happens, how will it affect more sunlight is collected by the leaves of plants. - A: more - B: less - C: no effect

A: A

Problem: Process: - Stars burn mass - The star burns until it runs out of fuel - The star can no longer support its weight - The layers of hydrogen press down on the core - The core gets smaller and smaller under the pressure - The pressure causes gravity to get stronger - The gravity becomes so powerful that nothing can escape it - Anything that gets close to it, is drawn into it by its gravity - Light is drawn into it - Light can not escape - Question: suppose fewer stars burn happens, how will it affect less light can escape. - A: more - B: less - C: no effect

A:
B
