What should it show about the relationship between oxygen and energy production?(1 point) Responses oxygen is used to split glucose molecules, releasing energy oxygen is used to split glucose molecules, releasing energy oxygen combines with glucose molecules, forming ATP and water oxygen combines with glucose molecules, forming ATP and water oxygen is a waste product that is released during energy production oxygen is a waste product that is released during energy production Question 16 Which is the byproduct of lactic acid fermentation(1 point) Responses pyruvic acid pyruvic acid lactic acid lactic acid carbon dioxide carbon dioxide Question 17 During cellular respiration, energy is released. What would a model need to show to accurately demonstrate that matter is rearranged and energy is conserved in the process?(1 point) Responses Visuals showing that more energy is produced than consumed when water and carbon dioxide are combine Visuals showing that more energy is produced than consumed when water and carbon dioxide are combine oxygen molecules combining with carbon atoms to create new substances without changing the mass oxygen molecules combining with carbon atoms to create new substances without changing the mass glucose and oxygen breaking into carbon dioxide and water, mass remains the same, energy is released glucose and oxygen breaking into carbon dioxide and water, mass remains the same, energy is released Question 18 What type of molecule is added to ADP to make it a higher energy molecule that can carry energy in cells?(1 point) Responses oxygen atom oxygen atom amino group amino group phosphate group phosphate group Question 19 Scientists develop a genetically modified plant species that has a nonfunctional protein. The protein is necessary for the plant to use nitrogen. The species has a single mutation in a gene. What does this tell us about the relationship between DNA and proteins?(1 point) Responses Proteins are not related to DNA Proteins are not related to DNA Changes in DNA can affect protein function Changes in DNA can affect protein function Mutations in DNA are always harmful to organisms Mutations in DNA are always harmful to organisms Question 20 The mutation shown in the sequence can be categorized as which type?
