Students are presented with two different diagrams showing the use of gases in cellular respiration and photosynthesis and asked to explain which is correct.
1
• Student A says model A is correct because oxygen is a product of
photosynthesis and a reactant for cellular respiration
Student B says model B is correct because carbon dioxide is a product of
photosynthesis and a reactant for cellular respiration
Which student is correct and how could the model be improved?

answer;

-vessels in the chest

the diagnosis of angina pectoris literally means "vessels in the chest"

explanation;

-angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease.it is the chest pain due to an inadequate supply of oxygen to the heart muscle. the pain is typically severe and crushing, and it is characterized by a feeling of pressure and suffocation just behind the breastbone.

agina pectoris is caused by reduced blood flow to your heart muscle. the blood carries oxygen, which the heart muscle needs to survive. when the heart muscle isn't getting enough oxygen, it causes a condition called ischemia
