The root of a huge tree causes cracks in a rocky surface. ---> biological Weathering.

Part of a cliff breaks and falls due to waves. > mechanical weathering

Acid rain reacts with calcite present in limestone---> chemical weathering

Explanation:

The root of a huge tree causes cracks in a rocky surface is the example of biological Weathering because in this weathering living organism is involved.  Part of a cliff breaks and falls due to waves of water is the example of mechanical weathering because water enters the small pores of rocks and formed cracks when expands.  Acid rain reacts with calcite present in limestone is a chemical weathering because acid present in rain water is responsible for the degradation and breakdown of rocks.

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
