I'll give brainlist!! Please helppp‼️‼️ 1.How many years does the table include, from the first species to the last?

2.From the fossil evidence shown, how did the forefeet change over time?

3.From the fossil evidence shown, how did the skills change over time?

4.How might the environment in which each of these species lived have affected the evolution of horses?

1: 50 million years

2: The forefeet changed over time by the bones merging into one to create the hoofed feet that we are used to today.

3: Their teeth and skull changed over time to better fit the environment and food they fed on. Their feet and hight changed based on the physical requirements of the environment like walking across dense forests vs open prairies and how they had to move to access food.

4: The environment affected the way the horses evolved because they had to evolve to better fit and survive/thrive the new environments they lived in.

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
