Answer:
I'm pretty sure the answers for this is D, C, and B.
Answer:
Figure 3
Explanation:
A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:
- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.
- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.
- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.
- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.
The correct answer would be stress tests. These are performed to assess the adequacy of the amount of oxygen getting to the heart muscle during exercise and at rest. With this, the absence or presence of a heart disease can be indicated. This is a common procedure done in Cardiography and Cardiovascular Monitoring Services. During this test, the patient is asked to do exercises usually using a treadmill while the patient is hooked on an EKG or electrocardiogram machine. As one exercises, the doctor would monitor the heart rate reading the systole and the diastole. There are also imaging tests to be able to capture pictures of the blood flow in the heart.
