Sample A most likely came from the left ventricle, as this is the portion of the heart that receives freshly oxygenated blood to be pumped to different parts of the body. Oxygenated blood is blood that has had oxygen bounded to it by hemoglobin (a pigment made of iron found in red blood cells). The oxidation of this blood by the iron in the hemoglobin gives it the RBC bright red look. This blood containing the bright RBCs in transported to the left ventricle from the lung, after which it is spread throughout the body. Hence, in normal conditions of the heart, the Sample A most likely came from the left ventricle.
The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.
There are two hydrogen atoms in a molecule of water.
Given the information available to us through the image provided, we can see that the rate at which Claire's small intestine breaks down the protein, lipids, and carbohydrates is lower than that of a healthy dog.
<h3>What does the graph tell us?</h3>
- The graph shows Claire's enzyme activity using a yellow line.
- The red line shows us a healthy dog.
- In each graph, the yellow line is lower than the red, indicating that Claire's enzyme activity is lower than normal.
Therefore, given that the graphs represent claire's ability to break down these substances using a yellow line that appears to be lower than the red line representing a healthy dog through each substance, we can confirm that Claire breaks them down at reduced rates.
