Explanation:
The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.
Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.
- Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
- Tool man also grazed the surface of the earth just a few thousands to a million years.
- We are able to find their fossils in rocks because they have lived in some certain geologic periods.
- Here we are using the fossils to date the rock and this is called relative dating

Answer:
Option c. cause pooling of the blood and decreased venous return to the heart
Explanation:
The ACE inhibitors increases the diameter of the blood vessels (vasodilation) that improves the flow of blood. This reduces the work load on the heart. At the time of heart failure, a substance called angiotensin is released. This angiotensin formation is blocked by the ACE inhibitors. Angiotensin is involved in narrowing the blood vessels.
The ACE cause pooling of the blood and decreased venous return to the heart. The ACE inhibitors causes vasodilation that allows decrease in blood pressure. So, there is no increase in arterial pressure, aldosterone and loss of volume. Thus, option C is correct.
