Explanation:
because the pressure exerted by artery is more than that of vein due to its narrow lumen and thick walls...causing it difficult to clot.
Answer:
It is explain about how is the cell division.and what are the examples for it.
Thera are two type of cell division.
1. Mitosis.
2.Meiosis
Answer:
At a thermoneutral ambient temperature, cooling either thermode increased oxygen consumption. In a cold environment, cooling either thermode increased the rate of oxygen consumption more than at a thermoneutral temperature. Heating either thermode tended to decrease oxygen consumption in a cold environment. 3.
Explanation:
Answer:
Using the concept of relative dating
Explanation:
Scientists use the concept of relative dating principles to determine when the Great Oxidation event occurred.
Relative dating is the process of placing ancient event in their proper time sequence based on the relationship between rock lithologies.
- An event like the great oxidation will have significant chemical, biological and physical effect on the rock units.
- Rocks that form during this period in time will have very unique chemical signatures.
- Therefore, by studying these rocks, the age of the layer can be fixed when we compare it to the standard geological column.
