Carbon-14 is the radioisotope that is used to determine the age of once-living organisms. Radioactive dating is a technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material. The mostly used radioisotope is carbon-14, because may rocks and organisms contain this radioisotope.
Answer:
As the blood pressure in each of the blood vessels is measured, it can be predicted to be lowest in the capillaries.
Explanation:
Options for this question are:
- <em>Artery.</em>
- <em>Arteriole.</em>
- <em>Capillaries.</em>
- <em>Venule.</em>
- <em>Vein.</em>
Once the blood leaves the heart, it is distributed in a network of arterial vessels -arteries and arterioles- that bridge the venules and veins through the capillaries. Blood pressure depends on the pumping strength of the heart and the force that blood produces on the vessel walls. There is a marked difference between arterial and venous pressure. Some conclusions can be drawn from this:
- <em>Blood pressure is higher the closer the vessel is to the heart.
</em>
- <em>The larger the vessel, the more blood is contained and the more blood pressure is recorded.
</em>
Based on this, it can be deduced that the blood vessels with the lowest pressure are the capillaries, with very thin walls and where gas and nutrients or metabolites enter and leave the vessel.
The question gives an answer, but does not explain why.
