Polar cell: - occur 60 and 90-degrees from the equator, near the north and south poles. - associated with high pressure zones and low precipitation. what is the interaction between Ferrell and Polar cell circulation?
The metric system is a system of weights and measures that was first applied in 1795 in France. Experts everywhere the world use it as the international standard to evidently communicate data. The significance are the following:
• SIMPLICITY which is the metric system is much simple than the english system because it uses a standard conversion influence for all units.
• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures.
• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures.
• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.
• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.

Answer:
Ralph is looking at a vein (likely a muscular vein).
Explanation:
Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves. This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.
Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.
