What are the two circuits of the cardiovascular system? What does it mean to say that the cardiovascular system is a closed syst
maksim [4K]

Answer:

The two circuits of the cardiovascular system are: Pulmonary Circuit and Systematic Circuit. The pulmonary circuit is shorter than the systemic and is responsible for carrying deoxygenated blood to the lungs from the right atrium, for oxygenation. The systemic circuit is longer and leaves the aortic artery, carrying oxygenated blood throughout the body and nutrients for survival. If less blood were pumped into the systemic circuit, this amount would not be sufficient to compensate for the organism's needs, with the corresponding consequences that this would entail.  

It is said that the cardiovascular system is a closed system because blood travels inside a network of blood vessels without leaving them.

It´s a type of reproduction practiced by Achaea and bacteria which are single-celled organisms.

How would you make 2.5 liters of an aqueous solution containing 150mM Tris (the MW of Tris is 120g/mole)? (Hint: Do the necessar
lisabon 2012 [21]

Answer:

45 g of the solid Tris will be dissolved in 2.5 liters of water.

Explanation:

Recall that:

<em>Number of moles  = molarity x volume</em>

Hence, number of moles of Tris present in 2.5 liters, 150 mM solution:

= 150/1000 x 2.5 = 0.375 moles

Also, recall that:

<em>No of moles of substance = mass/molar mass.</em>

Hence, mass of 0.375 moles substance:

= no of moles of the substance x molar mass of the substance.

= 0.375 x 120 = 45 g.

Therefore, in order to prepare 2.5 liters, 150 mM of an aqueous solution of Tris, 45 g of the solid Tris will be dissolved in 2.5 liters of water.
