Answer:
involve calcium voltage-gated channels
Explanation:
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.
Answer:
C.
Explanation:
C. Warm and shallow, even though they can be found in deeper water they do better the more shallow the water is. They also live in tropical places and in salt water. They can not survive in fresh water or cold water for very long.

Lymph is the excess blood plasma after it is filtered from interstitial fluid, when the interstitial fluid is formed. From the circulation system, after filtration, lymph is comes into to the Lymphatic system.
The Lymphatic system with its tubular vessels, is an open system. It conducts lymph between various parts of the body. It provides a route for the excess interstitial fluid to be returned back to blood.
On the other hand, Our cardiovascular system - responsible for circulation of blood - is a
closed system. Blood never leaves the veins, arteries, and capillaries.
