Answer:
Blood flows from the right atrium into the right ventricle through the open tricuspid valve, and from the left atrium into the left ventricle through the open mitral valve
When charged amino acids within the interior of a protein attract, they form structure like salt bridges are are significant in determining the precise shape of the protein. This is because they attract one another strongly as opposed to the same charged molecules in a polar solvent like water.
There are many species that might go extinct. The one most endangered: White rhinos, with less than 100 in their population. To help these animals, people fund programs like the WildLife foundation. Today, with technology, we haven't had the time to make a change, these people work hard to make sure these animals get proper care and love. :)
Hope that helps!
