I believe that what is meant with the phrase "older explanation" is none other that superstition. Therefore, I will give you one superstitious belief which is now explained by science.
In Southeast Asia, people used to believe that St. Elmo's fire appears in remote areas because a bloody battle occured in that place leaving disembodied souls of the dead wandering there in the night and even in sunshine!
For generations, many people believed that this is a fact and some even say that these apparitions are diabolical or demonic in nature. So often, caution is advised to people whenever a ball of fire appears out in the open.
However, recent breakthroughs in the 21st century helped scientists to explain this mysterious phenomena. They found out that St. Elmo's fire is actually plasma, nothing special. Now, plasma is considered one of the states of matter! But mind you, it still does not explain why St. Elmo's fire seems to have a mind of its own!
I don't know if this is the answer you're looking for but "Transporters" move molecules across membranes. Such as channel proteins and carrier proteins
Biology is an interdisciplinary study, which means that it relies on and depends on many other studies. You cannot always study biology without paying attention to other sciences as well, because they are so interconnected. For example, history and biology are connected - in biology, you study evolution, which is how beings evolved through history. Also, physics is important to biology - various chemical process that take place in both humans and other living beings is what both chemistry and biology study. Geography and biology are also closely-knit, given that geography has to do with the Earth and its ground on which plants and other living beings exist.
Hope this helps! :)
