Active transport is the process in which substances are absorbed against a concentration gradient, i.e. from a lower to a higher concentration.
Atoms are electrically neutral because they have equal numbers of protons positively charged and electrons negatively charged.
Active:requires the assistance of a carrier protein, also requires energy
Passive:does not require energy is also movement of ions and other atomic and other molecular substances.
It's from the Hawaiian language and means the words "shiny, glassy surface, and smooth". The type of lava you want to know is Pahoehoe lava. Lava tubes are usually floored with it.
Hope this helps! :-)
The answer to this question would be letter C because a dependent variable depends on the project. For instance, If there is a scientist trying to see which plant will grow the fastest just using water. The plant depends on the water. hope this helps!
