Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
Honestly I'd say a biologist studying the liver in mice, would figure out a drug to help the liver metabolize drugs and detoxify chemicals. I'd think they would figure out a way to prolong life by increasing liver health, and help remove Bile buildups that can occur. Both in human and in mice.
Active transport is a process requiring energy in which a substance crosses the cell membrane. In a resting neuron, there are positively charged sodium ions outside of the cell, and negatively charged potassium ions in the cell. When the neuron fires, depolarization occurs=> the positive ions are forced in and negative ions are forced out by means of active transport. When the neuron is done firing, the ions are forced back into their original position inside or outside of the cell by active transport.
