Scientific literacy is the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity.
The origin of life on Earth is a set of paradoxes. In order for life to have gotten started, there must have been a genetic molecule something like DNA or RNA capable of passing along blueprints for making proteins, the workhorse molecules of life. But modern cells can’t copy DNA and RNA without the help of proteins themselves. To make matters more vexing, none of these molecules can do their jobs without fatty lipids, which provide the membranes that cells need to hold their contents inside. And in yet another chicken-and-egg complication, protein based enzymes, encoded by genetic molecules, are needed to synthesize lipids.
Sensation
<h3>How does sensory transduction work?</h3>
Action potentials, or electrical impulses, are nearly entirely how the brain functions. (This is not the complete picture; there are more chemical components, but for the sake of this response, we will disregard them.) How to turn an universe of non-electrical inputs into a signal that the brain can understand is the issue at hand. Therefore, we have transducers—things or structures that can convert various forms of energy into electrical impulses that our brains and, incidentally, electronics can use.
On their cell membranes, sensory cells express a variety of chemicals. These structures serve a range of purposes, including supporting tissue integrity, acting as receptor sites, and carrying out signaling processes. The majority of these receptors react to chemical stimuli, such as those that adrenaline binds to in the heart, those that muscles express in the form of insulin and glucagon receptors, and so on. Some of these structures will, however, react to outside forces.
