What are the 4 steps of cell signaling? While most pathways share the same basic steps of cell signaling (reception, transduction, response, resetting), there are different pathways. What are the four steps of a signal transduction pathway in order? What are the four steps of signal transduction? (1) signal molecule binds to receptor that (2) […]
Do we need oxidants?
Do we need oxidants? Oxidation can damage vital molecules in our cells, including DNA and proteins, which are responsible for many body processes. Molecules such as DNA are needed for cells to function properly, so if too many are damaged, the cell can malfunction or die. This is why antioxidants are important. Why are oxidants […]

What causes a car not to start if the battery is good?
Is radioactive decay bad?
Is radioactive decay bad? Radiation can either kill cells or damage the DNA within them, which damages their ability to reproduce and can eventually lead to cancer. When radiation is present, high energy particles pass through your body. These can collide with atoms in your body and disrupt atomic structure. What is a decay constant […]

What is the new technology in ESEM?
What is the new technology in ESEM? These problems can now be overcome, thanks to the new environmental scanning electron microscope (ESEM), which permits the imaging of wet systems with no prior specimen preparation. Which gas is used in SEM? However, the first images of wet specimens in an SEM were reported by Lane in […]
What happens to kinetic energy when velocity decreases?
What happens to kinetic energy when velocity decreases? Decreases in mass cause decreases in kinetic energy due to the aforementioned positive relationship between the two. In the case of a decrease in mass and velocity, kinetic energy must decrease because both of the determining factors decreased. Does kinetic energy increase velocity? It turns out that […]
