Does PTSD show up on a brain scan? Brain scans can be very helpful in getting a PTSD diagnosis. Two studies published by the research team at Amen Clinics showed that brain SPECT imaging is able to differentiate PTSD from TBI with a 94% accuracy rate. Is PTSD considered a permanent disability? Post-traumatic stress disorder […]
Is torque a type of moment?
How does oxygen enter plant cells?
How does oxygen enter plant cells? In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration”. What triggers stomata to open? Stomata are […]
Is it safe to use a microwave that has peeling paint inside?
Is it safe to use a microwave that has peeling paint inside? If the coating is actively flaking or paint is peeling anywhere inside the oven cavity (including under the turntable) discontinue the use of the microwave and replace it. The microwave is not repairable. The inadvertent ingestion of small amounts of peeling coating does […]
Why are fossils so important?
Why are fossils so important? Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited. What are the five types of fossils? Five different types of fossils […]
Are self-driving cars a good idea?
Are self-driving cars a good idea? Self-driving cars could be of huge benefit to the environment. Part of the reason cars cause so much air pollution is traffic gridlock in highly congested areas. The efficiency of self-driving cars, in addition to the possibility of a future without any gridlock or traffic stops, will cut down […]
What is perturbation technique?
What is perturbation technique? A mathematical technique to eliminate linear terms in an equation in order to retain the nonlinear (turbulence) terms. Variables such as potential temperature (θ) or velocity (U) can be partitioned into mean (slowly varying) and perturbation (rapidly varying) components. Why do we use perturbation? Perturbation is used to find the roots […]
How do we measure distance?
What is the resistor value?
Is needed to start a chemical reaction?
Is needed to start a chemical reaction? Chemical reactions won’t begin until the reactants have enough energy. The energy is used to break the chemical bonds of the reactants. Then the atoms form the new bonds of the products. Activation Energy is the minimum amount of energy needed to start a chemical reaction. What 3 […]
