What can eDNA tell us?
What can eDNA tell us? eDNA can tell scientists which species the parasites have been feeding on, which can tell scientists if rare species are present in the area. eDNA can also be used as an early-warning system to identify invasive species as they spread into new environments. What is eDNA Metabarcoding? Environmental DNA (eDNA) […]
Why do seismic waves speed up?
Why do seismic waves speed up? Seismic waves travel fast, on the order of kilometers per second (km/s). Temperature tends to lower the speed of seismic waves and pressure tends to increase the speed. Pressure increases with depth in Earth because the weight of the rocks above gets larger with increasing depth. Where do seismic […]
What is the function of electrical grid?
What is the function of electrical grid? The electrical grid is a complex network of electrical generators (i.e., power plants) and transmission and distribution lines that dynamically responds to shifts in electrical supply and demand to make sure electricity is always supplied reliably. Who controls the electricity grid? The US grid is a complex network […]
What is the difference between normal boiling point and boiling point of a liquid group of answer choices?
What is the difference between normal boiling point and boiling point of a liquid group of answer choices? The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it. The normal boiling point of a liquid is the temperature at which its […]
What happens to the current in a circuit if the resistance is increased group of answer choices?
What happens to the current in a circuit if the resistance is increased group of answer choices? What happens to the current in a circuit if the resistance is increased? The correct answer is: The current decreases. The unit of measurement for the charge a capacitor can store is called a Joule. When comparing two […]
What is the inductance unit?
What is the inductance unit? Henry, unit of either self-inductance or mutual inductance, abbreviated H, and named for the American physicist Joseph Henry. One henry is the value of self-inductance in a closed circuit or coil in which one volt is produced by a variation of the inducing current of one ampere per second. What […]
How do you tell if a mountain was a volcano?
How do you tell if a mountain was a volcano? For a landform to qualify as a mountain, it must rise for over 600 meters above the surrounding area. However, not all volcanoes have higher elevations than the surrounding area. Volcanoes may form part of mountain ranges. How are rocks at the top of a […]
How do I increase the heat in my fireplace?
Which is the main light absorbing pigment for photosynthesis?
Which is the main light absorbing pigment for photosynthesis? Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly. In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. What is carbon fixation and how does it relate to photosynthesis? Carbon fixation is the process by […]
