What is controlled variable example? Examples of Controlled Variables Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment. What are […]
What level of CO2 ppm is dangerous?
What level of CO2 ppm is dangerous? This could occur when exposed to levels above 5,000 ppm for many hours. At even higher levels of CO2 can cause asphyxiation as it replaces oxygen in the blood-exposure to concentrations around 40,000 ppm is immediately dangerous to life and health. What happens when CO2 reaches 1000 ppm? […]

What is the pOH if the pH is 3?
What are benthic ecosystems?
What are benthic ecosystems? Page 1. The benthic zone is the ecological region at the lowest level of a body of water. It starts at the shoreline and continues down until it reaches the floor, encompassing the sediment surface and sub- surface layers. Although this zone may appear barren, it plays a vital role in […]
What is the impact of carrying capacity on ecosystems?
What is the impact of carrying capacity on ecosystems? Carrying capacity is the largest population size that an ecosystem can sustainably support without degrading the ecosystem. To a certain extent, population numbers are self-regulating because deaths increase when a population exceeds its carrying capacity. Why is carrying capacity important in ecosystems? When an ideal population […]
How many joules is 1500 watts?
Are T Rex male or female?
Are T Rex male or female? Oddly, T. Rex appears to have been sexually dimorphic in another way: many paleontologists now believe that the females of this species were significantly larger than the males, over and above the size of their hips. What this implies, in evolutionary terms, is that female T. How tall is […]
When white light passes through a prism What color is bent most?
When white light passes through a prism What color is bent most? violet light Why can a prism break white light up into different colors quizlet? Explain how prism separates white light into the colors of the spectrum. As white light passes through a prism, shorter wavelengths refract more than longer wavelengths and the colors […]
What prevents an atom from collapsing?
What prevents an atom from collapsing? The balance of kinetic and potential energy in an atom is what keeps its electrons from collapsing into the nucleus. Can atoms collapse? The nuclei of atoms become unstable when the repelling forces of the protons cannot be balanced by the number of neutrons in the nucleus. It then […]
