What is a federally controlled water?
What is a federally controlled water? Federally controlled waters are waters on which vessels must observe federal requirements, including visual distress signal requirements. These waters include: Bodies of water connected directly to one of the above, up to a point where the body of water is less than two miles wide. What must be on […]
What are the three categories of adaptation?
What are the three categories of adaptation? There are three different types of adaptations: Behavioural – responses made by an organism that help it to survive/reproduce. Physiological – a body process that helps an organism to survive/reproduce. Structural – a feature of an organism’s body that helps it to survive/reproduce. What is a person who […]
What is an uncomfortable level of humidity?
What is an uncomfortable level of humidity? Forecasters watch the dew point, not relative humidity, because hot air can hold more moisture than cool air. At 90 degrees, we feel uncomfortable at dew points of 65-69 degrees. But the RH may be only 44 – 52 percent (half the atmosphere’s capacity). Dew points above 70 […]
How do most Heterotrophs directly contribute to the carbon cycle?
How do most Heterotrophs directly contribute to the carbon cycle? Heterotrophs acquire the high-energy carbon compounds from the autotrophs by consuming them, and breaking them down by respiration to obtain cellular energy, such as ATP. Gas exchange through the atmosphere and water is one way that the carbon cycle connects all living organisms on Earth. […]

How do you calculate accelerating potential?
How do you calculate accelerating potential? The kinetic energy of an electron accelerated through a potential difference of V volts is given by the equation: ½ mv2 = eV where e is the electron charge (1.6×10-19 C) [You must be given the electron charge and Planck’s constant in order to answer this question]. What is […]
