Where does the dependent variable go in a hypothesis statement? A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. It may take the form of a cause-effect statement, or an “if x,…then y” statement. The cause is called the independent variable; and the effect is […]

Is the cell membrane fully permeable? The cell wall is fully permeable to smaller molecules with the size of 30-60 kDa. The membrane is selectively permeable and controls the movement of the substance into and outside the cell. Functions include protection from the external environment. Do animal cells have a selectively permeable membrane? Cell Membranes. […]

What is the substance that gets dissolved called? solutes What happens when the temperature of a saturated sugar solution is increased? When the Temperature of a Saturated Sugar Solution is Increased, It Would Become Unsaturated Due to Increase in Solubility of the Solute. What do you observe when you heat a saturated solution of sugar? […]

What are Class 1 wiring methods? A class 1 circuit is the portion of the wiring system between the load side of the overcurrent protection device (OCPD) or the power-limited supply and the connected load. For example, Class 1 power-limited circuits are supplied by a power supply with an output that does not exceed 30 […]

Can a sense of rhythm be learned? You can improve your sense of rhythm by paying attention to certain things in music. Most popular forms of music rely on only a few time signatures, so if you know what they are and how to count them, you will have covered a lot of ground already […]

What is wrong with the evolution? Evolution could be falsified by many conceivable lines of evidence, such as: the fossil record showing no change over time, confirmation that mutations are prevented from accumulating in a population, or. observations of organisms being created supernaturally or spontaneously. Why evolution is possible? Populations evolve. Because individuals in a […]

What are the impacts of recreational fishing on marine ecosystems? Recreational fishing has its biggest impact on marine debris, overfishing, and fish mortality. Release mortality in recreational fisheries is the same as the impacts of bycatch in commercial fisheries. What are the impacts of commercial fishing? DEGRADED ECOSYSTEMS When too many fish are taken out […]

Can a motion be Thirded? In this process, someone proposes a motion, and if someone else seconds it, the motion may be discussed and voted on. If there is no seconder, the motion isn’t even considered. There is no requirement for a ‘second seconder’ or a ‘thirder’, and no formal term for such a role. […]

When weather predictions are incorrect What is the most likely cause? 1) When weather predictions are incorrect, what is the most likely cause? Small differences in models can lead to large differences in complex systems. Measurements of the initial conditions may have been very inaccurate. The person predicting the weather may have had a bias. […]
