Nickel is classified as a “Transition Metal” which are located in Groups 3 – 12 of the Periodic Table. What […]
What is it called when you replicate a study?
What is it called when you replicate a study? Replication is a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances. What are the two types of replication psychology? At […]
What is the best frequency for a tuning fork?
How does a catalyst decrease activation energy?
How does a catalyst decrease activation energy? A catalyst can lower the activation energy for a reaction by: orienting the reacting particles in such a way that successful collisions are more likely. reacting with the reactants to form an intermediate that requires lower energy to form the product. What is difference between positive and negative […]
How might predator/prey relationships affect light pollution?
How might predator/prey relationships affect light pollution? Summary: A new study provides strong evidence that exposure to light pollution alters predator-prey dynamics between mule deer and cougars across the intermountain West, a rapidly growing region where nighttime skyglow is an increasing environmental disturbance. When the environment has reached its carrying capacity for the human population […]
What is powered by steam?
What is powered by steam? In steam. Steam power constitutes an important power source for industrial society. Water is heated to steam in power plants, and the pressurized steam drives turbines that produce electrical current. The thermal energy of steam is thus converted to mechanical energy, which in turn is converted into… How fast did […]
What is an experimental control example?
What is an experimental control example? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. Why is it important to have […]
Is nitrous acid present in acid rain?
Is nitrous acid present in acid rain? Industrial areas tend to release nitrous oxides gas, or chlorine gas or sulfurous gas into the atmosphere, when these gases combine with water from the acid rain, they are turned to nitric acid (HNO3), chloric acid (HCl) or sulfuric acid (H2SO4) respectively. Is sulphurous acid present in acid […]
How can we protect the cryosphere?
How can we protect the cryosphere? By quickly taking steps to curb emissions from cookstoves, forest burning, fossil fuel extraction and diesel transport countries could help preserve the cryosphere while at same time saving the lives and health of millions. What would happen if the cryosphere melted? Unsurprisingly, water from the current cryosphere melt is […]
What characteristics are used to identify metamorphic rocks?
What characteristics are used to identify metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What is the classification of igneous rocks based on quizlet? […]
