Which theory of emotion is best? In psychology, emotion is often defined as a complex state of feeling that results in physical and psychological changes that influence thought and behavior. The James-Lange theory is one of the best-known examples of a physiological theory of emotion. What is the correct sequence of events according to the […]
What is the role of heat and pressure to metamorphism?
What is the role of heat and pressure to metamorphism? Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions. […]
Is Earth losing its atmosphere?
Is Earth losing its atmosphere? A pair of researchers from Toho University and NASA Nexus for Exoplanet System Science has found evidence, via simulation, that Earth will lose its oxygen-rich atmosphere in approximately 1 billion years. What would happen if we lost gravity? If the Earth’s gravity did just suddenly disappear we would no longer […]
What would happen if Earth had a tilt of only 5?
What would happen if Earth had a tilt of only 5? An axial tilt of only 5 degrees, however, would mean that seasonal variations would be minimal below about 80 degrees of latitude. Without these seasonal variations, the global climate would be much more uniform, but this would also cause devastation to most of the […]
Can Methanol be broken down by a chemical change?
Can Methanol be broken down by a chemical change? Which substance can be decomposed by a chemical change? Reason: when it said a substance, think of the matter chart. Substances can be broken down to a compounds or elements. Beryllium, Boron, and Magnesium are elements and Methanol is a compound which can be chemically change. […]
Who is the father of LED bulb?
Who is the father of LED bulb? Nick Holonyak Who invented the first LED light? Shuji Nakamura What purpose do LED lights serve? LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which […]
Which metal is used for cathodic protection?
Which metal is used for cathodic protection? The simplest method to apply cathodic protection is by connecting the metal to be protected with another more easily corroded metal to act as the anode. Zinc, aluminium and magnesium are the metals commonly used as anodes. What is the difference between sacrificial anode and impressed current? The […]
How do you calculate ploidy?
How do you calculate ploidy? Ploidy can be assessed either by chromosome number or by flow cytometry using the DNA index (DI), the ratio of fluorescence in leukemic blasts compared to normal cells. Normal diploid cells have 46 chromosomes and a DI of 1.0, hyperdiploid cells have higher values, and hypodiploid cells lower. What does […]
What happens if u eat chalk?
What happens if u eat chalk? Chalk is considered non-toxic in small amounts. If large amounts are eaten, it can be irritating to the stomach and cause vomiting. Chalk can be a choking hazard for very young children. CAUTION: Eating pool or billiard chalk can be different than school and blackboard chalk because it may […]
How did Newton figure out gravity?
How did Newton figure out gravity? The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest. Did Newton really discover […]
