Why are humans so negative?
Why are humans so negative? The human brain has a natural tendency to give weight to (and remember) negative experiences or interactions more than positive ones—they stand out more. Psychologists refer to this as negativity bias. “Our brains are wired to scout for the bad stuff” and fixate on the threat, says psychologist and author […]
What are the three coefficient of thermal expansion?
What are the three coefficient of thermal expansion? This equation shows the relationship between α is the linear expansion, β is the superficial expansion, is volume expansion. These three coefficients of expansion for a given solid are not constant because these values totally depend on the temperature. How are the three coefficients of expansion? Expansion […]
What does listening to 528 Hz do?
What does listening to 528 Hz do? According to the current study, sound waves with 528 Hz frequency in 100 dB intensity induce testosterone production in brain by enhancing StAR and SF-1 and reducing P450 aromatase gene expression. Frequency of 528 Hz also reduces total concentration of reactive oxidative species in brain tissue. How many […]
What are the four principles of stratigraphy?
What are the four principles of stratigraphy? Steno’s laws of stratigraphy describe the patterns in which rock layers are deposited. The four laws are the law of superposition, law of original horizontality, law of cross-cutting relationships, and law of lateral continuity. Nicolaus Steno was a 17th-century Danish geologist.

What are the three roles of bacteria? In summary, bacteria are single-celled microbes without a nucleus. Bacteria play many roles in our ecosystem. Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria. What are […]
What happens if the brain does not maintain homeostasis?
What happens if the brain does not maintain homeostasis? What happens if there’s disruption? If homeostasis is disrupted, it must be controlled or a disease/disorder may result. Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of […]
How do plants and animals get the energy they need?
How do plants and animals get the energy they need? Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called “photosynthesis”. Plants get their energy in form of starch whereas animals get it in form of glycogen. In which light photosynthesis is maximum? […]
What does the slope of displacement time graph gives?
What does the slope of displacement time graph gives? A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is […]
How accurate are home DNA testing kits?
How accurate are home DNA testing kits? Since most of us aren’t geneticists, it can seem daunting. But here’s the bottom line: “Are home paternity tests accurate?” Yes! You can expect to see the exact same results for a home paternity test as you would for a legal, court-admissible test if all DNA samples submitted […]
