What does the dashed line separating the two sides represent? What does the dashed line in the beaker separating the two sides represent membrane potential? Explanation: Membrane Potential: A gradient is membrane, through which the different molecules move from one portions of the body or system into the another. What is an example of osmosis […]
What are the negative effects of gamma rays?
What are the negative effects of gamma rays? The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer. How can we reduce exposure to gamma rays? […]
Do birds feel earthquake while flying?
Do birds feel earthquake while flying? Birds and animals “feel” things in more dimensions than humans do. Birds for example are very sensitive to magnetic fields. Earthquakes being tectonic activity, I can’t see how it won’t have small impact on the earth’s magnetic field in the region. This could in turn be felt by the […]
How the mind and body are connected?
How the mind and body are connected? The brain and body are connected through neural pathways made up of neurotransmitters, hormones and chemicals. These pathways transmit signals between the body and the brain to control our everyday functions, from breathing, digestion and pain sensations to movement, thinking and feeling. What three levels did Plato say […]
Do speed radar guns take pictures?
Do speed radar guns take pictures? Speed guns do not capture any images, unlike the Truvelo and ‘Long Ranger’ cameras, that can capture a driver’s face. What happens if you get caught with a radar detector? If you’re caught using radar jammers, you’ll likely end up with an expensive fine and also confiscation of the […]
Which surface has the most amount of friction?
Which surface has the most amount of friction? Rougher surfaces have more friction between them than smoother surfaces. That’s why we put sand on icy sidewalks and roads. You can’t slide as far across ice with shoes as you can on the blades of skates (see Figure below). The rougher surface of the soles of […]
What are the similarities between an element and a compound?
What are the similarities between an element and a compound? On first glance, elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances. What do elements and […]
What is the cleanest burning fossil fuel?
What is the cleanest burning fossil fuel? natural gas What can fossil fuels be replaced with? According to the National Aeronautics and Space Administration (NASA), nuclear power is the most effective substitute to challenge fossil fuels for future energy consumption. Compared to coal, gas, oil, and ethanol, nuclear power produces almost negligible adverse climate effects. […]
Who made the HR diagram?
Who made the HR diagram? Ejnar Hertzsprung What is the biggest difference between a star and a protostar? The fundamental difference between a protostar and a star is that the latter has nuclear fusion as its energy source and the former does not. The birth of stars is a battle between gravity and radiation pressure. […]
