What would happen if Gulf Stream stopped? A weaker Gulf Stream would mean higher sea levels for Florida’s east coast. It could lead to colder winters in northern Europe (one reason many scientists prefer the term climate change to global warming). Can the entire ocean freeze? Yes, all the oceans on the planet could freeze […]
What are the examples of magnetic effect of electric current?
What are the examples of magnetic effect of electric current? When electric current passes through a wire, the current-carrying wire behaves like a magnet. This is called the magnetic effect of current. The magnetic effect of current is utilised in making electromagnets, electric bells, telephone instruments, electric fans, electric motors, loudspeakers and toys etc. Which […]
What type of chemical reaction is KCl?
What type of chemical reaction is KCl? The type of chemical bond that holds together the potassium and chlorine atoms in a potassium chloride molecule is an ionic bond. The electronegative chlorine atom accepts the 4s electron belonging to the potassium atom and an ionic attraction arises between the resulting K+ and the Cl– ions. […]
What viruses are oncogenic?
What viruses are oncogenic? Oncogenic DNA viruses include EBV, hepatitis B virus (HBV), human papillomavirus (HPV), human herpesvirus-8 (HHV-8), and Merkel cell polyomavirus (MCPyV). Oncogenic RNA viruses include, hepatitis C virus (HCV) and human T-cell lymphotropic virus-1 (HTLV-1). What is silent gene? Silent genes are generally found in more compact regions of chromatin, termed heterochromatin, […]
How are chemical sediments are formed?
How are chemical sediments are formed? Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. This is a common way for chemical sedimentary rocks to form and the rocks are commonly […]
What setting do you use on a multimeter to test a car battery?
How do you memorize music notes by ear?
What is the difference between mass number and relative atomic mass?
What is the difference between mass number and relative atomic mass? Atomic mass is also known as atomic weight. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element’s isotopes. The mass number is a count of the total number of protons and […]
What can speed up diffusion?
What can speed up diffusion? The rate of diffusion Factor How the factor affects the rate of diffusion Concentration gradient The greater the difference in concentration, the quicker the rate of diffusion Temperature The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly What does […]
What natural landforms are born when two tectonic plates collide?
What natural landforms are born when two tectonic plates collide? Collisions of two plates may create everything from fold mountains to oceanic trenches; divergent plates come marked by mid-ocean ridges. Why do earthquakes happen at subduction zones? Why do so many earthquakes originate in this region? The belt exists along boundaries of tectonic plates, where […]
