Do proteins store and transmit genetic information? No, proteins do not store genetic information or transmit to the next generation. What store and transmit genetic information? Nucleic acids are polymers that store, transmit, and express hereditary (genetic) information. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores and […]
Which is older intrusion or extrusion?
Which is older intrusion or extrusion? Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. There, the magma cools and hardens into a mass of igneous rock called an intrusion. An intrusion is always younger than the rock layers around and beneath […]
Why is graphite dangerous?
Why is graphite dangerous? Graphite is a form of pure carbon. It is not edible, but not chemically dangerous. Graphite can be made to be more dangerous than Pb depending on ingenuity. For instance if you powder graphite and force a person to breath the powder until they choke, it is more dangerous that a […]
What are signs of bad rotors?
What are signs of bad rotors? Symptoms of a Bad or Failing Brake Rotor/Disc Noisy brakes. One of the first symptoms commonly associated with bad brake rotors is noise. Vibrations from the brakes. Another symptom of bad brake rotors is excessive vibration coming from the brakes. Grooves or score marks on the rotor. How much […]
Is heart disease still the number one killer?
Is heart disease still the number one killer? While heart disease is often considered a man’s disease, it doesn’t discriminate. It’s the number one killer of both men and women in the United States. How do you lower all cause mortality? They found that, compared with taking 4,000 steps per day, a number considered to […]
How do rocks handle stress?
How do rocks handle stress? Rocks have three possible responses to increasing stress (illustrated in Figure below): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks. What causes rocks to […]
How many different types of batteries are there?
How many different types of batteries are there? three types What is the main function of a battery? A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The […]
How long must you boil water to make it safe to drink?
How long must you boil water to make it safe to drink? Boil water, if you do not have bottled water. Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water […]
Is buoyant force constant?
Why the adsorption is always exothermic?
Why the adsorption is always exothermic? The particles are attached to the surface of another medium for the reaction to take place. During this process the residual forces on the surface of adsorbent decreases which in turn decreases the surface energy. This energy appears in the form of heat, hence adsorption is exothermic in nature. […]
