Does personality change with age? Personality may change somewhat over time, but not greatly. These changes do not seem to be systematically related to thinking skills or other common changes we experience in ageing. This suggests that we can retain our individuality as we age. Don’t worry about your personality. Are the Big Five personality […]
How does pollution affect marine life?
How does pollution affect marine life? It is estimated that up to 13 million metric tons of plastic ends up in the ocean each year—the equivalent of a rubbish or garbage truck load’s worth every minute. Fish, seabirds, sea turtles, and marine mammals can become entangled in or ingest plastic debris, causing suffocation, starvation, and […]
What do viruses inject into cells?
What do viruses inject into cells? During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell’s genetic material and induces it to replicate the viral genome. How do viruses attach […]
What is the change in electric potential energy?
What is the change in electric potential energy? The electron will accelerate toward a higher electric potential due to its negative charge. The change in potential energy is the charge times the potential difference (equation 20-2). The change in potential energy equals the gain in kinetic energy, which can then be used to find the […]
Do all uncontrolled compartment fires develop into a flashover?
Do all uncontrolled compartment fires develop into a flashover? Flashover will not always occur. Two interrelated factors have a major influence on fire development within a compartment. First, the fuel must have sufficient heat energy to develop flashover conditions. What factor helps determine the flow path in a structure fire? The direction and velocity of […]
What type of lens do you have in your eye?
What is standard reduction potentials?
What is standard reduction potentials? The standard reduction potential is the reduction potential of a molecule under specific, standard conditions. Standard reduction potentials can be useful in determining the directionality of a reaction. The reduction potential of a given species can be considered to be the negative of the oxidation potential. How do you calculate […]
What is the site and product of fertilization in a flower?
What is the site and product of fertilization in a flower? The site of fertilization in a flowering plant is ovary and product is fruit. What is cross pollination and self pollination 10? 1) The process of transferring the pollen grains from the anther to the stigma of the same flower or the stigma of […]
What are the functions of viscometer?
What are the functions of viscometer? A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. How do you test for viscosity? Ways to Measure Viscosity Capillary Viscometer. The earliest methods for measuring […]
