Which of the following best describes how the periodic table is organized?
Which of the following best describes how the periodic table is organized? The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are […]
Does heat expand and cold contract?
Does heat expand and cold contract? Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms. Does Heat contract or expand? When a material is heated, the […]
Which principle is used in interference?
Which principle is used in interference? Interfering waves obey the principle of superposition. This means that the displacements of the two or more interfering waves can be added algebraically to produce the resultant wave. What is the effect on interference? Interference, in physics, the net effect of the combination of two or more wave […]
What is the final step of DNA replication?
What is the final step of DNA replication? 5) The last step of DNA Replication is the Termination. This process happens when the DNA Polymerase reaches to an end of the strands. What is Primase in DNA replication? Primase is an enzyme that synthesizes short RNA sequences called primers. Primase functions by synthesizing short RNA […]
What problems can you have with your trachea?
What problems can you have with your trachea? Causes Damage to the trachea or esophagus caused by surgery or other medical procedures. Damage caused by a long-term breathing tube or tracheostomy. Chronic infections (such as bronchitis) Emphysema. Gastroesophageal reflux disease (GERD) Inhaling irritants. Polychondritis (inflammation of cartilage in the trachea) Is your trachea on left […]
What is the 10% rule in stats?
What is the 10% rule in stats? The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a […]
What are polymers and its types?
What are polymers and its types? Types of Polymers Addition Polymers Poly(tetrafluoroethylene) Poly(vinyl Chloride) and Poly(vinylidene Chloride) Condensation Polymers Is wood a natural polymer? Wood contains natural polymers such as lignin, cellulose, and various hemi- celluloses but has very different properties from the synthetic polymers with which it is most often combined. What happens if […]
What are 3 ways waves can pass through an object?
What are 3 ways waves can pass through an object? Summary. Three ways that waves may interact with matter are reflection, refraction, and diffraction. Why do objects have color? Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected […]
