Why do most mutations occur during DNA replication? A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can also occur as the result of exposure to environmental factors such […]

How do doctors and researchers decide whether a disease is a good candidate for gene therapy quizlet? How do doctors and researchers decide whether a disease is a good candidate for gene therapy? They ask a couple of questions such as is the disease caused by gene mutation, Easier to cure the less genes that […]

Does adding salt raise pH? Since adding salt to water does not result in any chemical reactions, the salt will not alter the pH level of water. What is the alkalinity of seawater? Estuarine pH levels generally average from 7.0 to 7.5 in the fresher sections, to between 8.0 and 8.6 in the more saline […]

What are fossil fuels used for today? Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity, or refine them for use as fuel for heating or transportation. Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels. How did all the […]

What converts nitrogen into a form plants can use? Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized […]

Which use of pesticides is most dangerous for humans? Insecticides cause the greatest number of pesticide poisonings in the United States. The most serious pesticide poisonings usually result from acute exposure to organophosphate and carbamate insecticides. Are food pesticides harmful to humans? Pesticides are chemicals used in agriculture to protect crops against insects, fungi, weeds […]

What happens to pressure when velocity increases? If pressure increases, the velocity decreases to keep the algebraic sum of potential energy, kinetic energy, and pressure constant. Similarly, if velocity increases, the pressure decreases to keep the sum of potential energy, kinetic energy, and pressure constant. Why does fluid pressure decrease when velocity increases? When air […]
