False. Strontium 90 has a half life of only 30 years, and as millions of years pass, about the time fossils have been around, most if not all of any strontium would have decayed.
<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
<span>The answer is reflection. Objects that do not produce their own light, reflect light when the light is shone on them. This is because the light bounces off them by reflection. One example is the reflection of sunlight by the moon so it is visible in the night. </span>
<h2>Transparency of an Increment </h2>
An increment is all the uncompleted things which are completed during dash and also their values. So the sprint enhances the transparency of an increment. It indicates that the items which remained uncompleted are completed by running very fast. In this way, the transparency of an increment increases.
