Answer:
Meteorologist are professionals who study the weather and climatic conditions of an environment. They usually have large amounts of data from previous years.
Their predictions are usually according to these past data on sea surface temperatures and upper air measurements.
Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
Answer:
mutations cause most cases of cancer. Some acquired mutations can be caused by things that we are exposed to in our environment, including cigarette smoke, radiation, hormones, and diet. Other mutations have no clear cause, and seem to occur randomly as the cells divide.
Answer:
A
Explanation:
The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.
Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
