Answer:
A. I would be startled by the sudden noise and would probably take cover some wheres. B. My nerves in my ears would send a signal to my brain causing my twitching muscle fibers to react quickly and heart might stop for a moment. C. The heart rate would increase the brain would be aware that there may be more sudden noises or events your adrenaline would be pumping and your quick twitch muscle fibers would probably be tense or contracted ready to make quick sudden movements if necessary and your hairs would stick up i guess as extra senses for if something would touch you.
Explanation:
not to mention but by the time you are startled your senses would probably be heightened due to you being aware of your surroundings such as you would be constantly looking around you would hear better and probably move quicker for a short period of time due to pumping adrenaline.

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.
The correct answer is Manganese (Mn).
<span>Manganese functions as a cofactor for a large variety of enzymes with many functions including those active in gluconeogenesis. <span>Pyruvate carboxylase that catalyzes breakdown of pyruvate to oxaloacetate requires manganese (or magnesium) for its function. Phosphoenolpyruvate carboxykinase also needs Mn.</span></span>
Answer:
mobile sources – such as cars, buses, planes, trucks, and trains.
stationary sources – such as power plants, oil refineries, industrial facilities, and factories.
area sources – such as agricultural areas, cities, and wood burning fireplaces.
