C two identical daughter cells.
Answer:
C
Explanation:
No, because some organisms are not diploid and have more than two sets of chromosomes.
Diatoms are made of silica (hydrated silicon dioxide)
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.
Gravity is one reason but also it depends in the speed, if the wave is fast, it will go higher and then bend. hope i helped :D
