Answer:
Wegener thought all the continents were once joined together in an "Urkontinent" before breaking up and drifting to their current positions. But geologists soundly denounced Wegener's theory of continental drift after he published the details in a 1915 book called "The Origin of Continents and Oceans." Part of the opposition was because Wegener didn't have a good model to explain how the continents moved apart.
Explanation:
The method that uses bacteria to copy DNA is : Recombinant DNA Technology.
To copy the DNA, recombinant DNA method use bacteria such as E. Coli whose plasmids has been combined with various gene to produce the substance that is wanted.
hope this helps
Because back then before pangaea occured the oceans we see today where all one before now they are seperated hope this helps.
If there was no nuclear membrane then the contest of the cell would spill out. and there will be nothing keeping everything together.
Rainfall is measured as depth on the surface of the Earth, typically in mm. We know the volume of water in the rain gauge: 1414 cubic centimetres. We know need to know the area of the Earth that this volume fell on. This would be the area of the funnel opening that points up to the sky to catch the rain. We know the diameter is 24 cm. So we need to determine the area of a circle with a diameter of 24 cm. The equation to use is: area = pi * radius^2. Since the radius of a circle is half the diameter, the equation is:
So area is 3.14159 * 12^2
= 452.39 cm^2Volume = depth * areadepth = volume/areadepth = 1414/452.39= 3.13 cm = 31.3 mm
