Answer:
If the sequence of one strand on DNA is CTA GCT CCA, the
complementary strand is GAT CGA GGT.
Explanation:
The DNA molecule has four nitrogenous bases in its structure, two purines —adenine and guanine— and two pyrimidines, cytosine and thymine.
The two DNA strands are linked by hydrogen bonds established between their complementary nitrogenous bases, where a purine is complemented by a pyrimidine.
In the case of DNA, adenine is complemented by thymine and cytosine is complemented by guanine:
<em>A=T</em>
<em>C≡G</em>
In the sequence belonging to a DNA strand CTA GCT CCA, the strand that is complementary would be GAT CGA GGT.

Answer:
1-Wegener was a German meteorologist, geophysicist and polar researcher. In 1915 he published 'The Origin of Continents and Oceans', which outlined his theory of Continental Drift. Wegener was a member of four expeditions to Greenland.
2-The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
3-The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. ... The long-term result of plate tectonics is the movement of entire continents over millions of years
