In the context, An experimenter studies the heredity and the intelligence of the MZ twins who are reared together and for those who are reared apart. The findings of the experiment made by the researcher is a result of a cross sectional research method in this case.
Answer: Karl Von Baer was an Estonian biologist and generalized the observations around embryology into laws bearing its name.
His laws indicate that the earlier we are in the embryonic phase, the closer the classes of distant organisms look to each other. As embryos develop, they diverge further from embryos of other species.
The von Baer sequence poses more problems for evolutionary mythology since natural selection cannot explain the pattern of embryonic development. Natural selection does not want to know if a trait is widespread or specific. It does not see attributes so it cannot sort them according to a special sequence.
The answer should be C but please tell me what the last answe was.
Rust is caused when there is a redox reaction of iron and oxygen in the existence of water or air moisture. For the metal to be weakened by rust, the oxygen atoms needs to be mixed with metallic atoms to form the oxygen compound.
