Question

The table below compares the scientific hypotheses proposed by Gregor Mendel and Alfred Wegener.

 Gregor Mendel (1822–1884)Alfred Wegener (1880–1930)

ObservationThe flower color of a pea plant depends on the flower color of the parent plants.Noticed that the continents seemed to fit together like a jigsaw puzzle and that fossilized plants were similar on different continents. HypothesisFor each trait, an organism inherits one gene from each parent which controls that trait.The continents once formed a single giant continent. They drifted away from each other to form today's continents. IssueMissing knowledge of the molecule that contains genes.Missing the mechanism that gives rise to continental drift. Evidence The genetic molecule DNA was first understood by Watson and Crick in 1953.    After the 1950s, developments in geology showed that the seafloor was spreading due to magma currents under the earth's crust.
 
Both Gregor Mendel and Alfred Wegener proposed ideas that were not accepted completely by the scientific community during their lifetimes. What did their ideas have in common?

1. They were presented by amateur scientists who were not accepted by the scientific community.

2. They explained aspects of genetics that required Watson and Crick's data to be understandable.

3. They needed mathematics to prove their data, and that field was not developed at the time.

4. They required supporting evidence which could not be provided with the existing technology.

Answer 1

They required supporting evidence which could not be provided with the existing technology.

Step-by-step explanation:

I took the quiz already and it was correct.

Answer 2

Both Gregor Mendel and Alfred Wegener proposed ideas that were not accepted completely by the scientific community during their lifetimes but They required supporting evidence which could not be provided with the existing technology.
