Answer:

C. could not provide a mechanism for moving continents

Explanation:

Without the discovery of magnetic reversals recorded on the ocean floor, scientists  could not provide a mechanism for moving continents.

Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents  and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.

Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.

Nimfa-mama [501]

Answer:

100%

Explanation:

No matter how many factors are in the cross, if an 2 purebred (homozygous individuals) are crossed, (one dominant, one recessive) the dominant phenotype will always be displayed.

Imagine a cross with between two individuals true breeding for 6 traits. One shows all dominant genotypes, one shows all recessive genotypes. The only gametes those individuals can pass on will always produce heterozygotes.

AABBCCDDEEFFGG x aabbccddeeffgg

The first individual can only give ABCDEFG alleles. The second individual can only give abcdefg alleles. Therefore, all offspring will be AaBbCcDdEeFfGg, and will therefore express the dominant trait.
