Plate tectonics this is the answer
Science proceeds by scientific method and use of experimental method. The answer is true because following these steps will get the steps and results you need. There is nothing more to be done. The method is observe a question, make a hypothesis, test the hypothesis with controlled experiment, analyze data. reject or accept hypothesis, and form a conclusion.
The answer is recessive alleles. Generally, a recessive allele
is the form of a gene that codes for a non-functional protein. When an individual inherits
recessive allele for a gene from both parents, then they are more likely to
suffer a disorder that is attributed to lack of the respective functional protein. Often the heterozygous individual will
not bear the disorder even though they carry
the recessive allele. This is because the
dominant allele is able to mask the
recessive allele by producing a functional
protein.
