Answer:
Answer : Scientific theories are rigorously supported by numerous studies, and are hypotheses that, even up till date, have never been disproved.
Explanation:
Scientific theory can be explained as a theory that was highly supported by facts. This means that , it is continuously or repeatedly confirmed by observation and experiment by scientists.
Evolution can be described as changes that occur in the heritable characters over a period of time. This usually occurs through natural selection.
In this case, evolution is known to be a scientific theory, because it involved careful observations and confirming experiments by scientists.
Speciation! Speciation occurs when a single species becomes two or more separate populations by a geographical barrier. This changes each population’s environment which forces them to adapt. Eventually these populations will become so different from each other that they will not be able to interbreed populations and create fertile offspring. This is what makes them different species, but they still share a common ancestor.
A carrier is an individual which has a heterozygous genotype.
