False, most of the nutrients are absorbed in our stomach. The intestines are mainly for waste.
If one strand of DNA contains the sequence TACGGATCACTAATC, the other strand will contain the sequence ATGCCTAGTGATTAG.
Answer:
C
Explanation:
Semiconservative replication means that strand will also be used. (Pretty sure)
The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
