1/2 of a radioactive substance will remain after 3 half lives.
Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.
<h3>What does natural selection mean?</h3>
According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.
Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.
In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.

Taenia saginata/Taenia solium are commonly known as tapeworms is a <u>true</u> statement.
Explanation:
Tapeworms are long segmented parasitic flatworms which reside in the intestines of the host’s body. They belong to the phylum Platyhelminthes and scientifically called the Cestoda.
Tapeworm belonging to the Taenia species like the T. saginta, T. solium, T. asiatica etc causes parasitic infections called Taeniasis in the human body and affects the intestines.
Taenia saginata is the tapeworm which resides in pork and Taenia soleum resides in beef.
Humans can be infected with tapeworms when raw or improperly cooked pork or beef is consumed
