Answer:
False
Explanation:
A double-helical DNA molecule consists of two DNA strands. A DNA strand has free 5' phosphate at one end and a free hydroxyl group (OH) at its 3' end. A DNA double helix is said to be antiparallel since each end of the double helix has an exposed 5' phosphate on one strand and a free 3' hydroxyl group (OH) on the other. This means that the two DNA strands run in opposite directions. A phosphate group is always esterified to the 5' carbon of the pentose sugar; never at its 3' end.
The correct answer is: Artificial selection (selective breeding).
Artificial Selection is a form of selection, totally influenced by human, in which traits that should be passed onto offspring are chosen by human. Selective breeding was used long before the genetics was discoverd. Farmers used individuals with beneficial traits, larger in size, with bigger fruit etc.
Hunting is also one type of selective breeding, since the hunters choose the animal and remove it from the population (gene pool), leaving the “weaker” to pass on to the next generation.

conduct research on the types of organisms that live in the ecosystem you choose -
Ecosystems, or biological communities, comprise both living organisms such as animals, plants, insects, and microorganisms and nonliving components such as rocks, soil, water, and sunshine.
- Producers are plants and algae that manufacture their own sustenance.
- Herbivores eat plants and are classified as main consumers.
- Secondary consumers are carnivores that devour herbivores at the third level.
- Tertiary consumers are predators that consume other carnivores.
