The correct answer is sewage, I just did this stuff in class last week.
Answer: Simple Diffusion Across the Cell (Plasma) Membrane
Explanation:
pretty much the structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
HOPE THIS HELPS!!
Answer: C
A. Intentional variation
B. Lab cloning
C. Transgenic DNA
D. Selective breeding
Explanation:
Genetic modification changes an organisms genes through biotechnology; the genes in the form of DNA are swapped within and between related groups called species. One of the first genetically modified tomatoes dubbed the Flavr Savr, was made for longer shelf lives. A gene was added from a different species, to slow down the ripening of the tomato, without affecting its flavor or nutritious content along with reducing its susceptibility being infected with a fungus. The altered tomato contained transgenic DNA and can be classified as a transgenic organism.
