Answer:
genetically unique
Explanation:
each of which has half the number of chromosomes as the parent cell.
Answer:
due to gmos we can expand the shelf life of many of our foods and prevent them from the harm of pests. You night be rhinking why not use pesticides? well, we did but eventually the pests became immune to the low dose of pesticide. over time we gradually increased our uses of pesticides. more commonly round up. this pesticide specifically was known for being a carcinogen. (something that causes cancer.) Genetically modifying a crop can severely decrease the amount of pesticides used for our crops and could also potentially drop the prices. for example, in hawaii during the 1940s to 1990s the ringspot viruses hit the hawaiian papaya harvest hard. this reduced the amount of papaya produced by 50 percent by 1993 and 2006. the ringspot virus nearly wiped out the entire crop. within 11 months, the hawaiian papya was saved. due to gmos of course. this is because scientists took genes from immune papayas which very rarelt occured (at the time) and injected it into many other papya plants. as the plants grew, new papaya was produced which was immine to ringspit virus. PAPAYA WAS SAVED!!!!

Individuals adapt to their environments and, thereby, evolve
Explanation:
Natural selection is the main process which advances evolution by aiding organisms to survive and produce more offspring through adapting more to their environment. Mutations, gene transfer, and genetic variations also drive evolution.
Both natural selection and evolution work on genetic behaviors in populations rather than individuals. Both natural selection and evolution are involved in generating changes over generations. Examples of evolution is the disappearing of tail bone, decreased head size and for natural selection example is the long and short necked giraffe.
Answer:
intersecting circle and the universal affarmative
Explanation:
Answer:
850 meters
Explanation:
From the base of the epipelagic zone to a depth of about 850 meters, there is still enough light for a human to see. The second zone between 200 meters and 1,000 meters is known as the "twilight zone". Some light penetrates as far as 1000 meters down into the ocean.
