Answer:
The Oxygen liberated in photosynthesis comes from photolysis of water.
The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.
Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.
However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+ from photolysis of water to form radioactive labeled carbohydrate(CHO)

Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat. Also, I hope all of this work gives me brainliest :/
Answer:
Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.
Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.
The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.
