In North Carolina and other soybean-producing states, many farmers grow a species of soybean known as Roundup Ready. Roundup is a weed-killing chemical that was produced by Monsanto, (recently purchased by Bayer). The farmer can directly spray Round-up on his fields and it will kill all the weeds, yet leave the soybean plants unharmed. One particular farmer noticed that after a few years of using Roundup weed killer, it became less effective, leaving more and ynore weeds alive after spraying. Which of the following explanations, best describes why these weeds remained alive? O After years of exposure to Roundup, the soybeans became more resistant to the weed killer. O Roundup-resistant weeds were more likely to survive and reproduce than were non-resistant individuals. O When Bayer bought out Monsanto, they started selling poor-quality Roundup. O Roundup-resistant weeds have less-efficient photosynthetic pathways than the original form.

You have been chosen as the lead student gardener for the CSUMB Future Farmers of America Club (FFAC). Your club is looking to you and your Bio211 plant experience to guide them. You arrive at the new FFAC garden plots where your club mates show you their cherry tree that they've been having trouble with. Originally, its leave would change color and fall off the tree, as expected, in the autumn. However, more recently the leaves started changing color and falling off in the spring time. Which hormone does the tree likely have in excess and why?

Danish is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover great numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty. Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds.
As scientists have developed more productive crop varieties, farmers have switched from growing many traditional varieties to new high-yield varieties. For example, in India, the 10,000 varieties of rice once grown have been reduced to 10 major ones for most of the rice crop. Why is this practice of reducing the varieties of a crop dangerous? Question options: It makes the overall crop more susceptible to pests and/or disease. It reduces the variety of crops available for human diets. it requires a larger investment than small farmers can make it could reduce or cause the extinction of some predatory insects
