In this field of sunflowers, variation exists. Some flowers are tall, others short, and finally some plants are an intermediate height. The tallest plants shade the shorter; the taller plants are pollinated first. Over time, we might expect this field of sunflowers to be mostly tall. According to this scenario, we would classify the production of the sunflowers in what area of this Venn diagram?
A) A.
Reactivate
B) B.

- 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.arrow_forwardMeristem culture helps in developing which of the following? a) Hybrid plants b) Virus free plants c) Tall plants d) Disease resistant plantsarrow_forwardWhich of the following problems has/have been addressed through the development ofgenetically modified plants? 1.
