Jupiter is an outer planet. It is the largest planet in the solar system at about 1,000 times the size of Earth. The Sun is about 1,000 times bigger than Jupiter! ( Figure below ). Answer: the sun

Passage: One useful application of PET scanning is in the diagnosis of Alzheimer's disease. This debilitating condition associated with memory loss primarily occurs in elderly individuals. A protein known as beta-amyloid gradually forms deposits, or plaques, in the brain. Severe memory loss and impaired movement appear to be direct results of the plaque growth. Answer: elderly
Alzheimers disease is associated with memory loss in what group of people?

Passage: One of the two generations of a plant's life cycle is typically dominant to the other generation. Whether it's the sporophyte or gametophyte generation, individuals in the dominant generation live longer and grow larger. They are the green, photosynthetic structures that you would recognize as a fern, tree, or other plant (see Figure below ). Individuals in the nondominant generation, in contrast, may be very small and rarely seen. They may live in or on the dominant plant. Answer: dominant generation
Which generation of a plant is generally larger and longer-lived?
