Q: Answer the following question given this paragraph: Pollination by Bats In the tropics and deserts, bats are often the pollinators of nocturnal flowers such as agave, guava, and morning glory. The flowers are usually large and white or pale-colored; thus, they can be distinguished from the dark surroundings at night. The flowers have a strong, fruity, or musky fragrance and produce large amounts of nectar. They are naturally large and wide-mouthed to accommodate the head of the bat. As the bats seek the nectar, their faces and heads become covered with pollen, which is then transferred to the next flower. Q: What mammal is often a pollinator of nocturnal flowers? A:

OPTIONS:
- sunbirds
- hummingbirds
- rabbits
- bat

A: bat

input: OPTIONS:
- flagellum
- cell wall
- mitochondria
- cell nucleus Now, answer this question: Answer the following question given this paragraph: Eukaryotes evolved about 2 billion years ago. Unlike prokaryotes, eukaryotes have a cell nucleus. They have more structures and are better organized. Organelles within a eukaryote can perform certain functions. Some supply energy; some break down wastes. Eukaryotes were better able to live and so became the dominant life form. You can see an example of a eukaryotic cell below ( Figure below ). Q: Unlike prokaryotes, eukaryotes have a what? A:
A:
output: cell nucleus

Answer the following question given this paragraph: 24.2 Production of Electromagnetic Waves Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave. The strengths of the electric and magnetic parts of the wave are related by. Q: What are electromagnetic waves created by? A:

OPTIONS:
- Static Charges
- gravitational charges
- particle charges
- oscillating charges

Answer: oscillating charges

Problem: OPTIONS:
- baryons
- cores
- isotopes
- nucleons
Q: Answer the following question given this paragraph: Summary Subatomic particles of the nucleus (protons and neutrons) are called nucleons. Anuclide is an atom with a particular number of protons and neutrons. An unstable nucleus that decays spontaneously is radioactive, and its emissions are collectively called radioactivity. Isotopes that emit radiation are calledradioisotopes. Each nucleon is attracted to other nucleons by the strong nuclear force. Stable nuclei generally have even numbers of both protons and neutrons and a neutron-to-proton ratio of at least 1. Nuclei that contain magic numbers of protons and neutrons are often especially stable. Superheavy elements, with atomic numbers near 126, may even be stable enough to exist in nature. Q: What are subatomic particles of the nucleus called? A:
Answer: nucleons

Answer the following question given this paragraph: Types of Root Systems Root systems are mainly of two types (Figure 30.15). Dicots have a tap root system, while monocots have a fibrous root system. A tap root system has a main root that grows down vertically, and from which many smaller lateral roots arise. Dandelions are a good example; their tap roots usually break off when trying to pull these weeds, and they can regrow another shoot from the remaining root). A tap root system penetrates deep into the soil. In contrast, a fibrous root system is located closer to the soil surface, and forms a dense network of roots that also helps prevent soil erosion (lawn grasses are a good example, as are wheat, rice, and corn). Some plants have a combination of tap roots and fibrous roots. Plants that grow in dry areas often have deep root systems, whereas plants growing in areas with abundant water are likely to have shallower root systems. Q: Root systems are mainly of two types. dicots have a tap root system, while monocots have a what? A:

OPTIONS:
- long root system
- runner root system
- attaching root system
- fibrous root system

Answer:
fibrous root system
