A: sunspots

Answer the following question given this paragraph: Two nuclei must collide for fusion to occur. High temperatures are required to give the nuclei enough kinetic energy to overcome the very strong repulsion resulting from their positive charges. A nuclear reactor consists of the following: 1. A nuclear fuel. A fissionable isotope must be present in large enough quantities to sustain a controlled chain reaction. The radioactive isotope is contained in tubes called fuel rods. A moderator. A moderator slows neutrons produced by nuclear reactions so that they can be absorbed by the fuel and cause additional nuclear reactions. A coolant. The coolant carries heat from the fission reaction to an external boiler and turbine where it is transformed into electricity. Q: What must two nuclei do for fusion to occur? A:
OPTIONS:
- explode
- melt
- repel each other
- collide
collide

Answer the following question given this paragraph: Layers of Human Skin. The outer layer of the skin is the epidermis, and the inner layer is the dermis. Most skin structures originate in the dermis. Q: Where do most skin structures originate in? A:
OPTIONS:
- epidermis
- cuticle
- hypodermis
- dermis

Answer: dermis

Question: Answer the following question given this paragraph: 47.2 | The Importance of Biodiversity to Human Life By the end of this section, you will be able to: Identify chemical diversity benefits to humans Identify biodiversity components that support human agriculture Describe ecosystem services It may not be clear why biologists are concerned about biodiversity loss. When biodiversity loss is thought of as the extinction of the passenger pigeon, the dodo bird, and even the woolly mammoth, the loss may appear to be an emotional one. But is the loss practically important for the welfare of the human species? From the perspective of evolution and ecology, the loss of a particular individual species is unimportant (however, the loss of a keystone species can lead to ecological disaster). Extinction is a normal part of macroevolution. But the accelerated extinction rate means the loss of tens of thousands of species within our lifetimes, and it is likely to have dramatic effects on human welfare through the collapse of ecosystems and in added costs to maintain food production, clean air and water, and human health. Agriculture began after early hunter-gatherer societies first settled in one place and heavily modified their immediate environment. This cultural transition has made it difficult for humans to recognize their dependence on undomesticated living things on the planet. Biologists recognize the human species is embedded in ecosystems and is dependent on them,. Q: The passenger pigeon, the dodo bird, and the woolly mammoth represent individual cases of what fate? A:
OPTIONS:
- isolation
- compression
- accumulation
- extinction
Answer: extinction

input with options: Answer the following question given this paragraph: For these plants, the name says it all. Vascular seedless plants have vascular tissue but do not have seeds. Remember that vascular tissue is specialized tissue that transports water and nutrients throughout the plant. The development of vascular tissue allowed these plants to grow much taller than nonvascular plants, forming ancient swamp forests. Most of these large vascular seedless plants are now extinct, but their smaller relatives still remain. Vascular tissue includes xylem, which transports water from the roots to the rest of the plant; and phloem, which transports sugars and nutrients from the leaves throughout the plant. Q: What is the specialized tissue that transports water and nutrients throughout the plant and allows these plants to grow taller? A:
OPTIONS:
- blood vessels
- dioxide tissue
- fiber tissue
- vascular tissue
output: vascular tissue

Problem: OPTIONS:
- hibernation
- ruination
- condensation
- pollination
Q: Answer the following question given this paragraph: Pollination by Insects Bees are perhaps the most important pollinator of many garden plants and most commercial fruit trees (Figure 32.12). The most common species of bees are bumblebees and honeybees. Since bees cannot see the color red, bee-pollinated flowers usually have shades of blue, yellow, or other colors. Bees collect energy-rich pollen or nectar for their survival and energy. Q: What important function do bees perform on garden plants and many commercial fruit trees? A:
Answer:
pollination
