Problem: OPTIONS:
- magnetism
- electrolysis
- electromagnetism
- radioactivity
Q: Answer the following question given this paragraph: Radioactivity is the ability of an atom to emit, or give off, charged particles and energy from the nucleus. The charged particles and energy are called by the general term radiation . Only unstable nuclei emit radiation. When they do, they gain or lose protons. Then the atoms become different elements. (Be careful not to confuse this radiation with electromagnetic radiation, which has to do with the light given off by atoms as they absorb and then emit energy. ). Q: What is the ability of an atom to emit, or give off, charged particles and energy from the nucleus? A:
Answer: radioactivity

Problem:OPTIONS:
- interconnection
- abjection
- natural selection
- coevolution

Answer the following question given this paragraph: Animals and Plants: Herbivory Coevolution of flowering plants and insects is a hypothesis that has received much attention and support, especially because both angiosperms and insects diversified at about the same time in the middle Mesozoic. Many authors have attributed the diversity of plants and insects to pollination and herbivory, or consumption of plants by insects and other animals. This is believed to have been as much a driving force as pollination. Coevolution of herbivores and plant defenses is observed in nature. Unlike animals, most plants cannot outrun predators or use mimicry to hide from hungry animals. A sort of arms race exists between plants and herbivores. To "combat" herbivores, some plant seedssuch as acorn and unripened persimmonare high in alkaloids and therefore unsavory to some animals. Other plants are protected by bark, although some animals developed specialized mouth pieces to tear and chew vegetal material. Spines and thorns (Figure 26.18) deter most animals, except for mammals with thick fur, and some birds have specialized beaks to get past such defenses. Q: What hypothetical link between development of herbivores and plant defenses is observed in nature, for instance in seeds that are unsavory to animals? A:
****
A: coevolution

Answer the following question given this paragraph: The heart is a muscular organ in the chest that consists mainly of cardiac muscle. It pumps blood through blood vessels by repeated, rhythmic contractions. Blood flows through four chambers of the heart when it beats. Heartbeat is controlled by electrical signals from special cells within the heart called the pacemaker. Q: What type of muscle makes up most of the heart? A:
OPTIONS:
- chest muscles
- heart muscle
- respiratory muscle
- cardiac muscle
cardiac muscle

Answer the following question given this paragraph: The epidermis of the leaf consists of a single layer of tightly-packed dermal cells. They secrete waxy cuticle to prevent evaporation of water from the leaf. The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen. Stomata are flanked by guard cells that swell or shrink by taking in or losing water through osmosis . When they do, they open or close the stomata (see Figure below ). Q: What type of cells make up the epidermis of a leaf? A:
OPTIONS:
- chloroplasts
- endothermic cells
- mesophyll
- dermal cells

Answer: dermal cells

Question: Answer the following question given this paragraph: Surface mining is used to obtain mineral ores that are near the surface. Blasting breaks up the soil and rocks that contain the ore. Enormous trucks haul the broken rocks to locations where the ores can be removed. Surface mining includes open-pit mining, quarrying, and strip mining. Q: What type pf mining is used to obtain mineral ores that are near the surface? A:
OPTIONS:
- multi-layered mining
- function mining
- core mining
- surface mining
Answer: surface mining
