Answer the following question given this paragraph: Competition between different species is called interspecific competition. It might lead to the less well-adapted species going extinct. Or it might lead to one or both species evolving specialized adaptations. For example, competing species might evolve adaptations that allow them to use different food sources. You can see an example in Figure below . Q: A potential cause of extinction, competition between different species is called what? Choices: - parasitism - intraspecific competition - mutualism - interspecific competition A:
interspecific competition

Answer the following question given this paragraph: Water power does not burn a fuel. So it causes less pollution than many other kinds of energy. Water power is also a renewable resource. Water keeps flowing downhill. Although we use some of the energy from this movement, we are not using up the water. Q: What type of resource is water power? Choices: - biological - nonrenewable - geothermal - renewable A:
(Answer)
renewable
Ques: Answer the following question given this paragraph: Algae play significant roles as producers in aquatic ecosystems. Microscopic forms live suspended in the water column. They are the main component of phytoplankton. As such, they contribute to the food base of most marine ecosystems. Q: What is the main component of phytoplankton? Choices: - amoebas - seawater - cells - algae A:
Ans: algae

Answer the following question given this paragraph: When you pour a glass of water, or fill a car with gasoline, you observe that water and gasoline flow freely. But when you pour syrup on pancakes or add oil to a car engine, you note that syrup and motor oil do not flow as readily. The viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 10.15, have higher viscosities. We can measure viscosity by measuring the rate at which a metal ball falls through a liquid (the ball falls more slowly through a more viscous liquid) or by measuring the rate at which a liquid flows through a narrow tube (more viscous liquids flow more slowly). Q: The viscosity of a liquid is a measure of what? Choices: - resistance to change form - ability to absorb flow - adaptability to surroundings - resistance to flow A:
(A).
resistance to flow
Ques:Answer the following question given this paragraph: Q: What is the only commercial way of reproducing plants such as orchids? Choices: - sexual reproduction - cross-breeding - grafting - cloning A:

Ans:cloning
Question: Answer the following question given this paragraph: Animal and Human Parasites and Pathogens Fungi can affect animals, including humans, in several ways. Fungi attack animals directly by colonizing and destroying tissues. Humans and other animals can be poisoned by eating toxic mushrooms or foods contaminated by fungi. In addition, individuals who display hypersensitivity to molds and spores develop strong and dangerous allergic reactions. Fungal infections are generally very difficult to treat because, unlike bacteria, fungi are eukaryotes. Antibiotics only target prokaryotic cells, whereas compounds that kill fungi also adversely affect the eukaryotic animal host. Many fungal infections ( mycoses) are superficial and termed cutaneous (meaning "skin") mycoses. They are usually visible on the skin of the animal. Fungi that cause the superficial mycoses of the epidermis, hair, and nails rarely spread to the underlying tissue (Figure 13.26). These fungi are often misnamed "dermatophytes" from the Greek dermis skin and phyte plant, but they are not plants. Dermatophytes are also called "ringworms" because of the red ring that they cause on skin (although the ring is caused by fungi, not a worm). These fungi secrete extracellular enzymes that break down keratin (a protein found in hair, skin, and nails), causing a number of conditions such as athlete's foot, jock itch, and other cutaneous fungal infections. These conditions are usually treated with over-the-counter topical creams and powders, and are easily cleared. More persistent, superficial mycoses may require prescription oral medications. Q: Antibiotics only target prokaryotic cells - they do not affect fungi, which are not prokaryotic, but instead what? Choices: - chloroplasts - mammals - plants - eukaryotic A:
Answer:
eukaryotic
