Answer the following question given this paragraph: Remember that individuals do not evolve. Their genes do not change over time. The unit of evolution is the population. A population consists of organisms of the same species that live in the same area. In terms of evolution, the population is assumed to be a relatively closed group. This means that most mating takes place within the population. The science that focuses on evolution within populations is population genetics . It is a combination of evolutionary theory and Mendelian genetics. Q: What is the unit of evolution? Choices: - species - community - biome - population A:
population
Answer the following question given this paragraph: Figure below shows a diagram of a simple doorbell. Like most doorbells, it has a button located by the front door. Pressing the button causes two electric contacts to come together and complete an electric circuit. In other words, the button is a switch. The circuit is also connected to a voltage source, an electromagnet, and the clapper of a bell. When current flows through the circuit, the electromagnet turns on, and its magnetic field attracts the clapper. This causes the clapper to hit the bell, making it ring. Because the clapper is part of the circuit, when it moves to strike the bell, it breaks the circuit. Without current flowing through the circuit, the electromagnet turns off. The clapper returns to its original position, which closes the circuit again and turns the electromagnet back on. The electromagnet again attracts the clapper, which hits the bell once more. This sequence of events keeps repeating as long as the button by the front door is being pressed. Q: When two electric contacts come together it completes a what? Choices: - charge - breaker - atom - cricuit A:
cricuit
Q: Answer the following question given this paragraph: There are several dietary sources of carbohydrates. Starch is found in many vegetables (especially potatoes) and baked goods. Sucrose (table sugar) is included as part of many prepared foods. Lactose is found in milk products, and maltose is present in some vegetables. Q: What is the chemical name of table sugar? Choices: - potassium - codeine - cellulose - sucrose A:
A: sucrose
Question: Answer the following question given this paragraph: Weeks 1624 Once the respiratory bronchioles form, further development includes extensive vascularization, or the development of the blood vessels, as well as the formation of alveolar ducts and alveolar precursors. At about week 19, the respiratory bronchioles have formed. In addition, cells lining the respiratory structures begin to differentiate to form type I and type II pneumocytes. Once type II cells have differentiated, they begin to secrete small amounts of pulmonary surfactant. Around week 20, fetal breathing movements may begin. Q: Alveolar ducts and broncioles are developing parts of what organ system? Choices: - nervous - immune - digestive - respiratory A:
Answer: respiratory

Answer the following question given this paragraph: Without Coriolis Effect the global winds would blow north to south or south to north. But Coriolis makes them blow northeast to southwest or the reverse in the Northern Hemisphere. The winds blow northwest to southeast or the reverse in the southern hemisphere. Q: What phenomenon makes global winds blow northeast to southwest or the reverse in the northern hemisphere and northwest to southeast or the reverse in the southern hemisphere? Choices: - muon effect - centrifugal effect - tropical effect - coriolis effect A:
**Answer**
coriolis effect
