Q: What effect causes winds and currents to form circular patterns? Read this paragraph and choose the correct option from the provided answers: The Coriolis effect causes winds and currents to form circular patterns. The direction that they spin depends on the hemisphere that they are in. Choices: - horse latitudes - jet stream - centrifugal effect - coriolis effect A:
coriolis effect

Q: What are the lines of force in the electric field around a charged particle called? Read this paragraph and choose the correct option from the provided answers: Field lines represent lines of force in the electric field around a charged particle. The lines bend when two particles interact. What would the lines of force look like around two negatively charged particles?. Choices: - terrain lines - voltage lines - ionic zone - field lines A:
field lines

Q: Q: Carbon fixation is the first step of what cycle involving light reactions? Read this paragraph and choose the correct option from the provided answers: As Melvin Calvin discovered, carbon fixation is the first step of a cycle. Like an electron transport chain, the Calvin Cycle, shown in Figure below , transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transfer chain, excited electrons lose energy to NADPH and ATP. In the Calvin Cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose. Choices: - sun cycle - life cycle - water cycle - calvin cycle A:
A: calvin cycle

Question: Q: What kind of current flows in just one direction? Read this paragraph and choose the correct option from the provided answers: When current flows in just one direction, it is called direct current (DC) . The diagram below shows how direct current flows through a simple circuit. An example of direct current is the current that flows through a battery-powered flashlight. In addition to batteries, solar cells and fuel cells can also provide direct current. Choices: - physical current - slow current - Alternating current - direct current A:
Answer: direct current

Q: What is the series of changes in the reproductive system of a mature female that happens monthly? Read this paragraph and choose the correct option from the provided answers: The menstrual cycle is a series of changes in the reproductive system of mature females that repeats every month. While the egg and follicle are developing in the ovary, tissues are building up inside the uterus , the reproductive organ where the baby would develop. The uterus develops a thick lining covered in tiny blood vessels. This prepares the uterus to receive an egg that could develop into a child (a fertilized egg). The occurs during the first part of the cycle. Choices: - urinary cycle - fetal cycle - pregnancy - menstrual cycle A:
**Answer**
menstrual cycle

Q: Q: Under appropriate conditions, the attractions between all molecules in what state will cause them to form liquids or solids? Read this paragraph and choose the correct option from the provided answers: Forces between Molecules Under appropriate conditions, the attractions between all gas molecules will cause them to form liquids or solids. This is due to intermolecular forces, not intramolecular forces. Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 10.5 illustrates these different molecular forces. The strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule. For example, to overcome the IMFs in one mole of liquid HCl and convert it into gaseous HCl requires only about 17 kilojoules. However, to break the covalent bonds between the hydrogen and chlorine atoms in one mole of HCl requires about 25 times more energy430 kilojoules. Choices: - soild - plasma - liquid - gas A:
A: gas
