Q: According to one of einstein's theory, while light consists of particles, it behaves like this. Read this paragraph and choose the correct option from the provided answers: After Einstein proposed his theory, evidence was discovered to support it. For example, scientists shone laser light through two slits in a barrier made of a material that blocked light. You can see the setup of this type of experiment in the Figure below . Using a special camera that was very sensitive to light, they took photos of the light that passed through the slits. The photos revealed tiny pinpoints of light passing through the double slits. This seemed to show that light consists of particles. However, if the camera was exposed to the light for a long time, the pinpoints accumulated in bands that resembled interfering waves. Therefore, the experiment showed that light seems to consist of particles that act like waves. Choices: - thermodynamics - tides - molecules - waves A:
waves

Q: Prokaryotes divide via binary fission and do not undergo what process of cell division? Read this paragraph and choose the correct option from the provided answers: Reproduction Reproduction in prokaryotes is asexual and usually takes place by binary fission. Recall that the DNA of a prokaryote exists as a single, circular chromosome. Prokaryotes do not undergo mitosis. Rather the chromosome is replicated and the two resulting copies separate from one another, due to the growth of the cell. The prokaryote, now enlarged, is pinched inward at its equator and the two resulting cells, which are clones, separate. Binary fission does not provide an opportunity for genetic recombination or genetic diversity, but prokaryotes can share genes by three other mechanisms. Choices: - prophase - meiosis - fusion - mitosis A:
(Answer)
mitosis

Ques: Q: The urinary system can be considered a smaller part of what other body system? Read this paragraph and choose the correct option from the provided answers: Sometimes, the urinary system ( Figure below ) is called the excretory system. But the urinary system is only one part of the excretory system. Recall that the excretory system is also made up of the skin, lungs, and large intestine, as well as the kidneys. The urinary system is the organ system that makes, stores, and gets rid of urine. Choices: - circulatory - extraneous - sensory - excretory A:
Ans: excretory

Q: Colonial organisms were probably one of the first evolutionary steps towards which type of organisms? Read this paragraph and choose the correct option from the provided answers: Colonial organisms were probably one of the first evolutionary steps towards multicellular organisms. Algae of the genus Volvox are an example of the bridge between colonial organisms and multicellular organisms. Each Volvox , shown in Figure above , is a colonial organism. It is made of up to 50,000 photosynthetic flagellate algae that are grouped together into a hollow sphere. Volvox live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700. Choices: - double cellular - mutated - fetus - multicellular A:
(A).
multicellular

Ques:Q: What type of winds occur when air is forced over a mountain range? Read this paragraph and choose the correct option from the provided answers: Chinook winds ( Figure below ) occur when air is forced over a mountain range. Warm air rises over the Sierra Nevada in California, for example, because it is pushed eastward by the westerly winds. The air cools as it rises and precipitates. The air is now dry. It sinks down the far side of the mountains and may create strong winds. These Chinook winds are relatively warm. If there is snow, the winds may melt it quickly. The dry sinking air creates a rainshadow effect . Rainshadow effect is responsible for many of the world's deserts. Choices: - local winds - trade winds - doldrums - chinook winds A:

Ans:chinook winds

Q: Which body part helps roundworm prevent their body from expanding? Read this paragraph and choose the correct option from the provided answers: Roundworms have a tough covering of cuticle on the surface of their body. It prevents their body from expanding. This allows the buildup of fluid pressure in their partial body cavity. The fluid pressure adds stiffness to the body. This provides a counterforce for the contraction of muscles, allowing roundworms to move easily over surfaces. Choices: - scales - plate - skin - tough cuticle covering A:
tough cuticle covering
