Q: What is the method that is a plan for asking questions and testing possible answers called? Read this paragraph and choose the correct option from the provided answers: At the heart of science is the scientific investigation, which is done by following the scientific method. A scientific investigation is a plan for asking questions and testing possible answers. Choices: - forecasting - sample size - independent variable - scientific investigation A:
scientific investigation

Q: What causes fertilization to occur? Read this paragraph and choose the correct option from the provided answers: Many animals have a relatively simple life cycle. A general animal life cycle is shown in Figure below . Most animals spend the majority of their life as diploid organisms. Just about all animals reproduce sexually. Diploid adults undergo meiosis to produce sperm or eggs. Fertilization occurs when a sperm and an egg fuse. The zygote that forms develops into an embryo. The embryo eventually develops into an adult. Choices: - accumulation and an egg fuse - tissue and an egg fuse - genetic and an egg fuse - sperm and an egg fuse A:
sperm and an egg fuse

Q: Q: What type of force always opposes the direction of motion? Read this paragraph and choose the correct option from the provided answers: Kinetic friction acts between two surfaces that are in contact and in motion with respect to each other. This force reduces the acceleration and it always opposes the direction of motion. Choices: - binary friction - strong force - harmonic friction - kinetic friction A:
A: kinetic friction

Question: Q: What concentrates wave energy or disperses it? Read this paragraph and choose the correct option from the provided answers: Wave refraction either concentrates wave energy or disperses it. In quiet water areas, such as bays, wave energy is dispersed. This allows sand to be deposited. Land that sticks out into the water is eroded by the strong wave energy. The wave energy concentrates its power on the wave-cut cliff . Choices: - wave diffusion - a prism - wave reflection - wave refraction A:
Answer: wave refraction

Q: Which law explains why a ship weighing thousands of metric tons floats on water? Read this paragraph and choose the correct option from the provided answers: Do you see the man sitting on top of this tanker truck? He gives you a sense of how big the truck is. What's behind the truck? Is it a huge apartment complex? It's just as massive as a very large building, but it's not even resting on land. It's a giant cruise ship, and it's floating on water. The ship weighs about 100,000 metric tons. How can such a tremendous weight float on water? Why doesn't it sink to the bottom of the ocean instead? Archimedes' law explains why. Choices: - hofstadter ' law - ganymede ' law - water pressure law - archimedes' law A:
**Answer**
archimedes' law

Q: For what kind of animal is communication essential? Read this paragraph and choose the correct option from the provided answers: Communication is any way that animals share information. Many animals live in social groups. For these animals, being able to communicate is essential. Communicating increases the ability of group members to cooperate and avoid conflict. Communication may help animals work together to find food and defend themselves from predators. It also helps them find mates and care for their offspring. In addition, communication helps adult animals teach the next generation learned behaviors. Therefore, communication generally improves the chances of animals surviving and reproducing. Choices: - anti-social animals - new born animals - migrating animals - social animals A:
(A).
social animals
