Question: Q: Unlike plants, animal species rely almost exclusively on what type of reproduction? Read this paragraph and choose the correct option from the provided answers: Introduction Plants have evolved different reproductive strategies for the continuation of their species. Some plants reproduce sexually, and others asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction. Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents. Flowers are often the showiest or most strongly scented part of plants. With their bright colors, fragrances, and interesting shapes and sizes, flowers attract insects, birds, and animals to serve their pollination needs. Other plants pollinate via wind or water; still others self-pollinate. Choices: - pollination - multiplication - regeneration - sexual reproduction A:
Answer: sexual reproduction

Question: Q: What kind of energy comes from the position of a charged particle in an electric field? Read this paragraph and choose the correct option from the provided answers: Electric potential energy comes from the position of a charged particle in an electric field. For example, when two negative charges are close together, they have potential energy because they repel each other and have the potential to push apart. If the charges actually move apart, their potential energy decreases. Electric charges always move spontaneously from a position where they have higher potential energy to a position where they have lower potential energy. This is like water falling over a dam from an area of higher to lower potential energy due to gravity. Choices: - solar energy - mechanical energy - thermal energy - potential energy A:
Answer: potential energy

Question: Q: What is an alpha particle with two protons and two neutrons called? Read this paragraph and choose the correct option from the provided answers: In alpha decay, energy and an alpha particle are emitted by a nucleus that is unstable because it has too many protons. An alpha particle consists of two protons and two neutrons, so it is actually a helium nucleus. Choices: - chloride nucleus - hydrogen nucleus - hydrogen nucleus - helium nucleus A:
Answer:
helium nucleus
