Answer the following question given this paragraph: Vegetative reproduction is a type of asexual reproduction found in plants. This type of reproduction occurs when new individuals are formed without the production of seeds or spores. The formation of new plants out of rhizomes or stolons is an example of vegetative reproductive, such as in the strawberry plant. Other plants use this type of reproduction to reproduce through bulbs or tubers, or shoots and suckers that form along lateral roots. See the Plant Biology concepts for additional information. Q: What kind of reproduction is vegetative reproduction? Choices: - sexual - meiosis - mitosis - asexual A:
asexual
Answer the following question given this paragraph: Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms. Hydrocarbons with double bonds are called alkenes. Those with triple bonds are called alkynes. Aromatic hydrocarbons consist of six carbon atoms in a ring shape, connected by alternating single and double bonds. Q: What are hydrocarbons with double bonds called? Choices: - aldehydes - alcohols - amines - alkenes A:
alkenes
Q: Answer the following question given this paragraph: Birds are endothermic tetrapod vertebrates. They are bipedal and have wings and feathers. Their organ systems are adapted for flight. For example, they have light-weight air-filled bones and a large four-chambered heart. Birds also have relatively large brains and a high level of intelligence. Q: In birds, lightweight air-filled bones and a large four-chambered heart are examples of adaptations for what purpose? Choices: - speed - long lifespan - mating - flight A:
A: flight
Question: Answer the following question given this paragraph: Biodiversity generally increases the productivity and stability of ecosystems. It helps ensure that at least some species will survive environmental change. It also provides many other ecosystem services. For example:. Q: What helps ensure that, at least, some species will survive environmental change? Choices: - reproduction - ecosystem - spontaneous mutation - biodiversity A:
Answer: biodiversity

Answer the following question given this paragraph: The original rock is the source of the inorganic portion of the soil. Mechanical weathering breaks rock into smaller pieces. Chemical reactions change the rock's minerals. Q: Which type of weathering causes changes int he rocks materials, chemical or mechanical? Choices: - liquid - nuclear - mineral - chemical A:
**Answer**
chemical
Answer the following question given this paragraph: Electromagnetic waves differ in their wavelengths and frequencies. The higher the frequency of an electromagnetic wave, the greater its energy. The speed of an electromagnetic wave is the product of its wavelength and frequency, so a wave with a shorter wavelength has a higher frequency, and vice versa. Q: The speed of an electromagnetic wave is the product of its wavelength and what else? Choices: - height - resonance - density - frequency A:
frequency
