Answer the following question given this paragraph: Corals form large colonies in shallow tropical water. They are confined to shallow water because they have a symbiotic relationship with algae that live inside of them. The algae need sunlight for photosynthesis, so they must stay relatively close to the surface of the water to get enough light. Corals exist only as polyps. They catch plankton with their tentacles. Q: Coral and the algae living inside of them have what type of relationship, since the algae relies on the coral to stay close to the water's surface? Choices: - peculiar - competitive - parasitic - symbiotic A:
symbiotic
Answer the following question given this paragraph: Vertebrates reproduce sexually, and almost all have separate male and female sexes. Aquatic species generally have external fertilization, whereas terrestrial species usually have internal fertilization. Vertebrates have one of three reproductive strategies, known as ovipary, ovovivipary, or vivipary. Q: In what way do all vertebrates reproduce? Choices: - mitosis - asexually - biologically - sexually A:
sexually
Q: Answer the following question given this paragraph: Ginkgoes, like cycads, has separate female and male plants. The male trees are usually preferred for landscaping because the seeds produced by the female plants smell terrible when they ripen. Q: What is the most common plant-like protist? Choices: - mundane algae - invasive algae - esoteric algae - unicellular algae A:
A: unicellular algae
Question: Answer the following question given this paragraph: Weathering and erosion. Water, wind, ice, and even plants and animals all act to wear down rocks. Over time they can break larger rocks into smaller pieces called sediments. Moving water, wind, and glaciers then carry these pieces from one place to another. The sediments are eventually dropped, or deposited , somewhere. The sediments may then be compacted and cemented together. This forms a sedimentary rock. This whole process can take hundreds or thousands of years. Q: What is the term for the small particles that rocks are worn down to by water and wind? Choices: - fragments - pebbles - organisms - sediments A:
Answer: sediments

Answer the following question given this paragraph: Acceleration is the rate of change of velocity. So in other words, acceleration tells you how quickly the velocity is increasing or decreasing. An acceleration of indicates that the velocity is increasing by in the positive direction every second. Q: What is the rate of change of velocity called? Choices: - transmission - vibration - speed - acceleration A:
**Answer**
acceleration
Answer the following question given this paragraph: What happens if a substance needs assistance to move across or through the plasma membrane? Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient. Q: What do you call the diffusion of solutes through transport proteins in the plasma membrane? Choices: - necessitated diffusion - exposed diffusion - Osmosis - facilitated diffusion A:
facilitated diffusion
