Q: When a predator kills and eats its prey, what sort of predation is this referred to as? Read this paragraph and choose the correct option from the provided answers: True predation is when a predator kills and eats its prey. Some predators of this type, such as jaguars, kill large prey. They tear it apart and chew it before eating it. Others, like bottlenose dolphins or snakes, may eat their prey whole. In some cases, the prey dies in the mouth or the digestive system of the predator. Baleen whales, for example, eat millions of plankton at once. The prey is digested afterward. True predators may hunt actively for prey, or they may sit and wait for prey to get within striking distance. Certain traits enable organisms to be effective hunters. These include camouflage, speed, and heightened senses. These traits also enable certain prey to avoid predators. Choices: - false - just - predestined - true A:
true

Q: Scientists found that the youngest rocks on the seafloor were where? Read this paragraph and choose the correct option from the provided answers: The scientists used geologic dating techniques on seafloor rocks. They found that the youngest rocks on the seafloor were at the mid-ocean ridges. The rocks get older with distance from the ridge crest. The scientists were surprised to find that the oldest seafloor is less than 180 million years old. This may seem old, but the oldest continental crust is around 4 billion years old. Choices: - trenches. - mid - ocean sediments - mid - ocean glaciers - mid-ocean ridges A:
mid-ocean ridges

Q: What is the term for when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype? Read this paragraph and choose the correct option from the provided answers: Gap genes themselves are under the effect of maternal effect genes, such as bicoid and nanos. Gap genes also regulate each other to achieve their precise striped expression patterns. The maternal effect is when the phenotype of offspring is partly determined by the phenotype of its mother, irrespective of genotype. This often occurs when the mother supplies mRNA or proteins to the egg, affecting early development. In developing Drosophila, maternal effects include axis determination. Choices: - congenital effect - uterine effect - oceanic effect - maternal effect A:
maternal effect

Q: Desert plants have special stems and leaves to conserve what? Read this paragraph and choose the correct option from the provided answers: Each organism has the ability to survive in a specific environment. Dry desert environments are difficult to live in. Desert plants have special stems and leaves to conserve water. Animals have other ways to live in the desert. The Namib Desert receives only 1.5 inches of rainfall each year. The Namib Desert beetle lives there. How do the beetles get enough water to survive? Early morning fog deposits water droplets. The droplets collect on a beetle's wings and back. The beetle tilts its rear end up. When the droplet is heavy enough, it slides forward. It lands in the beetle's mouth. There are many other environments that need unique approaches for survival ( Figure below ). Choices: - food - air - habitat - water A:
water
