Q: When a species always migrates, what is this type of migration called? Read this paragraph and choose the correct option from the provided answers: Although migration is thought of as innate behavior, only some migrating species always migrate (obligate migration). Animals that exhibit facultative migration can choose to migrate or not. Additionally, in some animals, only a portion of the population migrates, whereas the rest does not migrate (incomplete migration). For example, owls that live in the tundra may migrate in years when their food source, small rodents, is relatively scarce, but not migrate during the years when rodents are plentiful. Foraging Foraging is the act of searching for and exploiting food resources. Feeding behaviors that maximize energy gain and minimize energy expenditure are called optimal foraging behaviors, and these are favored by natural section. The painted stork, for example, uses its long beak to search the bottom of a freshwater marshland for crabs and other food (Figure 45.36). Choices: - emigration - genus migration - mass migration - obligate migration A:
obligate migration

Q: What is the term for a disease that is not contagious? Read this paragraph and choose the correct option from the provided answers: Not all diseases are contagious. A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases. Choices: - uncultured disease - common cold - benign - noninfectious disease A:
noninfectious disease

Q: Q: Sodium-potassium pumps help nerve cells establish a voltage across their what? Read this paragraph and choose the correct option from the provided answers: Choices: - potassium membranes - sodium membranes - cell walls - plasma membranes A:
A: plasma membranes

Question: Q: What distinguishing characteristic of annelid anatomy shows specialization and adaptation? Read this paragraph and choose the correct option from the provided answers: Annelids are divided into many repeating segments. The earthworm in Figure below is an annelid. You can clearly see its many segments. Segmentation of annelids is highly adaptive. Each segment has its own nerve and muscle tissues. This allows the animal to move very efficiently. Some segments can also be specialized to carry out particular functions. They may have special structures on them. For example, they might have tentacles for sensing or feeding, "paddles" for swimming, or suckers for clinging to surfaces. Choices: - asymmetry - beautiful - compression - segmentation A:
Answer: segmentation

Q: Because complex plant carbohydrates such as cellulose are more difficult to digest, what animal diet is associated with a complicated digestive system? Read this paragraph and choose the correct option from the provided answers: Different diets require different types of digestive systems. Mammals that eat a carnivorous diet generally have a relatively simple digestive system. Their food consists mainly of proteins and fats that are easily and quickly digested. Herbivorous mammals, on the other hand, tend to have a more complicated digestive system. Complex plant carbohydrates such as cellulose are more difficult to digest. Some herbivores have more than one stomach. The stomachs store and slowly digest plant foods. Choices: - polyvore - omnivore - carnivore - herbivore A:
**Answer**
herbivore

Q: In physics, work means the use of what to move an object? Read this paragraph and choose the correct option from the provided answers: Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teens who are playing basketball in the picture above are using force to move their bodies and the basketball, so they are doing work. The teen who is studying isn't moving anything, so she isn't doing work. Not all force that is used to move an object does work. For work to be done, the force must be applied in the same direction that the object moves. If a force is applied in a different direction than the object moves, no work is done. The Figure below illustrates this point. Choices: - mass - energy - leverage - force A:
force
