Read this paragraph and choose the correct option from the provided answers: The human skeleton is an endoskeleton that consists of 206 bones in the adult. It has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and allowing for movement. The skeletal system in vertebrates is divided into the axial skeleton (which consists of the skull, vertebral column, and rib cage), and the appendicular skeleton (which consists of the shoulders, limb bones, the pectoral girdle, and the pelvic girdle). Choices: - Forward movement - enough movement - more movement - allowing movement A:
A: allowing movement

Q: Q: What term describes the overall ability of an animal to survive and produce offspring? Read this paragraph and choose the correct option from the provided answers: Animal communication, like most other animal behaviors, increases the ability to survive and have offspring. This is known as fitness. Communication increases fitness by helping animals find food, defend themselves from predators, mate, and care for offspring. Choices: - change - evolution - abilities - fitness A:
A: fitness

Q: Q: What type of bond generally forms between a metal and non-metal? Read this paragraph and choose the correct option from the provided answers: Ionic bonds form only between metals and nonmetals. That's because metals "want" to give up electrons, and nonmetals "want" to gain electrons. Find sodium (Na) in the Figure below . Sodium is an alkali metal in group 1. Like all group 1 elements, it has just one valence electron. If sodium loses that one electron, it will have a full outer energy level, which is the most stable arrangement of electrons. Now find fluorine (F) in the periodic table Figure below . Fluorine is a halogen in group 17. Like all group 17 elements, fluorine has seven valence electrons. If fluorine gains one electron, it will also have a full outer energy level and the most stable arrangement of electrons. Choices: - soluble - unbreakable - horizontal - ionic A:
A: ionic

Q: Q: What do you call a predator species that affects other species' populations when its own population size changes? Read this paragraph and choose the correct option from the provided answers: Some predator species play a special role in their community. They are called keystone species. When the population size of a keystone species changes, the populations of many other species are affected. Prairie dogs, pictured in Figure below , are an example of a keystone species. Their numbers affect most of the other species in their community. Prairie dog actions improve the quality of soil and water for plants, upon which most other species in the community depend. Choices: - paradox species - symbiotic species - complement species - keystone species A:
A: keystone species
