Answer the following question given this paragraph: Minerals Minerals in food are inorganic compounds that work with other nutrients to ensure the body functions properly. Minerals cannot be made in the body; they come from the diet. The amount of minerals in the body is smallonly 4 percent of the total body massand most of that consists of the minerals that the body requires in moderate quantities: potassium, sodium, calcium, phosphorus, magnesium, and chloride. The most common minerals in the body are calcium and phosphorous, both of which are stored in the skeleton and necessary for the hardening of bones. Most minerals are ionized, and their ionic forms are used in physiological processes throughout the body. Sodium and chloride ions are electrolytes in the blood and extracellular tissues, and iron ions are critical to the formation of hemoglobin. There are additional trace minerals that are still important to the body's functions, but their required quantities are much lower. Like vitamins, minerals can be consumed in toxic quantities (although it is rare). A healthy diet includes most of the minerals your body requires, so supplements and processed foods can add potentially toxic levels of minerals. Table 24.5 and Table 24.6 provide a summary of minerals and their function in the body. Q: What is critical for the formation of hemoglobin? Choices: - salts - proteins - platelets - iron ions A:
iron ions

Answer the following question given this paragraph: Although it is not found in the skull, the hyoid bone is considered a component of the axial skeleton. The hyoid bone lies below the mandible in the front of the neck. It acts as a movable base for the tongue and is connected to muscles of the jaw, larynx, and tongue. The mandible articulates with the base of the skull. The mandible controls the opening to the airway and gut. In animals with teeth, the mandible brings the surfaces of the teeth in contact with the maxillary teeth. The Vertebral Column The vertebral column, or spinal column, surrounds and protects the spinal cord, supports the head, and acts as an attachment point for the ribs and muscles of the back and neck. The adult vertebral column comprises 26 bones: the 24 vertebrae, the sacrum, and the coccyx bones. In the adult, the sacrum is typically composed of five vertebrae that fuse into one. The coccyx is typically 34 vertebrae that fuse into one. Around the age of 70, the sacrum and the coccyx may fuse together. We begin life with approximately 33 vertebrae, but as we grow, several vertebrae fuse together. The adult vertebrae are further divided into the 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae (Figure 38.8). Q: What controls the opening to the airway and gut? Choices: - tongue - teeth - electrons - mandible A:
(Answer)
mandible

We also know that the Sun is not the center of the universe. But it is the center of the solar system. Q: What is considered the center of the solar system? Choices: - nebulla - earth - heat - sun A:

70 ml
Ques:Answer the following question given this paragraph: Because of their freely moving electrons, metals are good conductors of electricity. Metals also can be shaped without breaking. They are ductile (can be shaped into wires) and malleable (can be shaped into thin sheets). Metals have these properties because of the nature of their metallic bonds. Q: The nature of what gives metals the properties of being ductile and malleable? Choices: - liquid bonds - magneticism - titanium bonds - metallic bonds A:

Ans:metallic bonds
Answer the following question given this paragraph: Parallel electrical circuits have multiple paths the current may take. Q: What type electrical circuits have multiple paths the current may take? Choices: - perpendicular - single loop - serial - parallel A:
parallel
