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: Organs may be organized into organ systems. An organ system is a group of organs that work together to do the same job. For example, the heart is part of the cardiovascular system. This system also includes blood vessels and blood. The job of the cardiovascular system is to transport substances in blood to and from cells throughout the body. Q: What is a group of organs that work together to do the same job? Choices: - an organ colony - an organ assembly - an organ battery - an organ system A:
(Answer)
an organ system
Ques: Answer the following question given this paragraph: Neutralization reactions between an acid and a base yield a salt and water. In some cases, this results in a completely neutral solution. However, some salts are weakly acidic or basic. How can we tell whether a given salt will act as an acid or base? Looking at the relative strengths of the acid and base that were used to form the salt can give us information on the acid-base properties of the resulting solution. Q: What kind of reactions between an acid and a base yield a salt and water? Choices: - oxidation - evaporation - distillation - neutralization A:
Ans: neutralization
(Q).
Answer the following question given this paragraph: Section Summary 11.1 What Is a Fluid? A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids. Q: What is the term for a state of matter that yields to sideways or shearing forces? Choices: - gravity - solid - plasma - fluid A:
(A).
fluid
Ques:Answer the following question given this paragraph: A liquid is a form of matter that has a definite volume, but an indefinite shape. As water is poured from one container into another, it adopts the shape of its new container. However, the volume of the water does not change, because the water molecules are still relatively close to one another in the liquid state. Unlike a solid, the arrangement of particles in a liquid is not rigid and orderly. Liquids are also incompressible. Q: What is a form of matter that has a definite volume, but an indefinite shape? Choices: - a solid - a plasma - a gas - a liquid A:

Ans:a liquid
Question: Answer the following question given this paragraph: The epidermis is the outermost layer of the skin. It forms the waterproof, protective wrap over the body's surface. Although the top layer of epidermis is only about as thick as a sheet of paper, it is made up of 25 to 30 layers of cells. The epidermis also contains cells that produce melanin. Melanin is the brownish pigment that gives skin and hair their color. Melanin-producing cells are found in the bottom layer of the epidermis. The epidermis does not have any blood vessels. The lower part of the epidermis receives blood by diffusion from blood vessels of the dermis. Q: What is the outermost layer of the skin? Choices: - dermis - nexus - callus - epidermis A:
Answer:
epidermis
