Answer the following question given this paragraph: A balanced chemical equation provides a great deal of information in a very succinct format. Chemical formulas provide the identities of the reactants and products involved in the chemical change, allowing classification of the reaction. Coefficients provide the relative numbers of these chemical species, allowing a quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction. These quantitative relationships are known as the reaction's stoichiometry, a term derived from the Greek words stoicheion (meaning "element") and metron (meaning "measure"). In this module, the use of balanced chemical equations for various stoichiometric applications is explored. The general approach to using stoichiometric relationships is similar in concept to the way people go about many common activities. Food preparation, for example, offers an appropriate comparison. A recipe for making eight pancakes calls for 1 cup pancake mix, 3 cup milk, and one egg. The "equation" representing the preparation of 4 pancakes per this recipe is 1 cup mix + 3 cup milk + 1 egg 8 pancakes 4 If two dozen pancakes are needed for a big family breakfast, the ingredient amounts must be increased proportionally according to the amounts given in the recipe. For example, the number of eggs required to make 24 pancakes is 24 pancakes . Q: What provides the identities of the reactants and products involved in the chemical change? Choices: - electron shells - genome sequence - atomic numbers - chemical formulas A:
chemical formulas
Answer the following question given this paragraph: The most obvious landforms created by lava are volcanoes. These are mostly cinder cones, composite volcanoes, and shield volcanoes. Eruptions also take place through other types of vents, commonly from fissures ( Figure below ). The eruptions that created the entire ocean floor are essentially fissure eruptions. Q: Which type of eruptions created the entire ocean floor? Choices: - formation eruptions - fault eruptions - lava effusion - fissure eruptions A:
fissure eruptions
Q: Answer the following question given this paragraph: Other types of flatworms are parasitic. That means they live inside another organism, called a host, in order to get the food and energy they need. For example, tapeworms have a head-like area with tiny hooks and suckers (known as the scolex ) that help the worm attach to the intestines of an animal host ( Figure below ). There are over 11,000 species of parasitic flatworms. Q: What does parasitic mean? Choices: - mutual benefit - welcome guest - symbiotic - lives in host A:
A: lives in host
Question: Answer the following question given this paragraph: Courtesy of the U. S. National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) Program. Lymph capillaries collect the flood the leaks from blood capillaries and is slowly returned to the cardiovascular system . Q: Lymph capillaries collect the fluid that leaks from blood capillaries and slowly return it to what system? Choices: - muscular - circulatory - gastrointestinal - cardiovascular A:
Answer: cardiovascular

Answer the following question given this paragraph: Immunodeficiency Immunodeficiency is a failure, insufficiency, or delay in the response of the immune system, which may be acquired or inherited. Immunodeficiency can allow pathogens or tumor cells to gain a foothold and replicate or proliferate to high enough levels so that the immune system becomes overwhelmed. Immunodeficiency can be acquired as a result of infection with certain pathogens that attack the cells of the immune system itself (such as HIV), chemical exposure (including certain medical treatments such as chemotherapy), malnutrition, or extreme stress. For instance, radiation exposure can destroy populations of lymphocytes and elevate an individual's susceptibility to infections and cancer. Rarely, primary immunodeficiencies that are present from birth may also occur. For example, severe combined immunodeficiency disease (SCID) is a condition in which children are born without functioning B or T cells. Q: What term means a failure, insufficiency, or delay in the response of the immune system, which may be acquired or inherited? Choices: - anemia - pathogenic - vitamin deficiency - immunodeficiency A:
**Answer**
immunodeficiency

Answer the following question given this paragraph: Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons. For example, they provide neurons with nutrients and other materials. Q: Nervous tissue consists of just two basic types of nerve cells: neurons and? Choices: - white blood cells - red blood cells - mammalian cells - glial cells A:
(A).
glial cells
