Answer the following question given this paragraph: Below the topsoil is the "B" horizon. This is also called the subsoil . Soluble minerals and clays accumulate in the subsoil. Because it has less organic material, this layer is lighter brown in color than topsoil. It also holds more water due to the presence of iron and clay. There is less organic material in this layer. Q: Soluble minerals and clays accumulate in what soil layer, allowing it to hold more water? Choices: - silt - subsurface - topsoil - subsoil A:
subsoil

Answer the following question given this paragraph: contain the carbonyl functional group (C=O; part (a) in Figure 24.14 "The Oxidation State of Carbon in Oxygen- and Nitrogen-Containing Functional Groups"). Alcohols are classified as primary, secondary, or tertiary, depending on whether the OH group is bonded to a primary, secondary, or tertiary carbon. For example, the compound 5-methyl-3-hexanol is a secondary alcohol. Q: The bending of a wave around the edges of an opening or an obstacle is called this? Choices: - reflection - sputtering - absorption - diffraction A:
(Answer)
diffraction
Ques: Answer the following question given this paragraph: The small intestine is a narrow tube that starts at the stomach and ends at the large intestine. In adults, it's about 7 meters (23 feet) long. Most chemical digestion and almost all nutrient absorption take place in the small intestine. Q: What is the name of the narrow tube that begins at the stomach and ends at the large intestine? Choices: - small stomach - pancreas - small tissues - small intestine A:

Answer the following question given this paragraph: Immunologist The variations in peripheral proteins and carbohydrates that affect a cell's recognition sites are of prime interest in immunology. These changes are taken into consideration in vaccine development. Many infectious diseases, such as smallpox, polio, diphtheria, and tetanus, were conquered by the use of vaccines. Immunologists are the physicians and scientists who research and develop vaccines, as well as treat and study allergies or other immune problems. Some immunologists study and treat autoimmune problems (diseases in which a person's immune system attacks his or her own cells or tissues, such as lupus) and immunodeficiencies, whether acquired (such as acquired immunodeficiency syndrome, or AIDS) or hereditary (such as severe combined immunodeficiency, or SCID). Immunologists are called in to help treat organ transplantation patients, who must have their immune systems suppressed so that their bodies will not reject a transplanted organ. Some immunologists work to understand natural immunity and the effects of a person's environment on it. Others work on questions about how the immune system affects diseases such as cancer. In the past, the importance of having a healthy immune system in preventing cancer was not at all understood. To work as an immunologist, a PhD or MD is required. In addition, immunologists undertake at least 23 years of training in an accredited program and must pass an examination given by the American Board of Allergy and Immunology. Immunologists must possess knowledge of the functions of the human body as they relate to issues beyond immunization, and knowledge of pharmacology and medical technology, such as medications, therapies, test materials, and surgical procedures. Q: What is the term for physicians and scientists who research and develop vaccines and treat and study conditions ranging from allergies to aids? Choices: - endocrinologists - vaccinologists - virologists - immunologists A:
(A).
immunologists
Ques:Answer the following question given this paragraph: Recall that ecology is the study of how living organisms interact with each other and with their environment. But how do organisms interact with each other? Organisms interact with each other through various mechanisms, one of which is competition. Competition occurs when organisms strive for limited resources. Competition can be for food, water, light, or space. This interaction can be between organisms of the same species (intraspecific) or between organisms of different species (interspecific). Q: What is the study of how living organisms interact with each other and with their environment? Choices: - botany - zoology - genetics - ecology A:

Ans:ecology
