Answer the following question given this paragraph: Transmembrane proteins span the entire plasma membrane. Their function is mainly to regulate the transport of specific molecules across the membrane. There are two basic types of transmembrane proteins, alpha-helical and beta-barrels, which are discussed in Organic Compounds: Proteins (Advanced) . Q: What proteins span the entire plasma membrane? Choices: - sequence - amino acids - cytoplasm - transmembrane A:
(Answer)
transmembrane
Ques: Answer the following question given this paragraph: The field of science has gotten so big that it is common to separate it into more specific fields. First, there is mathematics, the language of science. All scientific fields use mathematics to express themselvessome more than others. Physics and astronomy are scientific fields concerned with the fundamental interactions between matter and energy. Chemistry, as defined previously, is the study of the interactions of matter with other matter and with energy. Biology is the study of living organisms, while geology is the study of the earth. Other sciences can be named as well. Understand that these fields are not always completely separate; the boundaries between scientific fields are not always readily apparent. Therefore, a scientist may be labeled a biochemist if he or she studies the chemistry of biological organisms. Finally, understand that science can be either qualitative or quantitative. Qualitative implies a description of the quality of an object. For example, physical properties are generally qualitative descriptions: sulfur is yellow, your math book is heavy, or that statue is pretty. A quantitative description represents the specific amount of something; it means knowing how much of something is present, usually by counting or measuring it. As such, some quantitative descriptions would include 25 students in a class, 650 pages in a book, or a velocity of 66 miles per hour. Quantitative expressions are very important in science; they are also very important in chemistry. Q: What field of study is called the language of science? Choices: - logic - linguistics - physics - mathematics A:
Ans: mathematics

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:
(A).
chemical formulas
Ques:Answer the following question given this paragraph: Q: Transport epithelia that function in maintaining water balance also often function in disposal of what? Choices: - bacteria - absorption wastes - organisms wastes - metabolic wastes A:

Ans:metabolic wastes
Ques:Answer the following question given this paragraph: Another example of species loss due to habitat destruction happened on Madagascar's central highland plateau. From 1970 to 2000, slash-and-burn agriculture destroyed about 10% of the country's total native plants. The area turned into a wasteland. Soil from erosion entered the waterways. Much of the river ecosystems of several large rivers were also destroyed. Several fish species are almost extinct. Also, some coral reef formations in the Indian Ocean are completely lost. Q: What kind of agriculture destroyed about 10% of madagascar's native plants? Choices: - hybridization - crop rotation - fertilizer use - slash-and-burn A:

Ans:
slash-and-burn
