Answer the following question given this paragraph: The study of rock layers is called stratigraphy. Laws of stratigraphy help scientists determine the relative ages of rocks. The main law is the law of superposition. This law states that deeper rock layers are older than layers closer to the surface. Q: What do we call the study of rock layers? Choices: - geology - mineralogy - sedimentary - stratigraphy A:
(Answer)
stratigraphy

Answer the following question given this paragraph: Human Metabolism and the First Law of Thermodynamics Human metabolism is the conversion of food into heat transfer, work, and stored fat. Metabolism is an interesting example of the first law of thermodynamics in action. We now take another look at these topics via the first law of thermodynamics. Considering the body as the system of interest, we can use the first law to examine heat transfer, doing work, and internal energy in activities ranging from sleep to heavy exercise. What are some of the major characteristics of heat transfer, doing work, and energy in the body? For one, body temperature is normally kept constant by heat transfer to the surroundings. This means Q is negative. Another fact is that the body usually does work on the outside world. This means then, the body loses internal energy, since. Q: Human metabolism is the conversion of food into heat transfer, work, and this? Choices: - stored atp - stored carbs - stored protein - stored fat A:
(A).
stored fat
Ques:Answer the following question given this paragraph: Polysaccharides are long carbohydrate molecules of repeated monomer units joined together by glycosidic bonds. A polysaccharide may contain anywhere from a few monosaccharides to several thousand monosaccharides. Polysaccharides are also called complex carbohydrates . Polysaccharides have a general formula of C x (H2O) y , where x is usually a large number between 200 and 2500. Considering that the repeating units in the polymer backbone are often six-carbon monosaccharides, the general formula can also be represented as (C 6 H 10 O 5 ) n , where 40n3000. Q: What is the term for long carbohydrate molecules of repeated monomer units joined together by glycosidic bonds? Choices: - fibres - template strands - hydrocarbons - polysaccharides A:

Ans:polysaccharides
Question: Answer the following question given this paragraph: Figure 7.10 Cations are formed when atoms lose electrons, represented by fewer Lewis dots, whereas anions are formed by atoms gaining electrons. The total number of electrons does not change. Q: What are formed by atoms gaining electrons? Choices: - ions - cations - oxides - anions A:
Answer:
anions
