Concept introduction: Science refers to the practical and intellectual activity going around the systematic study of behavior and structure of the natural and physical world through observation and experiment. The concept of science explains about the systematic and testable explanation about the universe.

Answer to Problem 1SQ
Correct answer: Scientific hypothesis is an educated guess explaining an observation. Therefore, option a. is correct answer.
Explanation of Solution
Reason for the correct statement:
Option a. is given as “an educated guess explaining an observation”.
Scientific hypothesis is a logical, informal, and plausible explanation for the observation of the natural world. This is often identified as the educated guess that seeks and describes the observed phenomenon. A fully explained scientific hypothesis is a clear-cut prediction that is necessary for testing the particular hypothesis.
Hence, option a. is the correct answer
Reasons for the incorrect statement:
Option b. is given as “a prediction based on an observation”. Prediction based observation have both positive and negative conclusion. But hypothesis needs particular conclusion. Hence, option b. is incorrect.
Option c. is given as “a scientific theory”. A scientific theory is a comprehensive explanation to prove a hypothesis, which is a predictive statement. It is based on a set of experiments and observations. Scientific theories can be revised upon the discovery of new data. Hence, option c. is incorrect.
Option d. is given as “an idea that can be proved beyond all doubt through experimentation.” Hypothesis is a reasoned prediction that is based on certain assumptions. It is a precise statement that needs to be tested with more observations and experiments. Hence, option d. is incorrect.
Hence, options b., c., and d. are incorrect.

- How much protein should Sarah add to her diet if she gets pregnant? Sarah's protein requirements during pregnancy would be higher. See Hint B2.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively. Separate the lower and upper range values, in that order, by a comma. ___, ___ g ?arrow_forwardC MasteringHealth MasteringNu X session.healthandnutrition-mastering.pearson.com/myct/itemView?assignment ProblemID=17396422&attemptNo=1&offset=prevarrow_forwardIf left untreated, most HIV-infected individuals will develop AIDS. Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables.
