Answer: unfavourable ph condition for the pepsin
Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .
As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.
In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.
As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
Answer: mathematics
Explanation:
Mathematics is the study of quantity, space, structure of a concerned entity or population size. A scientific experiment may be based on the analysis of variables must be having large sample size. Therefore, quantitative estimation of the results is required. Hence, a scientist requires mathematics to interpret the results of a scientific experiment.
A light year is the distance traveled by light in a year.
