Stomach with rugae
Rugae are sets of ridges formed by
folding of the wall of an organ. The stomach rugae exist in the mucosal and
submucosal layers of the stomach. They function through the action of
mechanoreceptors which provide contraction and allow the stomach to expand when
a bolus enters it. By this action, there is increase in the surface area of the
stomach for nutrient absorption during digestion.
Answer:
A testable hypothesis is valuable, even if evidence shows that it is false
Explanation:
A hypothesis sets a base on which the experiment is conducted by determining the design and protocol for which the scientists will take in the experiment. A hypothesis, therefore, should be developed based on good research prior to beginning to conduct the experiment. Usually a good hypothesis is one of no change called a 'null hypothesis'. Based on an analysis of data from the experiment, a hypothesis could either be rejected or accepted. If the null hypothesis is rejected then the alternative - which is usually the flip side of the null hypothesis- is adopted as true.
