It is a scientific law
Explanation:
A scientific law states a constant relationship between two or more variables, each of which represents a property or measurement of specific systems. It is a constant and unchanging rule, usually expressed mathematically which allows to predict the unknown based on what is known with logical and real relationships.
A scientific theory is a set of concepts and rules (scientific laws) that express the relationships between observations of such concepts and generates a principle or set of principles to explain a phenomenon.
Blood pressure
This is indicated in Starling's Hypothesis in which there is fluid movement due to filtration across the wall of capillary. This is dependent between hydrostatic pressure gradient and oncotic pressure across the capillary. The balance of these forces allow the net driving pressure for filtration. The net fluid influc is proportional to this net driving pressure. The leakage of proteins across the capillary membrane has important effects and has corresponding cause in the balance of forces.
The fish are eaten by ducks. Ducks cannot really swallow preys that are too big for their throats. They usually swallow organisms that are a lot smaller than fishes. because they do not have the capacity to bite and chew their preys.
The answer has to be option B "testable." A hypothesis is a educated guess on what you think is going to happen during a experiment. Also its not going to be option A because a hypothesis doesn't exactly have to be written homeschool students have there instructions on a computer in order to be completed. Its not option C because a hypothesis has the have its test variables. (independent & dependent variables) Its also not option D because some scientists conduct their experiments by themselves.
Hope this helps!
