Question: Which phrase defines a law?
A. a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable
B. A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
C. a hypothesis or group of related hypotheses that can be accepted as true based on repeated experimentation with similar results
Answer:
Correct answer: B). A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
Explanation:
A scientific law may be defined as the something that appears to be true and is universally applicable. Scientific laws do not explain why the observed events happen, but it only states that the event occurs in the same way over and over. Example of scientific law is a law of gravity. Gravity is always there and it always works in the same manner. Other examples include newton's law of motion, which states how the things move.
Answer:
The scaling exponent will be 0.75
Explanation:
According to a famous article by Max Kleiber*, the scaling of the metabolic rate or energy consumption for mammals Pmetab (measured in kcal/day) with the body mass Mb (measured in kilograms) is P metab = 70 Mb^0.75 .
What is the scaling exponent (the quantity x in a scaling law A = cMbx) for the specific metabolic rate as a function of the animal’s body mass?
he scaling of the metabolic rate or energy consumption for mammals P=kcal/day
Mb=body mass in kilograms
Comparing
P metab = 70 Mb^0.75 .
with A = cMb^x
the scaling exponent will be 0.75
metabolic rate is the energy(in kilojoule) consumed at rest. it accounts for the highest amount of energy a body consumes daily
