Answer: A law in science is a generalized rule to explain a body of observations in the form of a verbal or mathematical statement. Scientific laws (also known as natural laws) imply a cause and effect between the observed elements and must always apply under the same conditions.
Explanation:
Examples of scientific laws (also called “laws of nature”) include the laws of thermodynamics, Boyle's law of gasses, the laws of gravitation. ... A law is used to describe an action under certain circumstances. For example, evolution is a law — the law tells us that it happens but doesn't describe how or why.
Answer:
C
Explanation:
The main mechanisms of homeostasis are body temperature, body fluid composition, blood sugar, gas concentrations, and blood pressure. These are all things that involve "keeping a relatively constant internal environment in the body".
Answer:
C. Natural selection favors individuals that reproduce more than others.
Explanation:
Genetic variations present in the population are acted upon by natural selection. The organisms that have the adaptive traits which in turn make them able to survive and reproduce more than the other individuals are favored by natural selection.
Over generations, natural selection leads to the evolution of a new population with an increased frequency of the gene responsible for the selected adaptive trait.
For example, the bacteria with antibiotic resistance were favored by natural selection as they can survive and produce more progeny in the presence of antibiotics than the bacteria lacking the gene for antibiotic resistance.
