Answer:
Scientists mostly gain new knowledge through direct observation and applying the scientific method. They would start with a hypothesis and test it, then change it or confirm it. Others would test their confirmation from one point, while the third group would test what the second said. And so on and so forth.
Explanation:
For the answer to the question above, p<span>unctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and rapid (on a geologic time scale) events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another.</span>
The answer is benedict’s reagent. Benedict’s
test is used to detect reducing sugars in solution when heated. The color
change occurs from clear blue to a brick-red precipitate in the presence of the
reducing sugars. The cupric compounds in
the benedicts reagent react with the reducing sugars (enediols) produced from
heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and
copper(II) sulfate pentahydrate.
Hormones are chemical substances that affect the activity of another part of the body. Hormones serve as messengers, controlling and coordinating activities throughout the body.
The endocrine gland produces hormones.
