Answer: The size.
Explanation: On the one hand the Emperor Penguin is bigger reaching up to 48 Inches (120cm) of height and 100 Lb in weight, on the other hand the Galápagos Penguin is much smaller. For example a large adult usually goes up to 21 Inches (53cm) and 5 Lb of weight.
This is directly related to the temperature of the environment in which each one develops, because a body exchanges heat in two dimensions through the surface. So, it's easier for a big creature to maintain core temperature stable.
This is really important in environments like the Arctic where temperature goes below zero and the opposite happen in the Equator where there is a tropical weather all the time.
The emergence of resistance is a result of EVOLUTION by natural selection. It is a major evolutionary force.
<h3>Evolution and natural selection </h3>
The term evolution refers to the biological process of descendence with modification.
Natural selection refers to the differential survival or reproduction of the organisms better adapted to a given environment.
In this case, the presence of the pesticide generates an evolutionary constraint, thereby selecting pesticide-resistant individuals in the population.

Answer:
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?
The correct answear is B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
Explanation:
Naltrexone is a non-selective opioid antagonist, it competes with these at the level of the receptors and thus reduces their effects.
The responses A, C, D and E does not weaken the support for the
researches ´ predictions, and are not relevant to the argument.
Answer:
The open area where the substrate is attached to an enzyme is called the active site.
Explanation:
The active site of an enzyme corresponds to the place where the tertiary structure of this molecule leaves a free space to couple the substrate and be able to catalyze a chemical reaction.
Since the enzyme-substrate complex functions as a <u>key lock system</u>, the active site has a three-dimensional configuration that only admits certain molecules as substrate, which determines its specificity.
