Answer:
Mimicry
Explanation:
Living organisms are known to be able to adapt to the natural environment in which they exist over time. One of the adaptation techniques is called MIMICRY. Mimicry is a type of physical adaptation whereby an organism (animal) looks similar in appearance to another organism in order to discourage or push away predators.
This is the case of the viceroy butterfly in this question, which has coloration that is almost identical to the poisonous monarch butterfly. Although, the viceroy butterfly is not poisonous but its coloration that looks like poisonous monarch butterfly makes it appear poisonous to predators. Viceroy butterfly is said to mimick the poisonous monarch butterfly in order to deceive predators.

Answer:
In the Middle Ages, spices that are now ordinary were rare imports from faraway places.
Explanation:
The central idea of the text can be defined by the excerpt above.
The text is explaining the process that Italian merchants had to go through in order to carry a expensive spice (pepper) from Syria to the fairs of Champagne, in France.
This is because spices were a very well-regarded and expensive product that could only be afforded by the wealthy at the time, since shipping methods at the time were primitive (slow ships, camels), raising the cost of these products to levels that would be hard to imagine today.
The length of an arc rounded to the nearest hundredth is 4.75units
<h3>How to calculate the length of an arc?</h3>
The formula for calculating the length of an arc is expressed as:
L = rtheta
where
r is the radius = AB = 4 units
theta is the central angle = <ABC = 68 degrees
Substitute
L = 4(68π/180)
L = 4.75units
Hence the length of an arc rounded to the nearest hundredth is 4.75units
