Example 1:

Endoplasmic reticulum (ER) are like factories of cells. If we consider cell as a international clothing chain of companies, then ER are the ones which plan and design the clothing, sew those up, put additional buttons etc. on them, and then ship them on time. The workers (manual and automatic) do the whole procedure.

To understand it better in terms of cellular functions, ER create biomolecules essential for cells and the body as a whole. ribosomes are the workers which do the synthesis. With the help of ribosomes, ER makes the whole process of biomolecule synthesis, modification and delivery smooth, efficient and accurate.

Example 2:

Think of ER as Uber Eats. It provides you the catalogue of delicious food available and can be sent, then forwards your request to the restaurant, then sends a delivery person to wait and collect the order, and then orders the person to delivery food to the correct address on time.

Here, ribosomes would be the restaurants making the food.

**This is a simplification of the actual function of ER but I hope you get the gist. While talking about smooth and rough ER, the examples may change.

Identify each adaptation as structural or behavioral adaptations.
Zina [86]

Answer:

Monkeys have a prehensile tail that allows them to grab and hold onto tree branches - structural

Moose make mating calls to locate potential mates - behavioral

Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters - structural

Humans have five toes on each foot to help them maintain balance - structural

Many birds migrate south for the winter in search of food - behavioral

Explanation:

The structural adaptations are adaptations that help the organisms to survive in their environment through development of physical traits that give them an advantage. Such adaptations are the thick layer of blubber of the whales, the five toes of the humans, prehensile tail of the monkeys, rotational toe of the clouded leopard, long of the giraffe etc. The behavioral adaptations are adaptations that help the organisms to survive in their environment, but they manifested through their actions, not their physical traits. Such adaptations are the mating calls of the moos, the migration of the birds in winter, the hibernation of the bears etc.
