step 1: respond to the following:

suppose after a high-smog alert day in your city, a 5-year-old child with asthma, a 50-year-old male
smoker with emphysema, and a 75-year-old of average health all come to the emergency room
complaining of a cough and chest pain.
rces
• which patient's health would you be the most concerned about and why?
how do breathed-in air pollutants, such as smoke or asbestos, interfere with or worsen the
respiration process in each of these scenarios?
refer to the textbook and the internet as needed to find this information and support your
responses to these questions.

Their supporting structure would be most likely the MUSCULOSKELETAL SYSTEM of the multicellular organisms.

Explanation:

The musculoskeletal system found in multicellular organisms are made up of structures which provides support, protection and allows for various movements. These structures include:

--> Muscles

--> Cartilage

--> Ligaments

--> Tendons and

--> Joints

Furthermore, Microtubules and microfilaments are the major components of cytoskeleton. They are the structures that gives a cell it's shape and helps organise it's parts. As described in the question, they are elongated structures that cross the cell, giving SUPPORT to the cell, and carries organelles and objects throughout the cell.

Therefore, since the Microfilaments and Microtubules provides support and shape at the cellular level it can be most likened to the musculoskeletal system of multicellular organisms which performs the same functions.
