The pair that incorrectly matches polymer-monomer is lipids-monosaccharides (option C).
<h3>What is a monomer?</h3>
A monomer is a small molecule which can be covalently bonded to other monomers to form a polymer.
A polymer, on the other hand, is a large molecule made up of a chain of many monomeric units, formed by chemically bonding together.
The following are the monomer-polymer combination we have in nature;
- Carbohydrates - simple sugar/monosaccharide
- Protein - amino acid
- Lipids - fatty acid
- Nucleic acid - nucleotide
Therefore, the pair that incorrectly matches polymer-monomer is lipids-monosaccharides.

Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.

Answer:
smelling rotten eggs - covering your nose
touching a hot dish - pulling your hand away
jumping into a cold pool - shivering
Explanation:
<u>A stimulus generally refers to a detectable change in the environment of an organism. These changes could be physical or chemical and could be in the internal or external environment of organisms. </u>
Organisms react to changes in their internal or external environment by responding appropriately. Hence perceiving the smell of rotten egg, feeling the hotness of a dish by touching it, and feeling cold immediately one jumps into a cold pool are all examples of stimuli and their corresponding responses would be covering one's nose, pulling the hand away, and shivering of the body in order to counter the cold.
In other words:
<em>smelling rotten eggs - covering your nose</em>
<em>touching a hot dish - pulling your hand away</em>
<em>jumping into a cold pool - shivering</em>
Answer:
Proteins
Explanation:
They are found everywhere in the body from muscle, cell membranes, hair, enzymes, and etcetera and are responsible for the phenotype of organisms. Proteins are the ultimate expression of genes in the DNA of organisms. The DNA is transcribed by DNA polymerase into mRNA, then mRNA is translated into protein by ribosomes. This general rule is called the central dogma.
