Answer:
The term unicellular and multicellular describe how living things are organized.
Explanation:
The number of cells in living things determine how the body organization will be.
Living things are made up of cells in which there are two types of living cells. We have the unicellular and multicellular cells.
The unicellular are made up of one cell (single cell) the unicellular organisms are simple cells which make their functions simple while the multicellular organisms are made up of two or more organisms and their functions are special unlike the unicellular which the functions are simple

Complete question:
Biological polymers are produced by the process of __________, also known as __________. Choose two answers to fill in the blanks.
- dehydration synthesis
- condensation reactions
- hydrolysis reactions
- decomposition reactions
- hydrogenation reactions
Answer:
Biological polymers are produced by the process of dehydration synthesis, also known as condensation reactions.
Explanation:
The process of monomers union is known as Dehydration synthesis/condensation reactions. It refers to the formation of a polymer, by the union of many monomers, which also implicate <u>losing a water molecule</u> and using energy to occur. Every monomer has a free H atom and a hydroxyl group (-OH) in the extremes. When two monomers get together, the H atom and the -OH join to form a water molecule, which is released. The result is a polymer of two monomers and H₂O.
The opposite process is known as hydrolysis, which occurs when the polymer hydrates and releases monomers.
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
