an enzyme
The diagram below represents changes that take place within the human body. The diagram represents
dynamic equilibrium
The setup below shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail. Which compound that directly provides energy in living cells is being produced in every tube where cellular respiration is occurring?
ATP
Which statement regarding respiration is correct?
All living organisms carry out some form of respiration.
The delivery of oxygenated blood to all tissues around the body involves what two life functions?
Respiratory and circulatory
The diagram below represents a sequence of events that occurs in the human body throughout the day. These events can best be described as an example of
a feedback mechanism
Which row in the chart below contains correct information concerning synthesis?
amino acids, enzyme
Which system in a multicellular organism functions most like the cytoplasm in a single celled organism?
circulatory
ATP is a compound that is synthesized when
energy stored in chemical bonds is released during cellular respiration
In the diagram to the right, the arrows show the direction of movement of various substances. Which of the cell's life activities are represented by the arrows?
excretion, transport, and respiration
A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rests in a shady area until its body temperature cools. This type of behavior is important to
maintain homeostasis
The breathing rate, heart rate, and blood hormone levels of an individual would directly provide information about that individual's
metabolic activity
Which term is defined as all the chemical reactions that are required to sustain life?
metabolism
Homeostasis is maintained in a single-celled organism by the interaction of
organelles
Which process is a form of autotrophic nutrition?
photosynthesis
Which group contains only molecules that are each assembled from smaller organic compounds?
proteins, DNA, fats, starch

respiratory
In which process are simple materials chemically combined to form more complex materials?
synthesis
The setup below shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail. In this setup, which tubes contain at least one organism carrying on cellular respiration?
tubes 2, 3, and 4, only
the diagrams below and on your knowledge of biology. The diagrams represent some of the systems that make up the human body. A similarity between these systems is that they all
work together to maintain a stable internal environment
