Characteristics of Life
A student is performing an experiment that includes measuring the level of glucose in their blood. A measurement taken just before eating lunch and one taken three hours after eating a carbohydrate‐rich lunch are very similar.
What is homeostasis?
This is the name for electrons found on the outermost shell.
What is valence?
This macromolecule is responsible for providing immediate energy, sometimes in quick bursts.
What is carbohydrate?
The name given to the outputs of an enzymatic reaction.
What is products?
This describes an organism's ability to maintain stable internal conditions.
What is homeostasis?
Paramecia are single‐celled organisms which use a process called mitosis to make identical copies of themselves.
What is reproduction?
The atomic number of an element represents the amount of this subatomical particle in the nucleus.
What is protons?
This macromolecule is responsible for the regulation of chemical reactions and hormonal control, among other functions.
What is protein?
An enzyme belongs to this class of macromolecule.
What is protein?
This defines a change from normal or stable conditions.
What is stimulus?
Fennec foxes are desert‐dwelling canines that have ears which are far larger in proportion to their bodies than other species of dogs, foxes, and wolves. These oversized ears allow for rapid heat transfer in their hot environments,
What is adaptation? (or evolution)
This is the name for a molecule that has been chemically combined.
What is compound?
This macromolecule is used to store energy for later use, as well as make up the majority of cell membranes.
What is lipid?
The name given to the inputs of an enzymatic reaction.
What is substrates?
The kidneys sense that the oxygen levels in the blood are too low. The kidney sends a hormone signal to the bone marrow to make more red blood scells. The number of red blood cells increases, so more oxygen is carried in the blood
What is negative feedback?
A tomato plant grows in the direction of a source of light.
What is response to stimuli?
Water, because of its polarity, attracts to each other through this type of bond.
What is hydrogen bonds?
This macromolecule processes information that determines traits.
What is nucleic acids?
In enzymatic reactions, the substrate(s) binds to this location on the enzyme.
What is active site?
In childbirth, stretching of the uterus triggers secretion of a hormone, oxytocin, which stimulates uterine contractions and speeds up labor.
What is positive feedback?
The retinal tissue in the back of the eye is responsible for sensing light and transmitting that sensory information to the brain. The tissue is composed of many cell types, including several types of light‐sensitive photoreceptor cells, and several types of nerve cells.
What is organization? (or order; made up of cells)
The name for the substances in bodily fluids that absorbs increases in hydrogen and hydroxide ions.
What is buffers?
This is the name for a molecule that has a large number of repeating similar units bonded together.
What is polymer?
Enzymes catalyze chemical reactions by lowering this part of the reaction.
What is activation energy?
The term is used to describe all of the steps of a feedback mechanism.
What is feedback loop?
