Characteristics of Life
The characteristic that means all living things are made up of these basic units.
What are cells?
The smallest level in the organization of living things listed in the study guide.
What is an atom?
This macromolecule provides an immediate source of energy for the human body.
What are carbohydrates?
The building blocks of proteins are these small molecules.
What are amino acids?
Different types of atoms are called these.
What are elements?
The characteristic that describes an organism detecting and reacting to a change in its internal or external environment.
What is response to stimuli?
The level of organization made of similar cells working together to perform a function.
What is tissue?
Glucose, starch, cellulose, and glycogen are examples of this macromolecule.
what is types of carbohydrates
Enzymes, hormones, antibodies, and receptor molecules are examples of this macromolecule.
What are proteins?
These are the connections between atoms that hold atoms together to form molecules.
What are bonds?
The characteristic that includes producing offspring and passing genetic material to the next generation.
What is reproduction?
The correct sequence from simplest to most complex is atom, molecule, organelle, cell, tissue, organ, organ system, and this.
What is an organism?
The building blocks of lipids are these two smaller molecules.
What are glycerol and fatty acids?
This macromolecule contains carbon, hydrogen, oxygen, nitrogen, and phosphorus and includes DNA, RNA, and ATP.
What are nucleic acids?
Carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus are examples of these.
What are elements?
When a person sweats because the body becomes too warm, this characteristic of life is being demonstrated.
What is maintaining homeostasis?
The heart, stomach, and lungs are examples of structures made of different tissues that work together for a specific function.
What are organs?
This macromolecule contains carbon, hydrogen, and oxygen but does not have a hydrogen-to-oxygen ratio of 2:1
What are lipids?
The building blocks of nucleic acids are these molecules.
What are nucleotides?
Carbohydrates, lipids, proteins, and nucleic acids are large molecules made from smaller molecules and are known by this term.
What are macromolecules?
A plant uses sunlight during photosynthesis, while an animal obtains energy from food. Both examples demonstrate this characteristic of life.
What is using energy?
A group of organs working together, such as the heart and blood vessels, represents this level of organization.
What is an organ system?
A person needs a long-term energy reserve, and the body stores energy in fats, oils, or waxes. These substances belong to this macromolecule group.
What are lipids?
A molecule helps repair body cells, another speeds up chemical reactions, and another helps defend the body. All are examples of this macromolecule.
What are proteins?
An atom joins with other atoms through these connections, forming a larger structure called a molecule.
What are bonds?
