What are the seven characteristics of all living things? - (answer)They are:
1. Organized
2. Metabolize
3. Reproduce
4. Grow and develop
5. They have homeostasis
6. Respond to stimuli
7. Evolve
How are all living things organized? - (answer)Because they are all made up of the same basic structures.
I.e.:
Atoms make molecules, which make cells, which make tissues, which multiple together make organs,
which make organ systems, which make an Organism. Then those make populations, which make
communities, which make ecosystems, which make the biosphere.
How do organisms acquire and utilize materials and energy, i.e., metabolize? - (answer)Humans and
other creatures do by eating food, and plants do from sunlight and soil.
Define reproduction? - (answer)When cells come into being from pre-existing cells, which means that all
living things have parents. DNA enables living organisms to pass on hereditary info from parent to child.
Compare and contrast growth and development. - (answer)In humans, development includes all the
changes that occur from the time the egg is fertilized until death. Growth is an increase in size
(hypertrophy) and often an increase in the number of cells (hyperplasia) and is included in development.
The repair that takes place following an injury is also a part of development.
Define homeostasis and know how various organ systems contribute to homeostasis. -
(answer)Homeostasis is an internal environment for cells that usually varies only within certain limits.
The cardiovascular system and the nervous system work together to maintain a constant temperature;
the digestive system takes in nutrients; the respiratory system exchanges gases with the environment;

LATEST UPDATE!!!! ALREADY GRADED A+
the cardiovascular system distributes nutrients and oxygen to the cells and picks up their waste; the
urinary system excretes metabolic waste; the nervous and endocrine systems coordinate the functions of
all the other systems.
Define how animals respond to stimuli. - (answer)Living things respond to external stimuli, often by
moving toward or away from a stimulus. E.x., drawing your hand away from a hot burner, moving
towards food, a plant following the sun.
How is evolution responsible for both the unity and diversity of life? - (answer)Evolution is the process by
which a species changes over time. It explains the unity of all life since it all came from an original cell
and share seven characteristics, and the diversity because species adapt to their environments, which
makes them different depending on where they live.
What are the three domains of life? - (answer)Bacteria, Archaea, and Eukarya
Describe the domain Bacteria. - (answer)**Don't forget to put in the rest of the study guide for Chapter
1.
*PUT THE REST OF CHAPTER 1 STUDY GUIDE ON* - (answer)Okay
Define Matter - (answer)Anything that takes up space and has mass/weight (can exist as a solid, liquid,
or gas).
Describe an Element - (answer)The things that all matter is composed of; there are 92 natural elements
and each one has a unique name and symbol. The building blocks of matter that can not be taken apart
by ordinary chemical means.
Describe the organization of an atom including its subatomic particles. - (answer)Subatomic particles are
protons, neutrons, and electrons. Protons are positively charged, electrons are negatively charged, and
neutrons aren't charged at all (which is why they're *neutr*al). Protons and neutrons make up the
nucleus (center) of an atom while the electrons orbit around it. The atomic number is the number of
, BIO 132 Exam 1 Based on Study Guides with correct answers 100% 2026
LATEST UPDATE!!!! ALREADY GRADED A+
protons (and therefore electrons, since they're the same amount), and the atomic weight (the number
on the bottom of the symbol) is equal to the number of protons and neutrons.
The first ring orbiting around the nucleus can hold 2 electrons. The next ring can hold 8, and the next
one can hold 18(?). The outermost ring is called the valence shell, and it likes to be full in order for it to
be stable.
What are Isotopes? - (answer)Isotopes are atoms that have the same atomic number but different
amounts of neutrons (e.x. C12, C13, C14). Most of them are stable, but some emit radiation.
Describe atoms with low levels of radiation. - (answer)They are radioactive isotopes that behave in the
same way that their stable isotope does. Low radioactive isotopes are used in many medical treatments.
Describe atoms with High levels of radiation. - (answer)These radioactive isotopes can be harmful to
human health, although they are used for cancer therapy and sterilizing things. Accidents at nuclear
power plants, however, can have long-ranging effects.
Define Molecule - (answer)Molecules are any two+ atoms that are bound together.
Define Compound Molecule - (answer)A molecule made up of two or more different kinds of atoms.
What are the two types of bonds that occur between atoms? - (answer)Ionic and covalent
What is ionic bonding? - (answer)Ionic bonding is when an atom gives up electrons from its valence shell
in order to become stable, which is called cation. Then another atom receives those cast out electrons
into its valence shell and it becomes stable, which is called anion. These oppositely charged atoms are
attracted to each other and form an ionic bond.
What is a covalent bond? - (answer)A covalent bond is when two or more atoms are share electrons in
order to make them more stable, which binds them together.
