BIO 107 EXAM 1 QUESTIONS AND ANSWERS (100% PASS)

Describe what is meant by the term 'Biology' - ✔️✔️The scientific study of life

List and recognize examples of the characteristics displayed by living organisms - ✔️✔️1)
Energy processing; Humans ingest energy units and burn energy units.

2) Order; Flowers have petals on the outside of the center. Cells have membranes

3) Evolutionary adaptation; Seahorse adapts to be able to camouflage in its
environment

4) Growth and development; Oak tree starts from acorn, cells grow by division.

5) Regulation; Humans maintain homeostasis through sweating.

6) Reproduction

7) Response to the environment

Compare methods for categorizing living organisms according to the three Domains of
Life: Archaea, Bacteria, and Eukarya; Given a description of an organism, place it in its
appropriate domain - ✔️✔️Archaea and bacteria = prokaryotes; microscopic organisms
with relatively simple cells; no nucleus or membrane bound true organelles



Eukaryotes = organisms with more complex cells; protists; have nucleus and membrane
bound organelles; Kingdom Plantae; Kingdom Animalia; Kingdom Fungi

Describe the levels of biological organization from molecule to the biosphere - ✔️✔️atoms

molecules

organelles

cells

tissues

organs

organ systems

individuals of a species is called a population

community

- ALL living things in a geographic region that interact with each other

ecosystem

- living and NON living things included

Evolution - ✔️✔️applies to every single biological organism; occurs through the process
of natural selection; environment selects traits = adaptation



Darwins Theory of Evolution

Unity and Diversity - ✔️✔️birds have shared characteristics as well as evolved
characteristics;

phylogenic tree - common ancestors diverge from one another;

all forms of life are unified, share the 7 common properties of life, are made of cells, use
DNA as the genetic material

Flow of information - ✔️✔️how information is structured, stored, and passed;

* Organisms detect and respond to stimuli

* glucose enters blood stream after consuming food

* body needs to regulate blood glucose

* pancreatic cell releases insulin

* insulin binding stimulates body cells to take up glucose

* normal blood glucose level removes signal, insulin release stops

Structure and function - ✔️✔️how an organism works is based on structure;

each major group of organisms has evolved structures that make particular functions
possible;

red panda has thumb for grabbing trees?

Transfer and transformation of energy and matter - ✔️✔️energy/matter can move from
one form to another;

* matter = takes up space, has mass, made of elements and chemicals

* energy = has no mass

plants take in light energy and convert it into sugar using chloroplast;

all matter on this planet was here when the earth was formed, with the exception of
meteors that hit our planet

Interactions within & between systems - ✔️✔️systems can interact with one another;

organ systems interact with each other;

Emergent properties - ✔️✔️New properties that arise with each step upward in the
hierarchy of life, owing to the arrangement and interactions of parts as complexity
increases;

* new properties that emerge when moving up the hierarchy of organization due to the
interaction of component parts

* can be between a living and non living thing in an environment

Relate the connections between Charles Darwin and evolutionary theory - ✔️✔️"The
Origin of Species"

1) species living today arose from a succession of ancestors that were different from
them - "descent with modification"

2) natural selection - individual variation and overproduction offspring -> better traits are
more likely to survive, higher proportion of individuals will have the better trait
