AND WELL DETAILED VERIFIED ANSWERS|GRADED A+|NEWEST
Biology - ANSWER The study of life and the branch of science that studies living organ-
isms and the way organisms interact with their environments.
Characteristics of Life - ANSWER 1. Be made of materials organized in a hierarchical pat-
tern.
2. Use energy and raw materials to survive.
3. Sense and respond to changing environments and maintain internal stability, or homeo-
stasis.
4. Grow, Develop and reproduce.
5. Be part of a population that evolves.
Cell - ANSWER Is the smallest unit that displays all of the characteristics of a living organ-
ism.
Matter - ANSWER any substance that has mass and takes up space.
Biotic matter - ANSWER if it was ever alive at some point. ex. bacteria, cotton, Yogurt.
Abiotic matter - ANSWER if it is nonliving and never has been alive. ex. water, Glucose,
carbon dioxide, Cold Virus.
All of the following are part of the sutdy of biology EXCEPT:
a) Living Organisms
b) The interaction between living organisms and their environment
c) Earthquakes
1
,d) Life - ANSWER C. Earthquakes.
Atom - ANSWER Basic unit of matter.
Molecule - ANSWER a chemical structure consisting of at least two atoms held together
by a chemical bond.
Macromolecules - ANSWER are important molecules that are technically polymers.
Prokaryotes - ANSWER small and simple, they do not have andy clearly defined compart-
ments inside of them.
Eukaryotes - ANSWER include membrane-bound organelles: compartments inside the
cell that contain specific groups of macro-molecules and carry out specific cellular functions.
Tissues - ANSWER Are formed when similar cells work together to fulfill the same de-
tailed function
Organs - ANSWER Are collections of tissues that work together to carry out a common
general function.
Organ System - ANSWER group of organs that work together to perform a specific func-
tion
Organisms - ANSWER are individual living entities that survive and reproduce as a unit.
for example: each tree in a forest is usually an individual organism.
Population - ANSWER all the individuals of a species living within a specific area.
2
,Community - ANSWER all populations that interact with each other in positive and nega-
tive ways.
Ecosystem - ANSWER consists of all the living things in a particular area together with the
abiotic or nonliving, parts of that environment.
Biosphere - ANSWER a collection of all ecosystems on Earth.
What level of organization is found within all of the other levels? - ANSWER Population
If you eat a hamburger, you are mainly eating ground-up beef muscle. What levels of organi-
zation are certainly represented in this ground-up muscle? - ANSWER Organelle, Cell, Tis-
sue
The first level of organization that is defined as living is: - ANSWER Cell
Emergent Properties - ANSWER Characteristics of a system that are not present in any of
its component parts.
What is the first level of hierarchical organization that possesses the emergent property of
life? - ANSWER Cell
Homeostasis - ANSWER The ability or tendency of organisms and cells to maintain stable
internal conditions.
Humans maintain a blood pH between 7.35 and 7.45. In order to maintain homeostasis, how
will your body respond if your blood pH drops to 7.0? - ANSWER if your blood pH is 7.0,
your body will raise your pH.

, Energy - ANSWER The capacity to do work or to make a change in the location, tempera-
ture, or structure of matter.
Reproduction - ANSWER Occurs when and individual organism passes on its genetic infor-
mation to a newly independent organism, or offspring.
What is the best, most precise description of DNA's role in an organism? - ANSWER DNA
is an inherited molecule that provides recipes for proteins. These, in turn, determine cell
structure and function.
You started life as a single cell and took on your current form through a process of develop-
ment and growth. Why do cells in different parts of your body have different functions and
characteristics? - ANSWER Each type of cell uses its DNA differently. The DNA is similar,
but DNA reacts o conditions and makes different products in each kind of cell.
Evolution - ANSWER A scientific theory that explains how and why life changes over time.
Natural Selection - ANSWER A natural process that helps explain how groups of organ-
isms become well- suited, or adapted, to their surroundings.
Science - ANSWER is a process that helps us to understand ow the natural world works.
Biology - ANSWER deals with understanding living organisms.
scientific inquiry - ANSWER is an approach to asking and answering questions, and is the
best approach we have to understanding the natural world and predicting natural phenom-
ena.
pseudoscience - ANSWER is any claim that purports or pretends to be scientific in nature,
but does not actually have the characteristics of true scientific inquiry.
