Describe each level of biosphere beginning with an organism. -
correct answer- ...smallest to largest-Organism, Population,
Community, Ecosystem, Biome, Biosphere. ORGANISM-A single
living thing that has all of the characteristics of life. Ex. Dog
POPULATION-Many organisms of the same type (species) in the
same place at the same time. Ex. a herd of Caribou
COMMUNITY-All of the different living things (orgamisms) in the
same place at the same time. ECOSYSTEM-All of the living things
(biotic) and the non-living factors (abiotic) in the same place at
the same time. BIOME-A region of the earth's surface with a
specific climate where only certain types of plants and animals
live. Ex. Tundra BIOSPHERE-The part of the earth's surface where
living things can be found. Ex. Earth
Describe how a hydrogen bond differs from a covalent or ionic
bond. - correct answer- ...hydrogen bonds-bond in which
hydrogen atom is covalently linked to an electronegative atom
but still attracted to other electronegative atoms-
Ionic bond =
, the transfer of electrons from one element to another; a bond
between two oppositely charged elements
covalent bond-
Formed from non-metals only
Covalent bonds
Share electrons in pairs; 1 shared pair = single bond, 2 shared
pairs = double bond, & 3 shared pairs = triple bond
Covalent bonds
Held together by mutual attraction for electrons
Describe the 4 steps of the scientific method. Including:
inductive and deductive responding, experimental variable,
responding variable, control, and objective data versus
subjective. - correct answer- ...#1-State the Problem: Find
out what your problem is.
- Define the problem clearly as possible--#2-Gather Information
(using the 5 senses:
ex: Touch, Taste, Smell, Sight, Hearing.)-#3 Form a Hypothesis: A
prediction that can be tested. #4-Test The Hypothesis (Use
