Freshwater Fish: About 200
Endemic Species - CORRECT ANSWER✅✅✅Live in only one or a very SMALL number

Cosmopolatin Species - CORRECT ANSWER✅✅✅Species that live in most regions of the
world
92% species of LAND birds are .. &
26% species of MARINE birds .. - CORRECT ANSWER✅✅✅Endemic
Biological adaptation - CORRECT ANSWER✅✅✅an anatomical structure, physiological
process or behavioural trait of an organism ... That increases its expected long term reproductive
success.
Describe The Blue Footed Booby - CORRECT ANSWER✅✅✅-ADAPTED FOR DIVING
INTO WATER
-Steamlined shape, large tail, & nostrils that are closed: useful for diving.
-Large, webbed feet help propel the bird through water in high speeds.
-Specialized salt-secreting glands manage salt intake while at sea.
-Uropygial Gland ( for waterproofing )
Describe Greater Frigates - CORRECT ANSWER✅✅✅- ADAPTED FOR ARIEL LIFE
,-Highest ratio of wing span/weight
-Tiny unwebbed feet
-Vestigial uropygial gland (waterproofing unnecessary)
Give 3 different Environments. - CORRECT ANSWER✅✅✅Marine, Freshwater,
Terrestrial (arctic, rainforest)
Biology
-Greek & Logos - CORRECT ANSWER✅✅✅-The study of life/Living things.
BIO= life
LOGOS= Knowledge
Evolution - CORRECT ANSWER✅✅✅Living things change gradually from one form into
another over the course of time.
Why are there very few museums of biology? - CORRECT ANSWER✅✅✅They are usually
called museums of natural history.
Zoology - CORRECT ANSWER✅✅✅Animals
Botany - CORRECT ANSWER✅✅✅Plants
who is considered the father of biology? and why? - CORRECT ANSWER✅✅✅Aristotle
-one of the first to classify the relationships of living things.
-1st person to apply empirical techniques & a rudimentary scientific method to the study of
living things (animals).
Empirical Method - CORRECT ANSWER✅✅✅Collection of data.
,Inductive Reasoning & example. - CORRECT ANSWER✅✅✅-general conclusions are
drawn from specific observations.
-A bee, wasp, & fire ant are all HYMENOPTERANS (have stingers)
- people assume that all hymenopterans have stingers BUT THEY DONT.
Deductive Reasoning - CORRECT ANSWER✅✅✅Specific observations are PREDICTED
from a general premise. (come up with idea, then start looking for observations)
Example of Deductive Reasoning. - CORRECT ANSWER✅✅✅-All wasps have stingers(as
figured our before)
-when given a picture of a bug that looks like a wasp, you think that it can sting you.
-However it might be a bee that looks likes a wasp.
where do polar bears & Penguins live? - CORRECT ANSWER✅✅✅Polar Bears: Arctic
Penguins: Antarctic (southern hemisphere)
Polar Bears are adapted to deal with: - CORRECT ANSWER✅✅✅-Cold temperatures
-Moving across snow, ice & open water.
-Hunt for prey (seals)
Adapation - CORRECT ANSWER✅✅✅Evolutionary process (takes time) whereby a
population becomes better suited to its habitat.
Polar Bear adaptations. - CORRECT ANSWER✅✅✅-THICK LAYER OF FUR
(insulation against cold, Camouflage)
-SMALL EARS
(reduce heat loss)
-FUR ON SOLES OF FEET
, (insulation, Better grip on ice)
-STRONG LEGS
(swimming, running, catch prey)
-LARGE FEET
(spread body mass on ice & snow)
-THICK LAYER OF BLUBBER(fat)
(insulation against cold, store energy)
Apex Predators - CORRECT ANSWER✅✅✅Top of the food chain (lack natural predators)
The scientific Method consists of: (4) - CORRECT ANSWER✅✅✅1. Producing hypothesis
2. Doing experiments to support hypothesis
3. Analyze data, without background of existing knowledge.
4. Draw conclusions that support or reject the hypothesis.
Structural - CORRECT ANSWER✅✅✅= anatomical or morphological (polar bears, blue-
footed booby, greater frigate)
Killer whale (general)
-habitat
-Diet - CORRECT ANSWER✅✅✅-Prefer cold waters, but can survive in warm tropical
waters
-Diverse diet
-Feed on almost every marine mammal species available
Killer whales in resident populations in Alaska & BC feed on... - CORRECT
ANSWER✅✅✅Fish & squid
