Adaptations and classification
adaptations
Animals: adaptations help to compete for limited resources such as
food, space, a
mate
and
water
structural adaptions: the
shape
or
colour
of the organism or part of the organism
e.g.
teeth
or
beaks
Behavioural adaptions:
migration, basking
physiological adaptions: related to processes such as
reproduction
and
metabolism
extreme heat
physiological: vasodilation- blood vessels expand, closer to the skin
behavioural: sticking out tongue, licking arms
structural: large thin ears, kidneys( need little to nothing to drink), digging feet, thick fur
nocturnal- night is colder
endothermic: warm-blooded, humans,dogs,mammels
cold climates
physiological; blood vessels get smaller, bluish purple on skin
behavioural; shivering, hibernation,migration
structural: small tails, waterproof/thick fur, small ears, big feet, blubber
ectothermic; cold-blooded, reptiles, amphibians, fish
homeostasis: maintain a constant temperature
enzymes; only work within a specific temperature range
classifications
13 billion known species
classification identifies organisms and shows relations
Domain Eukarya: everything with a nucleus
three domains:
bacteria
Arkchea (extremophils)
Eukarya
kingdoms:
animals ( 1 million insects)
plants
fungi
protist
within invertebrates there are 34 types of phylum
within vertebrates there are only one type of phylum
we classify things by DNA, embryology, genetics, biochemistry, evolutionary history and physiology
major groups are: mammals, amphibians, fish, birds, reptiles, insects, invertebrates, vertebrates
variation can occur in species due to genes or environment
variation can be continuous or discontinuous
a group of similar individuals within species can reproduce to create fertile offspring
