Actions and reactions an animal possesses when it is born
Learned behavior
those that the animal learns by itself or from other animals (i.e. its parents)
intelligent behavior
those that are based on special abilities like reasoning, analyzing, problem solving, and understanding.
Migration
the long distance seasonal movement of animals from one area to another
albumen
the white part of an egg
yolk
the stored food that the unhatched chick will use to grow
egg
female gamete; usually larger than the male gamete and does NOT have the ability to move itself
fertilization
occurs when 2 haploid gametes unite and form a diploid cell
gestation
the time a baby animal is spent in the uterus
incubation
the maintaining of the conditions necessary to hatch an egg
umbilical cord
the structure through which the embryo's blood vessels pass to the placenta
spawning
the laying of eggs in water by aquatic animals
mammory glands
an organ that produces milk to nourish the young
placental animals
a mammal in which the developing young in the uterus exchange nutrients and waste with the mother through a placenta
Reflexes and Instincts
What are the 2 types of innate behavior?
Reflexes
A simple, immediate response to some change in the environment (dog panting and tail wagging)
instincts
A complex reaction that require longer time to complete (nest building by birds or web weaving by spiders)
External and Internal
What are the 2 types of fertilization?
External
When the sperm and egg unite outside the parents bodies
internal
when the sperm and egg unite inside the parents bodies
