Animal Behavior and Reproduction
Terms in this set (43)
the ability to communicate with symbols
example: dog panting
may attract mates; are very specific; are similar to hormones
when an animal can do something in less time because they have had time to learn from their trial and error
structure that a zygote of a live-bearing animal develops in
those that reproduce by external fertilization
Which types of animals generally produce the most gametes?
work outside the body
work inside the body
actions and reactions that are developed by observation and training (by itself, its parents, or other influences)
migration and other instinctive behaviors that are God-given behaviors
the more developed the young animal will be.
Usually, the longer the pregnancy...
uniting of gametes outside the parents' bodies
animals that lay shelled eggs and animals that give birth to live young
the time when an organism is developing inside the mother
actions and reactions that an animal possesses when it is born
a complex, inborn reaction
characterized by reasoning, understanding, and analyzing
an action that requires training
an instinct connected with reproduction
long-distance, seasonal movements
a chemical message to others of the same species
an inborn, immediate reaction to some change in the environment
when a sperm and egg unite
transfers or receives chromosomes
having only one of each type of chromosome
where eggs are formed
where sperm are formed
a cell that results when sperm and egg unite
example: peacock and goose
animals demonstrating instincts; animals demonstrating innate behavior
animal demonstrating a mating ritual
animal demonstrating a learned behavior
animal demonstrating intelligence
example: bird, turtle, elephant
animals that reproduce by internal fertilization
animal that produces the most eggs
animal that has a placenta
example: fish, turtle
animals provide no care for their offspring
animal with a long pregnancy
Innate - actions and reactions that God has given an animal when it is born (mating rituals, migration). Learned - developed by observation and training (dog that shakes hands, parrot that talks). Intelligent - based on abilities such as reasoning, analyzing, understanding, using tools, and communicating with symbols (dolphin communication, chimpanzees using tools)
Describe the three types of animal behavior and give an example of each.
Internal fertilization and external fertilization are both methods of sexual reproduction, and both occur in animals. Both use gametes produced by meiosis, and both involve the uniting of a sperm and an egg. In external fertilization the sperm and the egg unite outside the parents' bodies, but internal fertilization they unite inside the mother's body. External fertilization usually occurs in water, but internal fertilization does not. Animals that use external fertilization usually produce many more gametes than those that use internal fertilization.
In what two ways are internal and external fertilization similar? In what ways are they different? Give at least two similarities and two differences.
The great diversity of organisms God has created reveals His wisdom and power. He gave each organism just what it needs to survive in the environment He created it for.
How do the different types of animal behaviors and the different methods of animal reproduction show God's wisdom and lovingkindness toward His creation?
