Which form of reproduction, in animals, is the most common on Earth?
Asexual
Sexual
Fragmentation
Vegetative propogation
Multiple factors influence the reproductive success of an animal. Select all that apply.
genetics
weather conditions
availability of food
protection from predators
Which type of reproduction involves two parents?
Asexual
Sexual
Fragmentation
Budding
Which type of reproduction produces the greatest amount of genetic variation in offspring?
Sexual
Asexual
Binary fission
Budding
Asexual reproduction would be the most favorable if the population had an opportunity to grow quickly?
True
False
Which is a benefit of internal fertilization?
produce far more offspring
use less energy to produce offspring
less competition for mates
offspring are better protected during early development
In internal fertilization, fertilization occurs
inside of a protective capsule, like a cocoon.
inside the body.
outside the body.
by pollination
An example of an organism that exhibits external fertilization would be a(n)
elephant
parrot
frog
turtle
A benefit to external fertilization is that
more offspring can be produced at once.
fewer offspring are produced, minimizing competition between them.
less energy is spent by the parents trying to find a mate.
it is easier for eggs to be fertilized.
Which is an advantage of internal fertilization?
More energy is spent by the mother before the offspring are born.
The mother may be more vulnerable to predators during pregnancy.
Mates must be near by and competition may be high.
It increases the chances that eggs are fertilized by a specific male.
An example of a courtship behavior that can increase a male's reproductive success is
A male gorilla displays strength and vocalizations to females.
A group of birds flies to a new location with more food resources.
A chimpanzee learns to use a tool by watching another chimpanzee.
Male and female robins sit on their eggs to keep them warm until they hatch.
Which of these best describes animal behaviors that improve reproductive success?
They are only instinctive and genetic.
They are influenced by genes and experience.
They are beneficial for survival and reproduction.
They involve thinking, reasoning, and problem solving.
Which of the following does NOT describe a parenting behavior that increases reproductive success?
building a nest
feeding young regurgitated meat
staying nearby newly hatched offspring
genetic variation
Choose ALL of the environmental factors that may influence the growth of an organism.
Inherited traits
predators
food supply
weather
Beneficial environmental conditions that affect animal growth include all of the following except
abundant food and water supply
clean air
fair weather conditions
genetic variation
When an animal grows, its cells
multiply in number but do not change in size.
multiply in number and also get larger in size.
do no multiply in number but get larger in size.
grow in size but decrease in number.
Most animals that exhibit external fertilization
have few offspring but devote a lot of time and energy into ensuring their survival.
have few offspring and do no devote a lot of time and energy to their survival.
have many offspring and devote a lot of time and energy to their survival.
have many offspring and do not devote a lot of time and energy to their survival.
The biological process during which mature individuals produce offspring is called as _________
reproduction
growth
population
fertilization
Why is reproduction important?
Because reproduction will enables living things to create and continue their population.
Because reproduction can do a gen mutation to create a better generation for the species.
Because not all species of living things are able to do the reproduction process.
Because each species need to be a dominant species on Earth.
What would happen to a species if every member could not reproduce?
The species will become endanger and can be extinct.
The fertilization is not needed because they will do asexual reproduction.
The species will arise as a dominant population on Earth.
The organism will adapt and prevent early death cases.
Animals reproduce in two ways, which are ______ and _____.
sexual
asexual
fertilization
embryo
What is the definition of fertilization?
The process of the male's sperm cell unites with the female's egg cell.
An early stage of development of a multicellular organism.
The development of the embryo inside the body of the parent.
The breaking of an individual into parts from which separate individuals will grow.
Two types of fertilization are ______ and _______.
internal
external
sexual
asexual
Where do the sperm and egg meet in external fertilization?
inside the male's body
inside the female's body
outside the animal's body, generally in the water.
After fertilization takes place, the fertilized egg will develops into a/ an ______
embryo
zygote
fragment
fetus
THREE characteristics of external fertilization are ______ , _____ , and ______.
The female produces plenty of eggs.
Happens in mammals, birds and humans.
Happen in an aquatic environment.
The survival rate of the offspring is low.
The sperms are deposited inside the female's body.
Three characteristics of internal fertilization are ______ , _____ , and ______.
Most of fertilized eggs survive.
Happens in mammals, birds and humans.
Happen in an aquatic environment.
The survival rate of the offspring is low.
Occurs inside of an organism's body.
What is the definition of asexual reproduction in animals?
A method of producing offspring from a single animal without fertilization.
A process where the male's sperm meet and unite with the female's egg.
A process in which the embryo develops into a new organism.
A type of reproduction where the embryo grow inside an egg.
Two types of asexual reproduction in animals are ______ and _______.
fragmentation
budding
laying eggs
mating
The reproduction method where the breaking of an individual into parts from which separate individuals will grow called as _____
fragmentation
budding
fertilization
variation
A form of an asexual reproduction method where an outgrowth of a part of the body form new individuals is called as _____
fragmentation
budding
fertilization
variation
The starfish is an example of animals that can reproduce by ______
fragmentation
budding
pollination
variation
