Only complex organisms reproduce _________ and only simple organisms reproduce ____________.
Sexual and asexual
What is a major disadvantage of asexual reproduction?
No genetic diversity, vulnerable to the environment.
is a method where a parent organism breaks into pieces and each piece becomes a new organism.
In scientific labs, _________ is conducted to produce identical individuals from a cell or cluster of cells of a multicellular organism.
cloning
Sperm joins with an egg is
Fertilization
Which form of asexual reproduction describes the process of a cell dividing to produce a copy?
Binary fission (Fission)
Which process produces clones of a parent organism?
Cloning
Daily Double
are cells capable of developing into a new organism, often produced by a single plant which can lead to many new individuals.
A trait that helps an organism survive and reproduce is called
adaptation
Which term refers to the process by which individuals that are better adapted to their environment are more likely to survive and reproduce?
natural selection
New organisms that come from one or more parent organisms are referred to as
offspring
How do spores differ from other forms of asexual reproduction?
Spores can develop into new individuals independently
A small portion of a population that is geographically isolated from the rest of the population runs the risk of decreased
genetic variation
Female reproductive cell is an
Egg
How does natural selection lead to evolution?
Helpful variations accumulate among surviving members of a species
Through the process of ________ , offspring are produced from a single parent
asexual reproduction
In which type of asexual reproduction does the offspring grow on the parent and break off when developed?
Budding
Darwin concluded that organisms on the Galapagos Islands did what?
had changed over time
Female organ that produces eggs is an
Ovary
__________________ is the time when a person reaches peak physical development
Adulthood
__________reproduction, offspring are produced from two parents.
Sexual
Why is vegetative reproduction advantageous for plants?
It allows rapid and direct reproduction without seeds
Daily Double
An organism with favorable genetic variation will tend to survive and breed successfully?
A species of finch has been studied on one of the geographically isolated Galapagos Islands for many years. Since the island is small, the lineage of the bird for several generations is known. This allows a family tree of each bird to be developed. Some family groups have survived and others have died out. The groups that survive probably have
inherited some advantageous variations
What are the Human Stages of Pregnancy Development
