What is Biological diversity? |
Reflected in the variety of life on Earth |
|
|
What are the five characteristics all living things have in common? |
They... - are made of cells - need energy - grow and develop - reproduce - have adaptations which allow them to survive in their habitat |
|
|
What is population? |
Members of the same species live in the same area, at the same time, and use the same resources |
|
|
What is a community? |
Different populations live in the same area, at the same time, of an ecosystem |
|
|
What is a species? |
A group of individual organisms that have te same basic adaptations thus they are similar in appearance |
|
|
Greater biological diversity allows for great chance of.... |
Survival for a species |
|
|
How do you name an animal? |
The first word is the name of the genus, the second word is the name of the species |
|
|
What are the tree types of symbiotic relationships? |
Commensalism Mutualism Parasitism |
|
|
What is commensalism? |
One of the organisms benefits and the other is unaffected |
|
|
What is mutualism? |
Both organisms benefit from the relationship |
|
|
Parasitism? |
One organism benefits while the other is harmed |
|
|
What is interspecies competition?
|
Happens when two or more species need the same resource |
|
|
What is resource partitioning? |
Adaptation by competing species resulting in the subdivision of an area so these species can coexist with less competition |
|
|
What is niche? |
The role of an organism within a particular ecosystem; its place and function |
|
|
What is variability? |
The differences within any given species |
|
|
What is Discrete variation? |
Inherited characteristics that have a limited number of characteristics |
|
|
what is continuous variation? |
inherited characteristics that can have a range of possible forms |
|
|
What is asexual reproduction? |
No need of another parent - they do it by themselves |
|
|
What are the six principles of genetics? |
- Traits are passed on from one generation of species to the next - genes are the units of heredity that determines traits of living things - Living things that reproduce sexually will inherit genes in pairs, where one set is contributed by each parent - some genes are dominant while others are recessive - Dominant genes hide traits of recessive genes whenever the inherited pairs of genes is one dominant and one recessive -genes may display incomplete dominance where they are neither dominant nor recessive |
|
|
what is allele? |
variations of possible DNA sequences in genes |
|
|
What is Mitosis? |
One parent cell produces two identical daughter cells (with the same amount of DNA/chromosomes/genetic material as parent cell) |
|
|
What is Meiosis? |
One parent cell produces four gametes that contain only half of the parent cell's DNA/chromosomes/genetic material |
