Biodiversity
Members of these two kingdoms have prokaryotic cells
What is eubacteria and archaea
The combination of two alleles for a particular trait
What is genotype
The ultimate source of variation within a population
What is genetic mutation
The smallest blood vessels
What are capillaries
Plant vascular tissue that moves water
What is xylem
These types of organisms thrive in harsh environments
If an organism has 14 pairs of chromosomes in its muscle cells, you will find this many chromosomes in its sperm cells.
What is 14 (total)
The type of selection that has resulted in fancy, colourful males such as the peacock
What is sexual selection
The major function of the large intestine
What is water absorption
Attractive forces between two water molecules
What is cohesion
If an individual has blood type IAi they will have this phenotype
What is type A blood
When a population evolves into two different species while existing in the same geographic region
What is sympatric speciation
The top number in a blood pressure reading
Systolic pressure
The tendency of plant roots to grow downwards
What is positive gravitropism
These fungi live on plant roots - both the plant and fungi benefit from this symbiotic relationship.
In cats, short fur (F) and black fur (B) are dominant, while long fur (f)and white fur (b) are recessive. In the cross FFbb x FfBb this is the probability that the offspring will be white and have long fur.
What is 0%
Structures that have different functions but the same anatomical structure suggesting common ancestry between two species
What are homologous structures
A protein in red blood cells that binds to oxygen
What is hemoglobin
Plants with flowers and fruit
What are Angiosperms
These are the three types of biodiversity
What are structural, genetic and species diversity
These two events occur during meiosis and increase genetic variability, producing genetically unique reproductive cells.
What are Crossing Over and Independent Assortment
Directional selection
What is the loss of the intermediate phenotype
An important structure inside the digestive tract for sufficient nutrient absorption
What are the villi of the small intestine
The first land plants acquired this trait that allowed them to survive beyond the aquatic environment
What is the waxy cuticle
