Misc.
This type of bonding between water molecules explains why water has a high specific heat, strong cohesion, and the ability to dissolve many substances essential for life.
What is hydrogen bonding?
This square is a useful tool for solving genetics problems.
What is a Punnet Square?
In this type of symbiotic relationship, one species benefits while the other is neither helped nor harmed.
What is commensalism?
These two categories separate living components of an ecosystem, like plants and animals, from nonliving factors such as temperature, sunlight, and soil.
What are biotic and abiotic factors?
One of the possible “versions” of a gene.
What is an allele?
Species with this survivorship pattern produce many offspring, most of which die young, but those that survive early life tend to live much longer.
What is a Type III survivorship curve?
These organisms keep ecosystems running by breaking down dead plants and animals, recycling nutrients back into the soil so they can be used again.
What role do decomposers play?
Mendel’s law describing the fact that gametes end up with only a single copy of every gene.
What is the Law of Segregation?
In this form of mimicry, a harmless species gains protection by resembling a dangerous or unpalatable one.
What is Batesian mimicry?
the complement of "ATC."
What is TAG?
Because only about 10% of usable energy moves upward in a food chain while matter continues to cycle, this is why energy flows one way through an ecosystem but nutrients do not.
What is the loss of energy as heat at each trophic level?
The situation in which the heterozygote has a phenotype that is intermediate (between the two homozygotes).
What is incomplete dominance?
This ecological concept explains why a species often occupies a smaller portion of its possible habitat due to competition or other limiting factors.
What is the difference between a fundamental niche and a realized niche?
This pair of ecosystem productivity measures includes one that represents the total amount of chemical energy produced by photosynthesis, and another that subtracts the energy producers use for respiration to show the energy available to the rest of the food web.
What is the difference between gross primary productivity and net primary productivity?
The phenotypic ratio expected from an F1 X F1 dihybrid cross when the two genes are UNlinked.
What is a 9:3:3:1?
These two types of speciation are distinguished by geography: one occurs when populations are physically separated, and the other occurs within the same area without physical barriers.
What are allopatric and sympatric speciation?
