Protecting and preserving natural resources and the environment
What is conservation?
100
The organic circulation of carbon from the atmosphere into organisms and back again
What is the carbon cycle?
100
The process by which organisms with favorable traits are more likely to survive and reproduce, leading to evolutionary changes in a population over time.
What is natural selection?
100
The physical appearance of an organism is called its
What is Phenotype?

In pea plants, yellow seeds are dominant to green seeds. A heterozygous yellow-seeded pea plant (Yy) is crossed with a plant that has green seeds (yy). What percentage of the offspring will have green seeds?
What is 50 %
200
The largest or maximum number of individuals of a population that a environment can support.
What is carrying capacity?
200
An increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes)
What is global warming?
200
The formation of new and distinct species in the course of evolution.
The formation of new and distinct species in the course of evolution.
200
If two alleles are the same, they are said to be
What is homozygous?
200
In rabbits, black fur (B) is dominant to white fur (b). A purebred (homozygous) black-furred male is bred with a female that has the recessive white fur. What will be the percentage of the black fur rabbit?
What is 100%
300
Name 3 limiting factors for an ecosystem?
What is food, water, and shelter?
300
Where is carbon stored the most in the carbon cycle?
What is the ocean?
300
What are 3 pieces of evidence for natural selection?
Fossil records, anatomical similarities, DNA similarities, comparing embryos
300
What are the 3 different allele combinations that can be formed normally in gametes produced from this cell?
Homozygous recessive (pp)
Homozygous dominant (PP)
Heterozygous (Pp)
300
In fruit flies, long wings are dominant and vestigial wings are recessive. If a long-winged fruit fly that is heterozygous mates with a fruit fly that has vestigial wings, which percentage of their offspring will have vestigial wings?
What is 50%
400
The carrying capacity of this population is
What is point A?
400
An increase in average temperature suggests a decrease in snowy days for a region because increased temperatures will....
What is allow snow to melt more quickly?
400
Based on the data in the graphs, how does beak size compare between the birds before the drought and the ones that survived the drought?
The birds that survived the drought have, on average, larger beaks.
400
What is the formula to calculate the probability of a trait present in a Punnett square?
What is the allele type divided by the total alleles and multiply that by 100
400
Human blood types are genetically determined. A male and a female both have blood type AB. If they have a child, what is the probability that child will also have blood type AB?
What is 50 %
500
When did the wildebeest reach carrying capacity?
Late 1970s
500
If researchers were to increase carbon dioxide levels in a portion of the forest and compare differences with a portion receiving unaltered carbon dioxide levels, a likely result would be that higher levels of carbon dioxide would _________ the amount of above-ground plant biomass in that area.
What is increase?
500
What happens to the genetic variation of the beaks after the drought?
Genetic variation or variability decreased after the drought
500
