Ecology and Population Dynamics
Which organisms have the most available energy in a food/energy pyramid?
Producers
The island where Darwin conducted most of his research
What are the Galapagos Islands
The chromosome that males pass to their sons
What is the Y chromosome
The gray wolf hunts and consumes cattle from a local farm.
What is parasitism?
The reactants of photosynthesis
Water, Carbon Dioxide, (sunlight energy)
Predation is an example of a density independent factor. True or False
False
The survival of those organisms best adapted to their environment.
What is Natural Selection
The genotype of an organism with two identical alleles for a particular trait?
What is homozygous?
Both organisms benefit from this type of symbiotic relationship.
Mutualism
The products of photosynthesis
Oxygen, glucose (sugars)
How much energy is passed on from one trophic level to the next?
10%
The legs of crocodiles and cats have similar bone structures and develop in a similar way which indicates a common ancestor. What are these considered?
Homologous Structures
The percent chance that the biological child of two heterozygous individuals with albinism, an autosomal recessive contition, will have albinism?
What is 25%
The tapeworm lives in the intestines where it lives and grows. The tapeworm robs nutrients from the organism or host.
What is Parasitism
The organelle where photosynthesis takes place
The chloroplast
Which organisms would contain the greatest amount of available energy?
The Sun, Coyotes. Rabbits or Grasses
What are Grasses
A change in the frequency of a gene in the population due to random chance is known as
What is genetic drift?
If a person with Brown hair has a heterozygous genotype, then their genotype is:
Bb
The remora fish swims along side the shark. The remora feeds off of leftover food that the shark is consuming. The shark does not eat the remora and is unaffected by its presence.
What is Commensalism
In what organelle does cellular respiration take place?
The Mitochondria
If the producers contain 10,000 Kcal, then how much energy will the secondary consumers contain?
100 kcal
Which cannot be used as evidence for evolution:
punctuated sedimentation.
similarities and differences in protein and DNA sequences between organisms.
the fossil record.
homologous structures.
What is punctuated sedimentation
In guinea pigs short-haired coats (S) are the dominant trait over the recessive, long-haired coats (s). If a homozygous short-haired male is crossed with a long-haired female, what percentage of the offspring would be long-haired?
0 %
The species relationships where one species benefits and the other is harmed.
What are parasitism and predation (predator/prey)
This statement illustrates the Law of Conservation of Matter. True or False:
In photosynthesis, CO2 and water are transformed into glucose and oxygen. In respiration, glucose and oxygen are converted back into CO2 and water. The same number and type of atoms are involved in both processes however, illustrating the Law of Conservation of Matter.
True
