This is the process by which plant lose water to the atmosphere
Transpiration
A genetic mutation causes a frog to have faster reflexes. After many generations, why do most of the frog population have the reflex mutation?
Frogs with the mutation are better able to survive and reproduce than frogs without the mutation.
What is the correct order in which the human body will process macromolecules for energy?
Carbohydrates, Lipids, Proteins
Normal hemoglobin:
T-G-A-G-G-T-C-T-C-C-T-C
Sickle-cell hemoglobin:
T-G-A-G-G-T-C-A-C-C-T-C
What type of mutation is depicted in this sequence?
Substitution
What genus does the bull shark (scientific name: Carcharhinus leucas) belong to?
Carcharhinus
What do scientists predict will happen to the earth if greenhouse gas emissions continue to increase?
The temperature of the earth will increase.
Natural selection is a common mechanism for proposing how evolution occurs. Which statements describe how natural selection works over time in a population within an ecosystem?
The number of individuals with the most favorable traits increases in the population.
Charlie collected pond water while he was hiking. He is going to take it to the lab to look at it under the microscope. What is the best way for Charlie to decide whether he is looking at a plant or animal cell?
Only the plant cells have cell walls and chloroplasts
In cats, the allele for short hair (H) is dominant to the allele for long hair (h). A heterozygous short-hair cat is crossed with a long-hair cat.
What percentage of the offspring is expected to be heterozygous for hair length?
50%
One type of organism has some photosynthetic members but is primarily unicellular. They do have a true nucleus and organelles. Into which kingdom does this organism most likely belong?
A cuckoo bird lays its eggs in a warbler bird's nest. Once hatched, the cuckoo chicks displace the warbler chicks, tricking the parent warbler into caring for the cuckoo bird's offspring over their own young.
What type of ecological interaction does the cuckoo have with the warbler?
What is parasitism
A type of evolution used to describe an event where a population decreases dramatically. One example involves the northern elephant seal. They have a reduced genetic variation due to a rapid decrease in population due to hunting by humans in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted. Which phrase best explains this change in gene frequency? LT2 DOK2
What is the bottleneck effect
how does the addition of a catalyst affect the rate of a chemical reaction?
It speeds up the chemical reaction by reducing the activation energy?
What is the flow of genetic information in cells? (Central Dogma)
DNA --> RNA --> Protein
These organisms are eukaryotic, nearly all are multicellular; they are non-photosynthetic. To which kingdom do they best fit?
Kingdom Fungi
If the producers have 50,000 energy units available, about how much of this energy is transferred to the secondary consumers?
500
Some organisms have features that have different functions, but similar structures. One example is the forelimb of humans, dogs, birds, and whales. What are these structures called
What are homologous structures
What is the main difference between prokaryotes and eukaryotes?
What is the purpose of RNA?
Converts genetic information contained within DNA to build proteins
Prokaryotic organisms make up the
What are Domains Bacteria and Archae
If the organisms in the food web were arranged in an energy pyramid, which type of organisms would have the least amount of energy?
The tertiary consumer
Read the description and choose the correct type of reproductive isolation that it describes.
The American toad (Anaxyrus americanus) and Fowler's toad (Bufo fowleri) live in the same area. However, the American toad mates in early summer while Fowler’s mates in late summer.
What is temporal Isolation
