The common cuckoo is a parasitic bird that lays its eggs in the nests of host birds. The cuckoo's ability to copy the marking patterns on host birds' eggs has evolved over time.
However, the egg patterns of host bird species have also evolved, making them harder to copy and easier for parents to recognize. When host birds do not recognize an egg in their nest, they push it out of the nest. When host birds fail to reject a cuckoo egg, they care for the extra egg, and when it hatches, the baby cuckoo pushes the host bird's eggs out of the nest. The table shows the rate at which three host species recognize their own eggs and the rate at which they reject cuckoo eggs.
First, use the drop-down menus to explain the data.
Based on the data, the __________has coevolved with cuckoos over the longest period of time. This is because it has a __________developed ability to produce recognizable eggs and the__________rejection rate of cuckoo eggs.
Next, use the drop-down menus to support an explanation about genetic change in cuckoo and host populations.
The coevolution of genetic traits that allow cuckoos to copy host eggs and their hosts to produce recognizable eggs is a result of __________ because the genes of successful birds are passed to offspring,__________ the frequency of the genes that cause those beneficial traits in these populations.

Ruby-throated hummingbirds are found throughout eastern North America. They are omnivores, feeding on nectar, pollen, tree sap, insects, and spiders. They get all the water they need from nectar. Most nests are in forested areas, citrus groves, marshes, and scrubland. The hummingbirds breed in the spring and the summer, and females raise one to three broods per breeding season. Most of the hummingbirds migrate to Mexico or Central America for the winter. Many fly nonstop for 20 hours to cross the Gulf of Mexico. However, increasing numbers of the hummingbirds have begun to winter north of the gulf. Researchers have documented that the hummingbirds’ winter range has expanded northward by about 300 kilometers in recent years.
Which explanation BEST predicts the ability of the hummingbirds to survive their first winter in this new environment? DOK 3

Question 22

Structural changes of hemoglobin affect its ability to carry oxygen, indicating that the shape of a protein is important to its function.
Bromothymol blue (BTB) is a pH indicator that is also used to detect carbon dioxide (CO2) in water. BTB is blue when the pH of water is basic, and CO2 is low. BTB is yellow when the pH of water is acidic and CO2 is high. BTB is green when the pH of water is neutral.
Students are planning an investigation in which they will place the aquatic plant elodea in a test tube that contains water with a neutral pH of 7 and BTB. They will place a snail in another test tube with neutral water and BTB. The students will then place both elodea and a snail in a third test tube with neutral water and BTB.
Observing color change once the test tubes have been placed under a growth light for several hours will allow the students to answer which TWO questions?DOK 3 ALD 3
Does elodea produce oxygen during photosynthesis?
Does photosynthesis performed by elodea remove CO2 from the water?
Do both elodea and snails require oxygen to survive?
Do snails use the CO2 produced by elodea to produce oxygen?
Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?
Do snails respire faster when placed in a tube with elodea?
The tRNA delivers amino acids to the ribosome so that they can be added to the developing peptide
The tRNA scans the developing peptide to make sure that the sequence of the amino acids match the mRNA.
Daughter cells are all haploid but are not genetically identical.
Homologous chromosomes exchange genetic material during meiosis.
Heritable mutations caused by environmental factors result in the loss of entire chromosomes.
Daughter cells have too much or too little genetic material.
Homologous chromosomes separate incorrectly, producing daughter cells with unequal amounts of genetic material.
Supporting Evidence for Claim 1
Supporting Evidence for Claim 2
The lack of genetic variability among clones puts the whole species at increased risk of extinction
through a catastrophic disease or pest.
The increasing number of homologous sets of chromosomes with each successive generation of clones will eventually result in widespread death of banana plants.
Species in temporate and polar latitudes are better adapted to extreme weather.
Temperate and polar latitudes have a large amount of water from snow melt.

Which statement below correctly explains the model to describe how mitosis maintains genetic continuity? DOK 1
Scientists studied a species of phytoplankton. These phytoplankton are primary producers and are an important part of marine food webs. As all organisms are regulated by their environment, so are the phytoplankton. The scientists looked at the relationship between the phytoplankton population and a virus population found in the same environment. They created three environments in a laboratory setting to collect data on the numbers of phytoplankton and viruses over a period of time and graphed the results once they were averaged, as shown below.
The scientists claimed that the growth and stability of the phytoplankton populations were affected by the viruses. Using the information given, which TWO arguments support this claim? DOK 3
The phytoplankton population decreased as the number of viruses increased because the cells of the phytoplankton were destroyed as the viruses used them to increase the number of viruses in the environment.
The phytoplankton population was affected by the viruses because the viruses were competitors for the food sources in the environment.
The phytoplankton population was affected by the increase in the number of viruses in the environment because the viruses used most of the carbon found in the environment.
As the phytoplankton population reached capacity, the number of viruses increased because the phytoplankton were the hosts to the viruses and replicated the viruses’ genome.
As the phytoplankton population increased, the number of viruses increased because the phytoplankton were consumed by the viruses.
The phytoplankton population was unable to absorb the light necessary for growth because the viruses covered the surface of the water.
