The carrying capacity of the population is 2,000.
The first two questions are worth 10 points each.
The first two questions are worth 4 points each and the remaining four are worth 3 points.
For all your answers, use complete sentences.
When questions have more than one part, you should separate your answers to each part and use the letter for that part.
diagrams can be used to supplement your answers, but a diagram alone is not adequate.
Dissolved oxygen is measured from water samples collected at various depths in a freshwater lake.
The temperatures of samples are the same.
The graph shows the early growth of a population, labeled I, with two possible outcomes, labeled II and III.
The structure of a molecule is described by how it interacts with each other and with the environment.
Ceviche is not cooked with heat.
It is prepared by soaking raw fish in a strong acid solution made from limes or other juices.
A town in southern England had a form of deafness that was a form of deafness that was a form of deafness that was a form of deafness that was a form of deafness that was a form of deafness that was a form of deafness that was a form of deafness that was a form of deafness Several families from the town migrated to North America in the 1600s and settled on Martha's Vineyard.
The deafness of the descendants of the original families was high compared to other populations in the United States.
The population on Martha's Vineyard did not interact with the mainland during this time.
The families lived on the island.
Many new families arrived on the island in the early 1900s, while some families moved away.
By 1950, few people with deafness remained.
Plants and animals can respond to changes in the environment by using a variety of mechanisms.
There are many groups of organisms.
A portion of a DNA molecule is shown next to its normal type.
For reference, the genetic code is shown below.
The stomata are open during the day and closed at night.
It makes sense that the stomata must be open to allow CO2 to diffuse into the leaf.
The graph shows that the stomata are open for a longer period of time when CO2 concentrations are low.
CO2 isn't needed since photosynthesis doesn't happen at night.
The solution in the beaker turned blue because the IKI diffused through the bag and into the solution in the beaker.
The contents of the bag did not turn blue, so you know that the beaker did not get into the bag.
The bag is not impermeable to starch.
No conclusion can be drawn about the bag's permeability toglucose since no test was reported.
The signaling molecule is a small molecule thatbinds to a larger molecule.
There is a change in the shape of the receptor protein when the signaling molecule is binding to it.
You don't need to know that the signaling molecule causes twoRTKs to form a pair.
The next step is autophosphorylation, which allows the subsequentphosphorylation of relay proteins.
In turn, the phosphorylates relay proteins can be achieved by the activation of this receptor protein.
The GDP is exchanged for a GTP on a nearby GProtein, which is the RasProtein.
In a signaling cascade, multiple copies of the second protein kinase can be activated.
Multiple copies of the third are able to be activated by each copy of the second.
Each step of the cascade magnifies the response because each function is repeated until it is dephosphorylated.
A signaling cascade is intended to elicit a cellular response.
The activation of a second messenger or the inhibition of transcription factors are some of the cellular responses.
The signaling cascade that is shown in the figure is activated by the nucleus.
The cellular response is stimulated by the figure since it designates a signaling cascade.
Cell division can be initiated with the help of transcription factors.
The products of transcription are the messenger RNAs that are translated.
The figure shows a signaling cascade of products that stimulates cell division.
There would be a constant supply of mitogens, which would result in growth and cell division.
The defining characteristics of cancer are uncontrolled cell growth and division.
The reverse transcriptase is found in the retroviruses'RNA genome.
In the figure, reverse transcriptase makes a DNA complement of the viral RNA molecule.
In the figure, reverse transcriptase makes a second DNA molecule to complete a viral double-stranded DNA molecule.
The genes of the host are transcribed by the same way that the viral genes are.
The assembly of an HIV virus requires two copies of the viral RNA with the reverse transcriptase enzyme.
Some of the genes that are translated to produce the proteins end up in the reticulum, where they are modified into glycoproteins.
The virus leaves the cell and the glycoproteins are merged with it.
There are viral genes in the dsDNA.
When the dsDNA enters the nucleus, it gets transcribed into the host's genes.
The transcript of a viruses is copied.
The ability to repair copying errors is not available.
The genes of the viruses are different than the genes of the humans.
The outgroup species is the most primitive of the taxa being studied.
The outgroup doesn't have any of the recorded traits, so it branches from the tree first.
Both species I and II have trait X and Y, while species III only has trait X.
The species I and II are descendants of a common ancestor.
There are two ways to represent this tree.
The most closely related species are species I and II.
