PLS HELP WILL GIVE YOU 100 POINTS AFTER
Hypothesis: (5 pts)
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
β If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
It will decrease over the span of five years.
β If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
It will decrease over the span of five years.
β If the amount of food available is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
It will increase over the span of five years.
Procedure: (6 pts)
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.
Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation. The control group is the group in the experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimental groups that do have factors applied to them.
β Test variable/s (independent variable/s):
β Outcome variable (dependent variable):
β Control group:
Data: (7 pts)
Record your data from each trial in the data chart below:
Type of Factor
Beginning Frog Count
Simulation 1 (Low)
Simulation 2 (High)
Predators (alligators)
Pollution
Food (mosquitoes)
Graphs (6 pts)
Use the graphs from the data chart in the virtual lab and analyze the data. Describe the trends present in the graphs.
β Predators (alligators):
β Pollution:
β Food (mosquitoes):
Conclusion: (12 pts)
Your conclusion will include a summary and an interpretation of the lab results. Please write in complete sentences.
1. Which limiting factor(s) in this lab simulation are biotic?
2. Which limiting factor(s) in this lab simulation are abiotic?
3. Which limiting factor impacted the cricket frog population the most? Use evidence to support your answer.
4. Which limiting factor impacted the cricket frog population the least? Use evidence to support your answer.
5. Mosquitoes can carry and transmit disease to animals and humans. Explain how the cricket frog plays an important role in limiting the spread of mosquito-borne illnesses like West Nile virus and malaria.
6. Predict the long-term effects of these limiting factors on the cricket frog population in the pond ecosystem.
Here is one way you can answer this question. Do this for all three limiting factors.
If ___ continues to (increase/decrease), then .

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sisterβs risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
