Instructions: In this lab, you will investigate how limiting factors affect a population of cricket frogs in the Florida Everglades. Your scientific inquiry will focus on three limiting factors: food, predators, and pollution. Complete the following lab report to record your observations as you move through the simulation. You will submit your completed lab report for grading. Name and Title:
Include your name, instructor's name, date, and name of lab.

Objective(s):
In your own words, what was the purpose of this lab?

Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.

If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.

If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.

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.

Procedure:
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.

Test variable (independent variable):

Outcome variable (dependent variable):

Control group:

Data:
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
Use the graphs you printed from the data chart in the virtual lab and analyze the data. Make a note of any trends that you discover.

Predators (alligators):
Pollution:
Food (mosquitoes):

Conclusion:
Your conclusion will include a summary and an interpretation of the lab results. Please write in complete sentences.

Which limiting factor(s) in this lab simulation are biotic?
Which limiting factor(s) in this lab simulation are abiotic?
Which limiting factor impacted the cricket frog population the most? Use evidence to support your answer.
Which limiting factor impacted the cricket frog population the least? Use evidence to support your answer.
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.
Predict the long-term effects of these limiting factors on the cricket frog population in the pond ecosystem.
(I JUST NEED THE CONTROL GROUP AND CHART DONE. THE OTHER QUESTIONS ARE THERE SO YOU CAN UNDERSTAND WHAT THE ASSIGNMENT IS ABOUT. I WILL GIVE BRAINLIEST TO BEST ANSWER)

Answer from: Quest

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

Answer from: Quest

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

Answer from: Quest

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix. the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.

Can bacteria reproduce in a way such that when you start out with two bacteria, you get five bacteria? why or why not? * a. yes, because bacteria reproduce sexually, and can produce any number of offspring, just as humans do. b. no, because bacteria grow at an exponential rate. c. no, because when bacteria reproduce, they split into two parts, and two bacteria splitting would result in four bacteria.

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
