- What is the difference between additive and compensatory morality? What is the difference between top-down and bottom-up regulation of population size? please answer bothThe following are the concept of operant conditioning: Three techniques to increase response in operant conditioning are: a) Positive reinforcement b) Negative reinforcement c) Shaping Two techniques decreasing response in operant conditioning are: a) Punishment b) Extinction Direction: Explain each terms and give atleast 2 examples. Make your answers unique and thoughtful.Suppose that in maroon-fronted parrots, the number of chicks born each year in a population is compared to the number of predators in the same area. Correlation coefficient = -0.1 Number of predators Describe the type and strength of the relationship between number of chicks and predators. positive, curvilinear, weakly correlated positive, linear, strongly correlated negative, linear, weakly correlated negative, curvilinear, strongly correlated negative, curvilinear, weakly correlated Number of parrot chicks
- While you are roller-blading around Lake Artemesia in Greenbelt, you notice a fascinating bark beetle on the trees. Glad for an excuse to catch your breath, you stop and observe that there are three different feeding behaviors in these beetles and you record the ratios of beetles with each of these behaviors. Being the biologist that you are, when you get home you dive into the literature and find the following genotypes are in the beetle population. BB (feeds under bark) 0.7 Bb (feeds on top of bark) 0.2 bb (feeds on leaves) 0.1 What are the allele frequencies and expected genotypic frequencies? Explain.Which form of conditioning is used most for behavior modification? Why does this form work better? Why would Classical Conditioning help someone in their daily life functioning? Which form of conditioning would you most likely see in a classroom setting? Create your own examples of each form of conditioning. Be sure to include the following information in your answer. In addressing classical conditioning: Identify UCS, UCR, NS, CS, and CR. Discuss any stimulus generalization that you observed. Discuss any extinction and spontaneous that occurred. In addressing operant conditioning: Identify negative and positive reinforcements and punishments. Label the schedule of reinforcement or punishment.Upon observing a golden eagle flying overhead, a prairie dog on "guard duty" gives a warning call to other members of the prairie dog community that are foraging. Which of the following statements best explains this situation? O The guard dog exhibits altruistic behavior that increases inclusive fitness. O The guard dog exhibits innate behavior that increases survivability. O The guard dog increases the relative fitness in the prairie dog population. O The guard dog has higher individual biological fitness than the total population.
- Using the following diagram, determine the value of the PA and P for this animal compared to the population. (You do not have to account for the mean as that is the line.) Ep = +5200 BV = +2300 GCV = -1500 Et= -1800 Phenotypic value (P-H) Producing ability (PA)Suppose that in maroon-fronted parrots, the number of chicks born each year in a population is compared to the number of predators in the same area. Correlation coefficient = -0.1 Number of predators From the correlation analysis, is there strong evidence that the number of predators affects the number of parrot chicks? Yes, because the number of chicks decreases as the number of predators increases. No, because the correlation coefficient is close to zero. Yes, because correlation analysis is used to determine the effect of one variable on another. No, because correlation analysis does not determine if there is a causal link between the two variables. Number of parrot chicksThere are a wide range of potential costs and benefits of living in a group. Sometimes these costs and benefits can create tradeoffs with respect to optimal group size. The following graphs show two such factors – risk of disease (in red) and risk of predation (in black). Researchers can use these relationships to predict optimal group size (yellow star). Which of the following graphs is most consistent with what you would expect for these costs and benefits of group living?
- Group size reflects a balance between costs and benefits for members. Based on the figure, which of the following statements is false? 1 3 4 6 7 8 Group size Individual net benefit (benefit – costs)The cleaner fish, Labroides dimidiatus, uses visual cues to identify between different individual members within social groups. Kohda and colleagues looked at aggressive fish behaviours (rushing, bumping and biting) with other fish and images of themselves with and without mirrors. First, the scientists carried out a "dear enemy experiment" to see whether a cleaner fish habituated to a neighbour. Attack frequency (/1 hr) 30- 25- 20- 15- 10- 5- Glass 0- Day 1 n = 8 8 3 Toward the first opponent 8 2 8 4 8 5 6 6 6 7 600 6 9 6 10 8 Toward the second opponentWhat is the difference between the exponential (J-shaped) and the logistic growth model (s-shaped)? Select all that apply 0 Small populations grow more slowly in the logistic model because it assumes that there are fewer individuals capable of producing offspring The logistic growth model reaches and inflection point because resources can become limiting in large populations The exponential growth model assumes that there are no limitations of resources on a population no matter how large it gets Carrying capacity is only a component in the exponential growth model, not in the logistic growth model if populations were a metaphor for money, and you wanted to maximize your return on investment, you would choose the logistic growth model
