- Age structure diagrams for two hypothetical human populations are shown below. Describe the growth rate of each population and discuss the current and future social and economic problems that each is likely to face.Based on the text for mosquitoes eating: 1. Identify abiotic factors that support the survival and reproduction of the mosquitoes. 2. Identify biotic factors that support the survival and reproduction of the mosquitoes. 3. Predict what factors in the environment can be altered to decrease the survival and reproduction of the mosquities. PLEASE ANSWER BASED ON THE TEXT ONLYFor Meal Worm give the reader background on the relevant science like the species, life cycle, habitat/ niche of each stage, and metabolism. Data: • in 6 Celsius temperature from 10 meal worm none shedded and none died • In 26 Celsius temperature 2 meal worms out of 10 shedded and 1 died having only 9 alive Please please Site your sources for the information you found and Avoid saying: GROW, PROVE, IN THIS EXPERIMENT Common problems with poorly written lab reports. • Use the abstract to introduce the report instead of to summarize. • Refer to the specimen by common name instead of by scientific name. • Refer to errors that may have occurred without discussing the evidence that those errors actually did occur Can you please please answer I really need it please at least try to answer it's very important please thank you I would really appreciate it if you could please try to answer
- The figure below illustrates the thermal performance curve for the intrinsic rate of increase (r) of an Aphid insect. Imagine you are studying a population that was historically exposed to 25C during the breeding season, yet climate-change predictions suggest that the population will be exposed to an average of 32C by the end of the 21st century. Select the changes below that you predict could at least partially mediate the consequences of climate change for population growth. Hint: First think about how the climate change described will and will not challenge homeostasis. Next, recall some of our earlier modules that talked about how animals can alter behavior, physiology, etc to maintain homeostasis. Select the answers that could allow the animals to maintain homeostasis given the scenario. a) Do nothing (i.e. no changes) b) Evolve a larger body size with smaller surface-area to volume ratio c) Disperse to lower elevation habitats d) Disperse to higher elevation habitats…What is the flask’s carrying capacity for rotifers in the presence of water fleas? a. 0 b. 4,200 c. 3,000 d. 1,800For each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.
- The three types of curves are also described as: early loss, late loss, and constant loss. Propose an organism that would have a Type 2 curve. Defend your choice by describing this animal's life pattern using the data and growth curve as a guide. (If you are really stuck, use google to look up survivorship curves)Based on the text on roaches eating: 1. Identify abiotic factors that support the survival and reproduction of roaches and explain why they need this factors 2. Identify biotic factors that support the survival and reproduction of the roaches and explain why they need this factors 3. Predict what factors in the environment can be altered to decrease the survival and reproduction of roaches and why? PLEASE ANSWER ALL QUESTION BASED ON THE TEXThttps://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html Now you'll tie together what you've learned. Read over the information on what's happening with the study of lionfish (you can ignore the questions on this page). Answer the question here on Canvas. 18)Based on what you've learned about the invasive lionfish population in the Atlantic, and the various types of factors that may limit population growth, which ONE factor (intraspecific competition, interspecific predation, disease & parasites, social behavior) do you think would be the MOST limiting? Why?
- INTERPRET DATA Examine the top and middle graphs in Figure 54-5. Are these examples of exponential or logistic population growth? Where is K in each graph? (You may need to refer to Chapter 53 to answer these questions.) RESULTS AND CONCLUSION: The top and middle graphs show how each species of Paramecium flourishes when grown alone. The bottom graph shows how they grow together, in competition with each other. In a mixed culture, P. aurelia outcompetes P. caudatum, resulting in competitive exclusion. SOURCE: Adapted from G.F. Gause, The Struggle for Existence (Williams and Wilkins, Baltimore, 1934). Figure 54-5 G.F. Gauses classic experiment on interspecific competitionmanatees are shallow water herbivores that face increasing threats. Use your know knowledge of seawater properties to describes some of the reasons why manatee populations are in decline. How can we reverse this decline?
