- The next five questions (questions 11-15) are related to each other. Read all of the scenarios very carefully and in order and select the correct answer. A population of 10,000 blue grasshoppers lives on an island. Most members of the population live among the grasses because they are not very good climbers. Some grasshoppers live in the trees because they are good climbers. One year, a short-legged mouse arrived at the island and ate all grasshoppers within its reach, thus totally wiping out the grasshoppers living in the grasses. Luckily, those grasshoppers that were good climbers were spared. This story is an example of Gene Flow Founder Effect C Natural Selection Genetic DriftQUESTION 18 Consider the following scenario to answer the next two questions. Data from a hypothetical cohort study examining the association between lack of seat belt use and fatal vehicle crashes is presented in the following 2x2 table. Seat Belt Use Fatal Crash 60 30 90 No Yes Total No Fatal Crash 175 450 625 Total 235 480 715 Using this information, calculate the attributable risk. Express your answer as a decimal, and round to the nearest hundredth.I am doing an ecology research paper on Brown Anole Lizard Distribution, to perform my experiment I will choose 4 spots in a park such as a lake, a shaded tree, a boardwalk, and a sidewalk. then to quantify my results I will go three times a day for five weeks and count how many lizards I see in each area. I need help thinking of a good research question? it does not have to be long.
- A population of 30 rabbits has been introduced into a new region. It is estimated that the maximum population the region can sustain is 400 rabbits. After 1 year, the population is estimated to be 90 rabbits. How many rabbits will there be after 3 years? In a city whose population is 100 000 an outbreak of flu occurs. When the city health department begins, its record keeping, there are 625 infected people. The number of infected people N is increasing at a rate proportional to the square root number of infected people at time t in weeks. One week later, there are 1600 infected people. Find the number of infected people two weeks after the record keeping begins.You are a mad scientist tasked with the evil job of designing a novel species. This species will be introduced to an ecosystem and must cause as much damage as possible. What abilities and characteristics will you give this species to make it successful? Be sure to explain why you choose each aspect. Explain your choice in 3–5 sentences. Please answer ASAPPlease help with these as they are part of 1 question and I am so confused. I really need help like never before and I will highly consider thumbs up but please help asap. 1- Competitive exclusion means that salamanders from these four samples must have lived in four different geographic regions. ( choose true or false) 2- Salamanders from Sample 1 probably prey on salamanders from Sample 4. ( choose true or false) 3- There could be two species of salamanders represented in these samples, and Sample 2 and Sample 3 are from populations where the ranges of the two species overlap. ( choose true or false) 4- These four samples of skulls are from four different species of salamanders and Samples 1, 2, and 3 were collected in the same region but Sample 4 was collected from a different region.

- Since 1972, Dr. Jim Estes had been studying a food chain of kelp -> urchins -> sea otters, and then in the early 1990s orcas began eating the sea otters. The data collected by Dr. Estes are shown. Panel A shows sea otter abundance around four different islands from 1972 to 1997. Panel B shows the amount of sea urchins (sea urchin biomass) in 1987 and 1997. Panel C shows the amount of kelp that sea urchins ate over a 24- hour period (grazing intensity) in 1991 and 1997. Panel D shows the number of kelp plants within a specific area (density of kelp) in 1987 and 1997. The thickness of the arrows illustrates the strength of the effect one species has on the species below it in the food web. Sea otter abundance -Amchitka L N. Adak I. Kagalaska i. L Riskal. Sea urchin biomass Grazing intensity Total kelp density 1972 1985 1989 1993 1997 Year In 1997, which species is the apex predator in the food chain? No. per 0.25 m % loss 24hr gms 0.25m Otter No. (% max. count)Choose all incorrect statement. In 2021, 23 species were declared extinct. Most of these have been presumed to be extinct for decades. Eight of the declared extinctions were bird species endemic to the Hawaiian Islands. One species declared extinct was the Molokai creeper (pictured). Main causes of their extinction include loss of suitable habitat, disease, and predation by introduced mongooses and rats. Avian malaria is transmitted between bird species in Hawaii by mosquitoes that were brought to the islands by ships many decades ago. Which of the following statements is NOT accurate? a.Avian malaria is a vector-borne disease; if it infects 90% of the birds regardless of bird population size, it is acting as a density-independent factor. b.Among vertebrates, bird population sizes have declined the most compared to any other vertebrate group. c.Eliminating invasive rats and mongooses from the Hawaiian Islands, like goats were eliminated from the Galapagos, could help prevent further…Plant species: French Rose Animal Species: Siberian Tiger Answer all of the questions correctly!
