- Species that have many offspring at one time are usually: a. r-selected b. K-selected c. both r- and K-selected d. not selectedWhich of the following statements most accurately describes the example of species interactions for ants, plants and aphids Question 2 options: The burdock plant is negatively affected by a heavy aphid investation, the ants are negatively affected by the aphids and aphids are positively affected by the ants. The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are not affected by the ants The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants. The burdock plant is not affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.
- 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.The following experiment is used for the following question. A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers, but caterpillars that hatch in summer feed on oak leaves and look like oak twigs. How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below. Temperature Springlike Springlike Summerlike Summerlike Day Length Springlike Summerlike springlike summerlike In each of the…Populations of organisms can be found as clumps, randomly dispersed, or uniformly dispersed. Classify each of the following populations by the way it is dispersed in its ecosystem. Dandelions that produce many seeds dispersed through wind energy Tree of heaven that can produce clones of itself via underground roots called suckers that spread out from the parent tree Honey bees that maintain one social hive Red squirrels defending their individual territories from other red squirrels in the ecosystem
- Figure 4. This map shows the range of five different bird species in North America based on data collected from 1980 to 1995. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. Bird W's only source of food is the nectar from the Purple Cactus. Therefore, the Purple Cactus must have a range no larger than Bird W's range. Question 11 options: True FalseWhich of the following situations could decrease the average fitness of a population? Question 9 options: Snakes in a small and isolated populations must breed with blood-relatives. A sudden forest fire kills 95% of a population of minks, leaving behind the remaining 5% to repopulate the area. Seeds dispersed by wind arrive on an island, germinate and begin breeding with the existing island population. Atlantic salmons adapted to live in captivity escape from a fish farm and breed with wild stocks. All are the listed situations could lead to a decrease in average fitnessWhich is an example of disruptive selection? Group of answer choices Drug resistance increases with each generation; the resistant bacteria survive, and the nonresistant bacteria get killed off. Swiss starlings usually lay four or five eggs, thereby increasing their chances of more offspring. Over time, Equus developed strength, intelligence, speed and durable grinding teeth. Panay island snails mainly have two different phenotypes, black and white shells.
- Which of these conditions should completely prevent the occurrence of natural selection in a population over time? Group of answer choices The population size is large All variation between individuals is due only to environmental factors The population lives in a habitat where there are no competing species present The environment is changing at a relatively slow rateI 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 testable hypothesis? This is often similar to your research question, however, it can be answered with the numbers you will collect. For example, a research question could be: Which is better, a park or a nature preserve? A testable hypothesis would be: Do parks or preserves have higher bird populations?Another way to say "Natural Selection" is: differential success in reproduction mutation selective breeding differential access to mating partners variation O preferential sex choices
