The Two-Sided Attack on the Spiny Cactus The spiny cactus is a type of plant that lives in a desert environment. A population of spiny cacti shows variation in the number of spines on their outer surfaces. The graph below shows the distribution of the number of spines before the introduction of collared peccaries and parasitic wasps. Spiny Cactus Organism Collared peccary (musk hog) Number of Cacti Parasitic wasp 300 200 100 T Collared peccaries and parasitic wasps are two organisms that were introduced to the ecosystem in which the spiny cactus population lives. The chart describes the relationship between the spiny cacti and these two organisms. 70 1 1 80 90 100 110 120 130 Number of Spines Organisms Introduced into the Ecosystem Relationship with Spiny Cactus Plants They eat spiny cactus plants that have a small number of spines. They lay eggs at the base of cactus spines. When the eggs hatch, the emerging grubs dig into the interior of the cactus and eat the inner pulp of the…

Use the information to answer the following question. Some species of sea stars are able to reproduce both sexually and asexually. Increasing ocean temperatures have impacted the environment of sea stars around the world. Which argument provides the MOST LIKELY explanation for why populations that use sexual reproduction will demonstrate increased survival than those that use asexual reproduction? O A. The population that uses sexual reproduction will have less genetic diversity which will allow them to adapt to the new conditions more quickly. O B. The population that uses sexual reproduction will be able to reproduce at a faster rate and replace the individuals that do not survive new environmental conditions. O C. The population that uses sexual reproduction will reproduce at a slower rate allowing for them to identify and adapt to the new environmental conditions. O D. The population that uses sexual reproduction will have increased genetic diversity which will allow the population…

This example of the Bollworms is an example of evolution by natural selection. For this to be the result of evolution which of the following statements must be true? Worms can change and become resistant to the toxic pesticide during their lifetime. The pesticide causes the mutation that makes the worms resistant. The ability of worms to survive exposure to the toxic pesticide is due to a genetic difference. DELL F5 F6 F7 F11 PriScr F12 Insert F10 %24 5 T G M. Of Alt Ctrl
