Explain in short plz. Asap. Thanks Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, and gene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive

Directions: Research on examples of parasitic plants and predator plants. Give an example for each. What structural adaptations are present in these plants that allow them to acquire nutrition through parasitism and predation? Tabulate answers by using three columns with the following criteria: Type of Adaptation (parasitism or predation), Example Plant, and Structural Adaptation. Type of Adaptation Example Plant Structural Adaptation Parasitism Predation
emphasized how plastic and adaptable plants are in their environment. Write an essay touching on this concept. The first paragraph should be broad and discuss why plants must be more adaptable to their environment compared to other organisms, such as animals. Discuss if adaptation is or is not genetically determined and/or heritable. The second paragraph should provide a specific examples of how plants have adapted to stress. This portion needs to be in depth, and discuss both an abiotic and biotic stress.

Researchers performed an experiment on young individuals of two species of savannah tree (Figure 21.18). They determined the temperature to which each tree was exposed at different height as well as the diameter of the tree, which they used as an index of resistance to fire, as larger diameters = thicker bark and greater resistance to fire. What do the data suggest with regards to adaptation to frequent fire? ordeal tree 650- O O 8EDOD COO O D 450- O OO 0 250 O O 50+ 20 40 60 80 diameter (mm) monkey bread tree 650- BI 450- O O 250- 50+ 20 40 60 80 diameter (mm) Figure 21.18 Stems that survived (open squares) or died (black circles) after exposure to a particular temperature for both the ordeal tree (A) and the monkey bread tree (B).

Chemical Defenses: What is the benefit of having an inducible chemical defense, as opposed to a constitutive chemical defense? (an inducible defense is when the chemical is produced when herbivory is taking place as opposed to a constitutive defense where the chemical is always present) Inducible chemical defense best deters herbivory. With inducible defense predation will take place before a defense compound is produced which means there is damage to the plant before a defense is employed. With inducible defense herbivores are deterred even if no defense compound is produced. With inducible defenses energy is conserved by only producing secondary compounds when needed instead of continually. b 9 A....pdf XE A Week 9 Pre-lab.pdf A 10.7591 978150 A AY9_Week9_ng....xlsx

Carnivorous plants: CARNIVOROUS PLANTS Carnivorous plants attract insects promising a reward of food. This is an example of deception in communication. This only works because carnivorous plants are rare and commonly this attraction to food is rewarded by most flowering plants. Identify a cost to an insect species if they evolved a behavioral avoidance of carnivorous plant characteristics? The cost to insects would be they would overpopulate the niche and go extinct. If the insects evolved to avoid a potential food source they would reduce their fitness. O If the insects did not go to the carnivorous plants, they would die out. O There is no cost to insects if they evolve to avoid carnivorous plant characteristics. Week 9 Pre-lab.pdf A AY9 Week9_ng....xlsx A MacBook Air Copy of Lab 9 A....pdf 10.7591 97815
. According to the video and the background information, what are the effects (direct and indirect) that elephants have on acacias? (Select all that apply.) Elephants can feed on and destroy individual acacia trees not protected by ants. Browsing by elephants induces the acacias to provide food and shelter to the ants. Loss of browsing by elephants eventually leads to the decrease of ant colonization of acacias. Reduced nutritional and physical support of ants by acacias due to loss of browsing by elephants allows other ant species and stem-boring beetles to inhabit the trees. video link : https://www.youtube.com/watch?v=s3blzcbll7Q&t=293s
