The Problem:
Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs. The specific bean on which each egg is laid determines the future success of the larva that develops from that egg. Choosing where to lay an egg is the most important decision a female bean beetle will make for her offspring, yet even within one bean species the seeds available may be very different in quality. Seeds vary in size (even if from the same plant), so the amount of

- The Problem: Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs. The specific bean on which each egg is laid determines the future success of the larva that develops from that egg. Choosing where to lay an egg is the most important decision a female bean beetle will make for her offspring, yet even within one bean species the seeds available may be very different in quality. Seeds vary in size (even if from the same plant), so the amount of resource available to larvae on different beans will not be the same. Seed mass may vary by as much as 50% among mung beans purchased in a local store, a species on which Callosobruchus develops normally and may complete its lifecycle. Given the problem described above, what do you predict if the null hypothesis is true? If beans of various size are tested, then there will be no difference in larval success on beans of different sizes.…The Problem: Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs.

Given the problem described above, what do you predict if the alternative hypothesis is true? If the mass of all the beans are the same, then the larvae will be successful. If the mass of the bean varies, then the…the graph is depicting the size of eggs and number of eggs for the mycalesis terminus butterfly. the right of the graph represents the mass of the eggs (solid blue) and the left side represents the number of eggs (striped blue) Describe one realistic difference between host plants that might be affecting the numbers and sizes of eggs that a female lays on these plants. Suppose the ability of a female to adjust her egg and clutch size is an adaptation in these butterflies. Based on the difference between host plants that you identified in Part C, describe and explain why that difference would impact how a female adjusts the size or number of eggs (choose only one of these). Your answer just needs to be possible, not necessarily true.Create three Venn Diagrams. For the first diagram, identify two or three similarities and differences between plant and animal reproduction; for the second, two or three similarities and differences between plant and animal development; and for the third, two or three similarities and differences between plant and animal nutrition. Make your diagram on a separate sheet of paper or at the back of this answer sheet
- Course: Botany In stable populations, ones that are neither increasing nor decreasing in abundance (e.g., there are a million trees now and there will be a million trees a thousand years from now), about how many of a plant’s seeds survive and grow to adulthood, being able to replace it when it dies? If during the plant’s lifetime it produces 100,000 seeds, how many do not survive, do not grow, and cannot replace it when it dies. (Hint: Do not think of humans, as we are an increasing population, not a stable one. Almost all our children survive, but that is not true of any other species.) Answer and explain briefly.Unripe fruits are hard and tart. Ripening is a process that sweetens and softens the fruit to make it more attractive to animals who will eat the fruit and disperse the seeds. A plant hormone, ethylene, leads to the ripening of many fruits. Once ethylene starts being pro- duced, it initiates a feedback loop that causes more ethylene to be produced, increasing the rate of ripening. Which of the following best identifies and describes the feedback loop initiated by the pro- duction of ethylene? A It is a positive feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. B с D It is a negative feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus. It is a negative feedback loop because the initiating stimulus causes a subsequent de- crease in the stimulus. It is a positive feedback loop because the initiating stimulus causes a subsequent in- crease in the stimulus.Some aggressive understory ant species patrol the foliage of the tropical forest shrub Psychotria limonensis, wild coffee (Fig.1). The ants chase insects and other animals away from the plant's flowers and fruits. Explain why this behavior may enhance the plant's reproductive success during some periods, but decrease the plant's reproductive success at other times. Figure 1. P. limonensis V
- REPRODUCTION PLANTS ANIMALS Can reproduce asexually? If Yes, write the different ways on how they reproduce asexually. Explain and give an exampleThe mandible lengths of the camellia weevil (used to break through the pericarp of the Japanese camellia fruit) vary in the northern and southern regions of the country where fruit sizes are also extremely different. Southern weevil populations have longer mouthparts but are not sufficient to bore into the thick pericarp of the fruits; In the north, the insect mouthparts may be shorter but the weevils are more successful in boring through the skin of the smaller fruits. This study depicts an example of ______ coevolution. A. escalatory B. diffuse C. antagonistic D. reciprocalSexual vs. Asexual Reproduction: Which statement below is not true about asexual reproduction in plants. Less energy needed for reproduction as it is strictly mitosis, no sexual organs or gametes need to be produced. O If the parent plant with it's genome did well in a location then a clone will do equally as well in the same location. Reproduction is seasonal and will only take place once a year. O Vegetative structures may be used to go through dormancy periods (bulbs, tubers,etc). X= A A AY9 Week9_ng....xlsx Week 9 Pre-lab.pdf 10.7591 A MacBook Air y of Lab 9 A....pdf
