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
What alternate hypothesis could be posed given the data described in The Problem?
Beetles are not selective in laying eggs on surfaces |
||
Bean quality is an important factor in future success of beetle larva. |
||
Bean size has nothing to do with larva success |
||
Larvae will not succeed on a species of bean with a large variation in mass |

- 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.…arrow_forwardThe Problem: Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs.

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).

- 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.arrow_forwardPrairie Crocus Usually, the first spring flower people notice in the southern Yukon is the prairie crocus. Statements Related to the Adaptations of the Prairie Crocus 1 The prairie crocus, like the sunflower, is a heliotrope. That means its flower turns through the day to follow the Sun. The petals act like a satellite dish to focus the light and warmth of the sun into the centre flower. Small insects such as ants crawl into the centre of the flower, where the temperature is significantly warmer, and move around pollinating the flower. 2 The fine hairs on its leaves reduce water loss by protecting the leaves from the wind. 3 The crocus blooms while the flower is still close to the ground and well-protected. 4 Unlike most plants, the stalk continues to grow even after the flower has been pollinated so that the seed pod forms as high as possible for better seed distribution. Identify the statement or statements that you would consider to be adaptations that allow the prairie crocus to…arrow_forwardIn the Kotukutuku plant, Fuchsia excortiata, why do pollinated flowers remain attached to the plant for several days after pollination occurs and nectar is no longer produced Size of flower and pollination Annual versus perennial reproduction Time and expense to grow the pollen tube outweighs the cost of maintaining the flower on the tree Size of flower and number of flowers on inflorescencearrow_forward

But if the nectaries are too short, hummingbirds can get their nectar without pollinating them because they don't reach in far enough to touch the pollen-carrying anthers, thus no reproduction for the flower. Flowers evolve with an intermediate length of nectaries. This is an example of what sort of selection? Group of answer choices Disruptive Stabilizing Directional Sexualarrow_forwardDirections: Plants have two life stages. The gametophyte life cycle, wherein a haploid spore is produced, and the sporophyte life cycle wherein there is union of the gametes. Below are different events in the development of flowering plants. Arrange them in the correct order. Place the number from 1 to 6 inside the box. The hypocotyl pushes to the soil along with the cotyledon(s). It starts as a seed which contain the miniature plant called embryo. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm Mature plant develops the gametes, releases the pollen and pollinates the flower. It is the process wherein seeds are transported, spread or moved away from the parent plant either by wind, water, animals or insect. The plant, given enough nutrients will develop in a mature stage.
