A group of researchers has made the claim that one particular butterfly species is the sole pollinator of a tree species and that consequently, the decline of the butterfly population will endanger the survival of the tree species. Data were collected and are summarized below. Which of the following data could best be used to either justify or refute the claim the researchers have made about the interdependence of the butterfly species and the trees? Tree flower size Number of butterfly visits per flower per day Nectar energy per pollination visit (joules) Fruits per flower
Small 1 10 0.88
Medium 9 12 0.79
Large 55 13 0.85

a. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.
b. The data collected for large flowers are most useful in justifying the claim, because they show that a large number of butterflies visit flowers of this tree species, obtain energy from nectar, and cause fruit production.
c. The data comparing the number of butterfly visits with the size of the tree flowers are most useful in refuting the claim, because they show that the butterfly does not visit all types of tree flowers.
d. The data showing the nectar energy available for all sizes of flowers are most useful in justifying the claim, because they show that butterflies benefit from the relationship with the tree by obtaining energy from tree nectar.

The correct answer is - A. The data comparing the fruits produced per flower with the number of butterfly visits are most useful in refuting the claim, because they show that the tree produces fruit even if the butterfly does not visit the flowers.

Explanation:

In this experiment, the table shows that specific butterflies did not go to small flower trees or go once a day where is in medium and large flower trees respectively they visit more than small flowers.

Even after not visiting small flower trees the nectar energy and the fruit production is almost similar to the other two trees. This case can occur only in one case if there are one or more pollinators present in this scenario other than this type of specific butterflies.

Thus, the correct answer is - option A.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
