Can you please help me answer just a couple questions

A species of flowering plant produces vibrant blue flowers. The flowers attract both pollinators that spread the plant's pollen and herbivores that feed on the plant. An adaptation occurred through several generations of plant species, and the plant is now known for its long, sharp thorns. Why might this adaptation have occurred?
to absorb more water and nutrients
to attract more pollinators
to discourage herbivores
to provide shade for the plant
A population of snails on an island is disrupt during a violent storm. Portions of the population are carried by the storm surge to two new islands, while a portion remains on the original island, creating three separate populations. Conditions on one of the new islands are exactly like conditions on the original island. However, snails that landed on the second new island encounter a varacious new predator. What is likely to happen to these three populations?
Speciation will occur at the same rate in all three snail populations
Speciation will occur at the same rate in the snails that landed on new islands but not in the original snail population.
Speciation will rapidly occur in one of the snail populations that landed on new islands but not in the other two snail populations
Speciation will occur in the original snail population but will not occur in the populations that landed on new islands

Because you've run the questions and answers together, your post is very difficult to read. This makes it much easier to understand.

1. A species of flowering plant produces vibrant blue flowers. The flowers attract both pollinators that spread the plant's pollen and herbivores that feed on the plant. An adaptation occurred through several generations of plant species, and the plant is now known for its long, sharp thorns.
Why might this adaptation have occurred?
a. to absorb more water and nutrients
b. to attract more pollinators
c. to discourage herbivores
d. to provide shade for the plant

Please copy the rest of the questions, along with numbering and lettering the answers. Put **** next to the answers that you think are right.

Then we may be able to check your answers.

^^^^ just fixed it thanks for the tip

The adaptation of the plant species with long, sharp thorns likely occurred to discourage herbivores from feeding on the plant.

As for the snail populations, it is likely that speciation will rapidly occur in one of the snail populations that landed on the second new island due to the presence of a new predator. Speciation may not occur at the same rate in the other two populations (original island and first new island) or may not occur at all in those populations.

For the first question, the most likely reason for the adaptation of long, sharp thorns in the flowering plant is to discourage herbivores. The presence of thorns helps deter herbivores from feeding on the plant, protecting it from damage. To determine the correct answer, you can analyze the information given - the species of flowering plant produces vibrant blue flowers that attract both pollinators and herbivores. The adaptation of long, sharp thorns would most likely serve as a defense mechanism against the herbivores, rather than attracting more pollinators or providing shade for the plant.

For the second question, speciation refers to the formation of new and distinct species. The snails that were carried to the two new islands encountered different conditions - one island had the same conditions as the original island, while the other island had a new predator. Speciation is the result of isolated populations undergoing genetic and environmental changes over time, leading to the development of new species. Based on this information, it is likely that speciation will occur at a rapid rate in one of the snail populations that landed on the island with the new predator. The presence of a new predator can drive selection pressures, favoring certain traits that help the snails survive and reproduce, ultimately leading to the formation of a new species. The other two snail populations may undergo some degree of genetic variation and adaptation, but they will not experience the same selective pressures as the population facing the new predator. Therefore, the correct answer is "Speciation will occur rapidly in one of the snail populations that landed on new islands but not in the other two snail populations."
