if you guys could check my answers I would be really grateful
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 population**
Speciation will occur in the original snail population but will not occur in the populations that landed on new islands
first one: wouldn't thorns discourage herb eating animals?
second one: A varacious?? new predator? That is certainly a new predator. I bet you meant Voracious
I agree with your answer as it is the best answer. The question in my mind is the word "rapidly". Few things occur rapidaly in nature.
^^ yea, sorry that was a typo. Thank you for your help!!
To check your answers, let's break down the questions and provide explanations for each.
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 the plant species, and the plant is now known for its long, sharp thorns. Why might this adaptation have occurred?
The correct answer is: to discourage herbivores.
Explanation: The adaptation of long, sharp thorns is likely to have occurred to protect the plant from herbivores. By developing thorns, the plant becomes less appealing to herbivores and reduces the chances of being eaten. This adaptation allows the plant to survive and reproduce successfully.
2. A population of snails on an island is disrupted 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 voracious new predator. What is likely to happen to these three populations?
The correct answer is: Speciation will rapidly occur in one of the snail populations that landed on new islands, but not in the other two snail populations.
Explanation: Speciation refers to the formation of new species from existing ones. In this situation, the snail population that landed on the second new island and encountered a new predator will likely experience a strong selective pressure. The predator may preferentially consume certain snails, leading to changes in the snail population's gene pool over time. This can result in the rapid formation of a new snail species on the second new island. However, the populations on the original island and the first new island may remain unchanged or experience different evolutionary pressures, leading to different outcomes.
It is important to note that the exact rate and outcome of speciation can vary depending on various factors, environmental conditions, and genetic variations within the snail populations.
