On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection. It is believed that all of these species had one common ancestor and, over time, evolved into different species. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters. The finches varied mainly in the size and shape of their beaks. What statement BEST describes the speciation of the different finch species?

A The species all live on different islands.


B The different species no longer interbreed.

C The species eat different foods.


D The species no longer share any similar traits.

Answers

Answer 1

Answer: C) The species eat different foods.

Explanation: The passage mentions that the finches varied mainly in the size and shape of their beaks, which is directly related to their diet. The different species of finches have adapted to different food sources available on the Galapagos Islands. For example, some species eat seeds from the ground, others eat seeds from cactuses, and some eat insects from trees. These variations in diet and feeding habits have led to the evolution of different finch species.

Answer 2
C because the passage is talking about their diet!

Data was collected concerning Galapagos bird beak size over time. There are 13 types of Galapagos finches, and they are also known as Darwin's Finches. These finches share the same habits and characteristics except for one; they all have different beaks. The differences in their beaks might be the most important aspect of their survival because beak size determines the type of seed able to be eaten. Only the birds with the largest of beaks are able to eat the toughest, biggest, and spine covered seeds. Based on the data given, choose the BEST conclusion.

how might staying fit help cope with stress

Answers

Exercise makes us happy: When we exercise, our body releases chemicals called endorphins, which can make us feel happy and less stressed. So, even if we feel down or upset, going for a run or doing some jumping jacks can help us feel better!

Exercise helps us sleep better: When we're stressed, it can be hard to fall asleep at night. But when we exercise, we can tire our bodies out, making it easier for us to fall asleep and stay asleep. Getting enough sleep is important because it helps our bodies and brains rest and recover, which can help us feel less stressed.

Exercise gives us a break: Sometimes when we're feeling stressed, it can feel like we're stuck in a never-ending cycle of worry or anxiety. But when we take a break to exercise, we can give our minds a chance to rest and focus on something else. It's like hitting the reset button on our stress!

Answer:

Physical activity helps to cope with stress by releasing happy chemicals in the brain
