When looking at your pictures in order, describe the changes to the area. What changes happened first? Why do you think that is?

answer: There are changes in the climate which result in the environment changing. I think that in the picture before the eruption you can tell when this is because it shows the most "natural" of them all, with snow in the beginning and then it melts into picture number 2 which is the one right after the eruption. it shows climate changing resulting in the mountain snow to melt faster and develop into something similar but different.

Explanation:

1.Look at the photo of the rattlesnake. Why do you think rattlesnakes might be in danger of being stepped on? Why do you think natural selection would favor a characteristic that makes it more likely for a rattlesnake to be stepped on accidentally?

2.hat were the forces in the rattlesnake's environment that favored rattles? What in the environment might have changed? How does this affect whether rattling is a favorable or unfavorable characteristic?

Answers

Answer:

1. The reason I think that the rattlesnake might be in danger of being stepped on is that it like every other snake has to slither on the ground in order to relocate its-self to another place. If the environment were to change then the snake could be in a lot more danger because if the environment were to change it could cause food shortages and it could cause habitat destruction. The reason why I think that natural selection would make it more likely to be stepped on is because of the rattlesnake's camouflage that can make it blend in with its surroundings. This what can make it be stepped on accidentally.

2. The forces that were in the rattlesnake's favor were that in its natural habitat it enables it to blend in with its natural surroundings. The thing in the environment that might have changed is food and if there was a natural disaster this could make that happen. The way that this can affect whether the rattlesnake is a favorable or unvaforable characteristic is by it if it wasn't then it wouldn't be able to survive in its habitat, but, This rattlesnake is favored by this characteristic because it's able to survive in this habitat.

This space station has plants growing inside it, and astronauts who eat the fruits and vegetables from those plants. Because it is in space, the station is sealed so no material can get in or out.

The space station is in Earth’s shadow, so no light is getting into it. The sensors in the space station show that carbon dioxide in the air is increasing.

What is happening to the energy storage molecules in the plants and humans in the space station? Explain your answer as completely as possible.

Answers

Growing plants in space is tough -- low gravity means water distribution is difficult to manage, the roots are often starved of oxygen, and stagnant air reduces evaporation and increases the leaf temperature

The energy storage is decreasing since there is no sun.
