1) Panspermia is a hypothesis that states that life on Earth may have been purposefully or accidentally seeded by life from other planets. Which piece of evidence below would support this theory? Select ALL that apply.
A) The presence of intense heat on other distant planets
B) The presence of carbon-based molecules on meteors that strike Earth's surface
The fact that extremophilic bacteria can grow in harsh conditions even on Earth
D) The fact that photosynthesis is driven by solar energy and there are more stars across the galaxy
E) The fact that some spores from fungi or endospores from bacteria can lay formant for long periods of time
One of the events that could give credence to the panspermia hypothesis would be the presence of carbon-based molecules on meteors that strike the earth's surface.
Evidence of extraterrestrial livesAll biomolecules of life are carbon-based. Examples of these molecules include carbohydrates, proteins, ribonucleic acids, etc.
In order for life to exist in a place, carbon must be abundant.
Thus, the presence of carbon-based molecules on meteors from another planet that hit the surface of the earth may be evidence that life exists on another planet.
This can be used as evidence that life on earth came from extraterrestrial sources.

In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance
Answer:
Natural selection is a process that leads to evolution. For example variation can lead to this. Say back then one giraffe had a long neck this variation had a chance of being passed down to their children. If it keeps getting passed down by natural selection because its helping the giraffe survive then more and more giraffes will have long necks. Over time if the trait is super beneficial it could lead to the evolution of all giraffes having a long neck.
Explanation:
I used the terms that go with natural selection. If its not correct im sorry i tried lol.
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going on, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution affected their environment. Whiter moths were eaten by birds who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
