Answer:
I believe the answer is A: Neveah's mass would stay the same but her weight would decrease
Explanation:
I believe its A because the moon has about 1/6 as much gravity as the Earth. So if anything, her weight would decrease, not increase like B., C., or D says. I hope this is helpful to anyone who reads it!!! ;)
Answer:
Greenhouse gases absorb radiation from the EARTH and reradiate back toward the EARTHwhich help to maintain a normal temperature range in the Earth.
Explanation:
Greenhouse gases are gases that are capable to of absorbing infrared radiations that are emitted from the Earth's surface and reradiating back to the Earth which contributed to the greenhouse effects. Examples of greenhouse gases are carbondioxide, methane and water vapour. Others are ozones, flourinated gases, nitrous oxides e.t.c.
The green house gases has lead to climate changes in the Earth by trapping heat, the contribute to respiratory diseases by smog and air pollution. Greenhouse gases concentrations are high during warm seasons and low during cold seasons.
1. Natural selection is the best of the organisms to live past hardships and survive, leaving the weakest to die. Survival of the fittest.
2. Adaptation is an organism changing to better themselves in a certain environment.
3. These moths were adapted to blend into their surroundings, so as to not be seen by predators.
4. Because of the pollution from the city, the tree’s bark turned from a lighter shade brown to a darker shade brown.
5. A majority of the moths were a lighter gray. With the changing color bark they were seen more by predators.
6. Adaption caused the first darker moths to appear because they learned they needed to blend into the new tree bark color.
7. The change from light to dark gray was very needed for moths. It explains natural selection for those moths who did not adapt to different color gray. Adapting the new tree bark color helped moths been less seen by predators therefor keeping their species more alive.
