Refer to the graphs below. Determine the type of forest these moths inhabit. Use evidence from the Peppered Moth simulation and the graphs as well as scientific reasoning to support your response.
Answer:
They live in a forest that has trees with dark colored bark.
Explanation:
Because the dark colored moths can blend in better with dark bark than light colored moths do, they don't stand out as much, so the predators(the birds) will eat the ones that they can find easier, which happens to be the light colored moths.

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building
Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Explanation:
The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.
The steps involved in the rock cycle are:
Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface. After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water. The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks. Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.
Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.

Carbon dioxide (CO2) keeps INFRARED light from leaving the Earth. *
True
False
Answer:
I believe it is true.
Here some info to back it up
Carbon dioxide (CO2) is also an important greenhouse gas. It has a long lifetime in Earth's atmosphere. Carbon dioxide strongly absorbs energy with a wavelength of 15 μm (micrometers). This makes carbon dioxide a good absorber of wavelengths falling in the infrared radiation region of the spectrum.

What are genetics? (short definition)
Answer:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins
Answer:
Genetic is what traits are passed down from a mother and father to their child. Eye color, height, and hair color are some examples of the traits that are controlled by genes. Genes exist inside the cells that make up living things

The carbon dioxide from fossil fuels acts is the same as the carbon dioxide that we breath out... Why does burning fossil fuels cause global warming if breathing doesn't?
The carbon in fossil fuels is very very old. The carbon that we breath out is much newer.
The carbon in fossil fuels was unable to reach the atmosphere until humans dug it up. The carbon we breath out was already moving around on the surface.
Plants don't like to absorb the carbon that comes from fossil fuels. However, plants love to use the carbon that we breath out.
For some reason the carbon from fossil fuels is stronger than the carbon that we breath out.
Answer:
When we breathe out CO2 There are a lot of plants to take carbon dioxide away, but due to the cutting down of forests there are fewer trees to absorb CO2 and more burning of fossil fuels is causing CO2 levels in the atmosphere to increase
PLS MARK ME AS BRAINLIEST
Explanation:
Answer:yes
Explanation:because the fossil fuel is much stronger than the carbondioxide we breath out e.g the fossil fuel that comes out of factories are much so it can easily cause global warming than that of the carbon dioxide we breath out
