Explanation:
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
whoever answers first gets brainliest
Answer:
The light colored pepper moths were able to camouflage in the Birchwood trees unlike the darker ones. But when the industrial revolution came the amount of smoke from the factories made the Birchwood trees become darker in color do now the darker pepper moths were the ones who could camouflage while the white ones were easily eaten and killed. Since the darker colored moths were able to survive they had offspring who were also darker colored. Over time since mainly darker moths were produced it was common for pepper moths to be darker.
Explain how science uses fossil evidence to support the theory of evolution
Answer:
The fossil record
Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
The theory of Evolution is supported by the evidence given by fossil study. Fossils are the preserved remains which helps us to know more about the past times.
What is the Theory of Evolution?
The theory of Evolution explains that the environmental changes lead to the gradual change in traits which enhance the survival of organisms in environment. This explains natural selection. This theory has been proposed by Charles Darwin.
Fossils provide evidence about the organisms from the past that are not the same as those found today. Fossils are the preserved remains or traces of organisms which are important evidence of evolution.
Fossils show a progression of evolution. Scientists determine the age of fossils through radioactive decay which helps in categorize them from all over the world to determine when the organisms lived.

explain the science behind the ozone layer and why its thinning is a concern.
Answer:
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity.

What kinds of matter are likely found in this system?
Answer:
Even though matter can be found all over the Universe, you will only find it in a few forms Scientists will probably discover more states of matter as we continue to It's a fun state of matter when you remove almost all energy from a system.
Explanation:
The matter can be observed all over the Universe present in a few forms in the system. Scientists discover more states of matter.
What is system ?The part of the universe in a thermodynamic consideration is called a system and the remaining portion of the universe is called surroundings.
Universe can be a combination of system + surroundings
A system is called as open system where exchange of both matter and energy with their surroundings, If water is kept in an open vessel it is allowed to exchange of matter and energy.
Closed system is defined as the exchange of energy with the surroundings, like if some water is placed in a closed metallic vessel, so no exchange of matter occur between the system and the surrounding can take place.
Isolated system is defined as the system where neither matter exchanged nor energy with the surroundings; Homogeneous and Heterogeneous systems refers to any system which consist of a single phase is called Homogeneous and if any system has more than one phase is called Heterogeneous.

Which organelle found in plant cells allows them to make food using sunlight? lysosome chloroplast Golgi body nucleus
Answer:
Chloroplasts are organelles that are filled with a green substance known as Chlorophyll. Chloroplasts are what convert water and sunlight into sugar/food, in a process known as photosynthesis. Plants can't hunt or gather food, so they make their own through chloroplast's. The Mitochondria are the powerhouses of cells.
