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.

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.

A. All living things are made of cells.
B. Cells are the basic unit of structure and function in all living things.
C. New cells are produced from existing cells.
D. All cells have all the same structural parts.
Answer:
C. New cells are produced from existing cells.
Explanation:
Has three tenets:
1. All living organisms are composed of one or more cells
2. The cell is the basic unit of structure and organization in organisms
3. Cells arise from pre-existing cells
*C. is not one of them*
D. All cells have all the same structural parts is NOT a tenet of the cell theory.
The Cell Theory gives a description of what cells are. There are basically some set of principles that give a concise idea of what cells are. These set of principles are regarded as tenets of the cell theory.
Three major scientists named: Rudolf Virchow, Theodor Schwann, and Matthias Jakob Schleiden are credited to have postulated the tenets of the cell theory.
The major tents of the cell theory include the following:Every living thing on earth are composed of cellsThe functional and structural unit of all living things are cellsThrough the process of division, new cells are formed from old cellsThe chemical composition of all cells are the sameNote: All cells however do not have the same structural parts.
Therefore, option D. All cells have all the same structural parts, is NOT a tenet of the cell theory.

A. DNA
B. Genes
C. Chromosomes
D. Nucleus
A stretch of DNA with instructions for one trait is called as Genes. So, the correct option is (B).
What are Genes?Genes are the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after another at specific locations on chromosomes in the nucleus of cells.
A gene is described as the basic physical and functional unit of heredity that is made up of DNA. Some genes serve as instructions for making molecules called proteins, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to over 2 million bases.
Genes carry the hereditary information from one generation to the next which control the structure and metabolism of the body.
Thus, a stretch of DNA with instructions for one trait is called as Genes. So, the correct option is (B).

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.
