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).

Draw a flowchart to show how food becomes energy that cells can use. Make as many steps as needed. The entire process needs to be clear to someone who’s learning for the first time about the energy that humans use.
Answer:
this is the answer from edmentum
Explanation:
The main reason that people eat is to get energy and the energy is used by the body to carry out its daily activities.
It should be noted that when we eat, the food needs to be broken down in order for the body to use them. This is done through the process of cellular respiration.
The energy that is in the food that's consumed by human beings is changed into the energy that's usable by the body cells. For example, the sugars in the foods will be digested into a monosaccharide. Also, the energy that's stored in the glucose is converted to ATP which is vital for the body.

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.
