Graph (see next page for graph paper grid)
Using the data from the Coal Production Table, create a graph of coal usage in each region over
the years. The x-exis should be years, and the y-axis should be coal production. Use a different
symbol or color to represent each region. Remember to include titles and labels.
Scan or take a picture of your graph and submit it with your assignment
.
Analysis
Changes over time are called trends. You can see on the graph a downward trend in the
Appalachian and Interior regions and an upward trend in the Western region.
Try predicting future coal production. Using a ruler, draw the lines for each region. Go beyond
2011. Draw the line with the same pattern it follows on the graph. The extension of the lines is
based on what you predict will happen with coal production.

Questions
1. How much coal will be produced in the year 2020 for each region?
2. What trend would you predict for the next ten years for each region?
.
3. If people keep using coal in the same way, scientists say there may be enough coal reserves
to last 200 to 300 years. Does your graph show trends that match what scientists say? What
kinds of factors might cause them not to match?
4. Can you think of any problems that could come from using only 15 years of data to predict
trends for the next 100 years? Explain your answer. How could you prevent some of these
problems?
Answer:
Try this.
Explanation:
I'm not too sure because the teacher never gave me enough information (Need Bigger Graph). Get bigger graph paper as it says "The X-axis should be years and the Y-axis should be coal production." On the X-axis (Horizontal Line) write "Years" and on the Y-Axis (Vertical Line) write "Coal Production."
Now, your gonna start listing all the years on the X-Axis 1996 through 2011, And on the Y-Axis list all the coal productions 145 and all the numbers through 634. Make sure you have the regions, Appalachian, Interior and Western.
I'm sorry if this didn't help, this is what I did and it helped me, I thought it might help you too.

4. Genetic Equilibrium...explain it.
Answer: Genetic equilibrium is a situation where allele frequencies in a gene pool are not changing. In other words, the population is not evolving. The conditions to maintain the genetic equilibrium are no mutation, no gene flow, large population size, random mating, and no natural selection. The equilibrium can be disrupted by deviations from any of its five main underlying conditions.
An example of this in humans would be a heterozygote for brown eye color. The person would carry both a dominant brown allele “A” and a recessive blue allele “a” yet have brown eyes. The dominant brown allele masks the recessive blue allele. Genetic equilibrium is the state in which allele frequencies remain constant.

Use the terms on the right to complete the sentence. Starting with a diploid parent cell containing 32 chromosomes, determine what mitosis and meiosis would yield. NOTE: Some terms may be used twice, or not at all. Incorrect answers will cancel out correct answers. 16 chromosomes 2 haploid cells 2 diploid cells 8 chromosomes 4 haploid cells 32 chromosomes 4 diploid cells Mitosis would yield _____ cells with _____ chromosomes in each daughter cell. (2 options, 1 point each) Meiosis would yield _____ cells with _____ chromosomes in each daughter cell. (2 options, 1 point each)
Answer:
Mitosis would yield _2 diploid_ cells with __32__ chromosomes in each daughter cell. Meiosis would yield _4 haploid_ cells with _16_ chromosomes in each daughter cell.Explanation:
There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis, they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.
Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation.
Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.
• Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of the chromosomes of the original one.
• Mitosis produces two daughter diploid cells (2n) from a diploid somatic cell (2n). During mitosis, the whole-cell first duplicates and then separates.

In what ways can the
environment impact the traits of an organism?
Answer:
Heyaa!! My name is Pinky and i'm here to inform you that your answer is...
Explanation:
!!! an organism will adapt to survive an environment. For example if an environment is very cold the organism will develop a thicker coat to trap in heat. Another example is if it is an environment with many trees, an organism might develop claws to climb trees or a tail to assist with balance and climbing !!!
Have a nice dayy!!
~Pinky~
Answer: Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal's genes are expressed, which ultimately affects the animal's phenotype. Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions. include temperature, food, pollutants, population density, sound, light, and parasites. brainliest?
Explanation:
bicycle tyres become flat when the weather is cold.Why?
Answer:
The tires lose air pressure in the winter because it contracts. If you have 35 lbs in the summer, with 85 degrees, when it gets cold, down to -10, your air pressure can get down to about 25 lbs. So before it gets bitter cold, inflate your tires up a little. You don’t want to be putting air in your tires once it is freezing out. Sometimes the schrader valve doesn’t seat properly because of frost and the rubber seal is hard. I have had several tires go flat on me because of this.

Give 4 ""combining evidence"" in favor of organic evolution.
Answer:
1. Fossil record
2. Comparative anatomy
3. Embryology
4. Biogeography
Explanation:
Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:
1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.
2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.
3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.
4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before the separation of the continents are often distributed worldwide.

Why do you think the winter layers are darker than the summer layers in the ice core?
Screen shot is included
Answer:
Why do you think the winter layers are darker than the summer layers in the ice core? The winter layers are darker than the summer layers because little snow falls in the winter. ... The summer layers are lighter because the snow that falls in the summer is cleaner; there are fewer particles caught in the snowfalls.
Explanation:
You can put it in your own words if you want. Hope this helps!
The winter layers are darker than the summer layers in the ice core because the summer snow is less tightly packed with particulate matter, therefore, it is brighter while the winter snow is more tightly packed due to the compaction and therefore it is darker.
What do you mean by Ice core?Ice core may be defined as a structure of ice in a cylindrical shape which are plugged from the ice sheets or glaciers.
In winter, the snow that falls on the earth's surface is mixed with the more particulate matter due to compaction and hence it looks more darker as compared to summer snow.
Therefore, it is well described above.

Where is it stored?
How does it get into animals?
How does it get into plants?
How does it get recycled again?
Answer:
13
Explanation:
it get recycled again when it becomes old
Phosphorus is stored and cycled between living and non-living things.
What is non living things?In biology, anything devoid of life, such as an inanimate item or body, is referred to as a non-living thing. A non-living creature lacks the traits that define a living thing as compared to the one that has life.
A non-living entity, for instance, lacks the essential component of life, a living cell that develops, metabolizes, reacts to environmental cues, reproduces, and adapts.
There are two representations of inanimate objects. On the one hand, a non-living thing refers to an object that once had life but has since passed away. A non-living thing, on the other hand, is one that never had life and never will have life.
Therefore, Phosphorus is stored and cycled between living and non-living things.

undergo total internal reflection.
refract towards the normal.
have an angle of incidence smaller than the angle of refraction.
Answer:
refract towards the normal.
Explanation:
Refraction refers to the bending of light waves or change in the direction of light waves as a result of change in the speed of light at the boundary between two media.
Whether the rays bend towards or away from the normal depends on the density of the both media. When light travels from medium 1 to medium 2 and medium 1 is less dense than medium 2(shown by a greater speed of light in medium 1 than medium 2) then the ray of light refract towards the normal and vice versa.
