At noon the sun is directly overhead the sun rays fall vertically on the body so the shadow is very short.
So the rays fall vertically on the body. in mornings and evenings the rays fall at inclined position. So shadows are long at mornings or evenings.
Shadows are shortest at noon because the sun is directly overhead. So the rays fall vertically on the body. In the morning and in the evening, the rays fall at inclined position. So shadows are longer during morning and evening.
What are some of the ways that pollen can travel from one flower to another?
Answer:
pollinators + the wind
Explanation:
pollinators is probably the best answer here... pollinators are bugs like bees and butterflies that spread the pollen from one plant to another.
Answer:
Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.

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 !!!

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?

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.

Complete the table below about how each element is stored and cycled between living and non-living things.
10. Water
11. Carbon
12. Nitrogen
13. Phosphorus
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.

Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.
Research this issue, and summarize what’s known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
Answer: Yes.
Explanation: Because if it causes disease or problem then why continue to do it?
Answer: Well, from what my research is saying. cell phones emit low levels of non-ionizing radiation when in use. It can also referred to as radio frequency (RF) energy. And as stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. So, it has not been proven weather or not you could get a tumor or cancer from the energy waves.
Some information about a radio wave is that we can have an energy of around 4 x 10-10 eV.
Okay so, I do think people should limit their cell phone use for other reasons. For one, Phones can be overly addicting, I do speak from experience. Phones can also take up way to much of your time is you're just scrolling around on them.
Explanation: So at least that's what I would say. Hope this helped! :)
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.

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.
