Answer:
Prisims separate WHITE light, such as that form the sun, by wavelength.
Final answer:
Prisms disperse white light into a spectrum of colors through a process called dispersion, where light of different wavelengths is refracted by different amounts due to varying refractive indices. Instruments like spectrometers use prisms to separate and analyze these different wavelengths of light.
Explanation:
Prisms separate white light, such as that from the sun, by wavelength through a process called dispersion. Dispersion occurs because different frequencies of light have different refractive indices for a given material. When white light enters a prism—a piece of glass in the shape of a triangle with refracting surfaces—the path of the light is refracted (bent). However, not all colors are bent by the same amount; the bending of the beam depends on the wavelength of the light as well as the properties of the prism. Consequently, different wavelengths (or colors of light) are bent by different amounts and follow slightly different paths. The violet light is bent more than the red light, and, as such, when white light leaves the prism and is focused on a screen, the different colors line up side by side like a rainbow. This separation of colors is a key aspect of spectroscopy.
Additionally, instruments such as spectrometers are used to disperse light and form a spectrum for further analysis. In these devices, light enters through a small hole or narrow slit, is collimated by a lens into a parallel beam of rays, then passes through the prism. Different wavelengths leave the prism in different directions, and a second lens focuses these different images onto a detecting device, such as a CCD. This allows for careful examination of the spectrum created by the dispersion of light.

Which consequence of pollution is shown in the photograph?
A. Pollutants react with water and are deposited on Earth’s surface.
B. Eutrophication occurs in the presence of too many nutrients.
C. Pollutants break down the layer of ozone in the stratosphere.
D. Gaseous pollutants and particulate pollution form a haze over cities.
The consequence of pollution shown in the photograph is option D: Gaseous pollutants and particulate pollution form a haze over cities.
The photograph visually represents the presence of pollution in the form of a haze that hangs over urban areas. This haze is often caused by the emission of gaseous pollutants and particulate matter from various sources such as vehicles, factories, and power plants.
It is a visible manifestation of air pollution and can have detrimental effects on air quality, human health, and the environment.
The photograph shows that, due to pollution, gaseous pollutants and atmospheric pollution form fog over cities, as shown in option D.
What is the impact of this?
Lower incidence of solar rivers.Impairment of gas exchange.Increased respiratory problems.Extreme pollution causes polluting particles, less dense than air, to rise to the surface and combine with gaseous pollutant emissions, many from the burning of fossil fuels, remaining above the horizon, reducing visibility, and causing gas traps. inefficient, increasing the heat level and causing many respiratory problems.

tuberculosis
Please select the best answer from the choices provided.
A
B
C
D
Final answer:
Smallpox is the correct answer as it is not an endemic disease; it has been eradicated worldwide. Malaria, typhoid, and tuberculosis remain common endemic diseases in specific geographic areas.
Explanation:
All of the following are common endemic diseases, except smallpox. The correct answer is C. Smallpox.
Endemic diseases are those that are constantly present in a population within a particular geographic area. Malaria (A), typhoid (B), and tuberculosis (D) are all examples of endemic diseases. Malaria is often found in tropical climates and is transmitted by mosquitoes. Typhoid is a waterborne illness that remains a significant concern in areas with poor sanitation. Tuberculosis is a respiratory infection that is quite common in many parts of the world, particularly in urban areas with dense populations.
However, smallpox has been eradicated worldwide due to an effective global vaccination campaign. The last known natural case was in 1977, and it is no longer commonly found anywhere in the world, making smallpox the correct choice for the disease that is not endemic.

Heredity Lab Time to grab your virtual lab coat! In this lab, you will be investigating how hamsters inherit the traits for short or long fur. As you work through the lab, be sure to complete the Heredity Lab Report. You will submit your completed lab report for grading. Review the grading rubric before you begin.
Answer:
Hamster interit their traits based on their parents genes.
Explanation:
Hamsters do inherit their traits for long fur or short fur through the parents. The parents are what affects the offspring's traits, these are determined by the different genes. For example, if there is a recessive gene for short fur, then there will be less of a chance for the offspring to inherit short fur and vice versa. In some instances, there is a recessive gene and a dominant gene, in that case, the dominant gene will overpower the recessive gene hence it's name. There are three types of possible gene pairs, homozygous dominant: AA, homozygous recessive aa, and heterozygous dominant, Aa.If there is two of the recessive genes, then there is a higher chance for the short fur to appear in the offspring and etc.

Where are most of the nutrients from food absorbed? And what happens to the nutrients once they’re absorbed? (Worth 20 points)
Answer:
Nutrients get absorbed as the food is broken down, with the majority of nutrients being absorbed in the small intestine, where they're then transported into the blood stream
Explanation:
The majority of nutrients from food are absorbed in the small intestine after digestion. Nutrients enter the bloodstream or lymph system and are transported throughout the body. Undigested and unabsorbed materials are passed to the colon for water reabsorption and waste elimination.
Most of the nutrients from food are absorbed in the small intestine. The digestive system begins breaking down food in the mouth where enzymes in saliva start the process of digestion. This process continues as food moves to the stomach and then to the small intestine, where enzymes complete the digestion of food.
Once digestion is complete, the absorption of nutrients takes place. This is where substances pass into the bloodstream or lymph system, allowing them to circulate throughout the body. A substantial percentage, approximately 95%, of nutrient molecules are absorbed in the jejunum, the second part of the small intestine.
Other nutrients, such as iron and vitamin B12, are absorbed in different parts of the small intestine like the duodenum and ileum, respectively. Post-absorption, nutrient molecules are transported to various parts of the body for storage or further chemical modification.
Any undigested and unabsorbed matter moves into the colon (large intestine), where water is reabsorbed and the remaining waste material is eventually eliminated from the body through defecation.
Using the data from the graph, explain the relationship between the population of snowshoe hares and the population of the lynx. Explain what the graph's lines mean about the relationship.
As you already know, lynx are predators of hares and a balance between the populations of these two animals is necessary, so that the populations have a stable growth.
As you can see in the chart above, when the lynx population is very low, the hare population is high. This is because, as there are few lynxes, predation is low and hares are able to maintain their birth rate higher than the mortality rate. However, there are many hares available for lynx to feed on, which allows the lynx's birth rate to also be higher than the mortality rate, which causes the lynx population to grow.
Also according to the graph, you can see that as the lynx population grows, the hare population decreases. This is because the greater number of lynx causes predatorism to increase and hares are hunted by lynx in greater quantities. This causes the mortality rate of hares to be higher than the birth rate, which decreases its population. On the other hand, the abundance of food allows the lynx population to grow to some extent. This is because, as you can see in the graph, when the hares population is very small, the lynx does not have enough food, which causes an increase in the mortality rate, also decreasing the lynx population.
When the lynx population is low, predatorism is lower, which allows hares to reproduce by increasing their population, which will result in an increase in the lynx population.
The graph shows how the population of snowshoe hares and lynx are related over time. When hare population is high, lynx population increases, and when hare population decreases, lynx population decreases.
Explanation:The graph shows the relationship between the population of snowshoe hares and the population of lynx over a period of time. The x-axis represents time, while the y-axis represents the population size. The lines on the graph indicate the trends in the population sizes of both species. When the snowshoe hare population is high, the lynx population tends to increase, as lynx feed primarily on hares. However, when the hare population decreases, the lynx population also decreases due to a lack of food.
