answer:
stars create new elements in their cores by squeezing elements together in a process called nuclear fusion
explanation:
stars are made of very hot gasthis gas is mostly hydrogen and helium, which are the two lightest elements stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements1. Give an example of a behavior you observed in another person. When you looked at
their behavior, did you decide their action was more a result of circumstances, or their
personality? What information did you use to make your judgment? (6 points)
(its psychology btw)
Answer and Explanation:
The person to whom I observed a behavior that will be exposed in this response was a character from a show called "Reply 1988." This character showed a highly explosive behavior and was very nervous and stressed. I believe that this behavior is a result of the circumstances that this character was experiencing at the time, as he was under a state of great tension and stress, as he believed that his son had suffered a plane crash. In addition, this character has always shown a very calm and peaceful personality throughout his life, which shows that the explosive behavior was caused by the circumstances. To make this judgment I used the way the character behaves in his daily life and his interactions with other characters.

Explanation:
Light absorbing compounds, whether they are found on a painter's brush or in a living cell are known as
Answer:
Pigments
Explanation:
The term pigment derives from the Latin pigmentum, which means "substance that produces color".
Pigments provide color to cells and tissues.
In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem color, flower color, and other tissue colors are defined by pigments on their cells.
Animal cells also have pigments that provide color to tissues like the hair, the skin, or the eyes.
Pigments are, basically, chemical molecules that produce color by the selective absorption of sunlight. They absorb light of certain wavelengths and reflect other wavelengths. The color expressed is the product of the reflection.
Many pigments have other functions, such as catalyze for some reactions. They accelerate or facilitate chemical reactions.
Pigments can be differentiated into two groups:
The ones with nitrogen in their molecules, such as hemoglobin, chlorophyll, biliary pigments, and melanin. The ones with no nitrogen, such as carotenoids and flavonoids.
Mendel's experiments demonstrated the law of dominance: traits are inherited as dominant and recessive alleles, and the dominant allele for a trait can mask the presence of the recessive allele. Occasionally, that law is contradicted: offspring exhibit a blend of their parents' traits. For example a red flowering plant when crossed with a white flowering plant would produce a plant with pink flowers. This type of inheritance pattern is called A) codominance. B) multiple alleles. C) incomplete dominance. Eliminate D) heterozygous dominance.
Answer:
Incomplete dominance

5. How is the heart (circulatory system of a frog different from a human heart?
Answer:
The circulatory system of a human compared to that of a frog is different due to the number of chambers. A frog’s heart has three chambers (two atria, and a single ventricle), whereas a human’s has four (two atria, and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin.

In a forest, gazelles were the main source of food for cheetahs. The gazelles depended on grasses and shrubs for their food. A mysterious disease quickly spread among the cheetahs, killing many of them. What impact would the decline of the cheetah population have on resource availability?
Because the number of cheetahs declined, the population of gazelles will most likely . This situation, in turn, will lead to increased between the gazelles and other herbivorous animals that eat the same food as gazelles.
Answer:
due to natural selection , if the predator of the gazelle declines, then the prey the gazelles will increase since there isn't many cheetahs killing them anymore.
the second should be competition, since there will be more gazelles needing to eat.
Explanation:
How do photosynthesis and respiration work together to produce energy to support
life? How are the processes similar? How do the processes complement each other?
Photosynthesis and respiration work together by creating the energy and transporting it.
The process are similar because they both take something in, and let something else out.
The processes complement eachother by Respiration being able to take oxygen to the leaves, and the leaves using that oxygen to power their chemical reaction.
Good luck there friend!

A local citizen science group is monitoring the water quality of a nearby lake. They gather water
samples once a week on Wednesday between the hours of 7 A.M. and 9 A.M. from the same location.
One day in August they were unable to sample within that time frame and collected the sample at
3 P.M.
How might this modification to the sampling procedure affect the results?
Answer:
Greatly affect.
Explanation:
This modification to the sampling procedure greatly affect the results because timing of sampling is very important that can change the results of an experiment. The water quality of lake is different in different times of the day due to human activities. The quality of water is good in the morning when there are no or less activities of people as compared to afternoon when the human activities are very high so timing can greatly affect results of the experiment.

European Jewish Immigration
What was life like for European Jewish immigrants in the United States?
due today please help
Shortened version (if needed):
Many European Jews immigrated to the United States throughout the 19th century for better life and more opportunity. They soon found life in the American economy, and their culture rose to prominence in the U.S. through their religiosity, their work, and their social customs. However, many Jewish immigrants faced difficulty throughout the 20th century during the Holocaust and immigration restrictions. Despite this, many Jewish communities in the U.S. continue to remain prominent to this day within states along the East Coast.
Answer:
Affected by economic hardship, persecution from European governments, and many other social upheavals that occurred throughout the 19th century, many European Jews immigrated to the United States for better life and more opportunity. Many of these immigrants settled in American cities such as New York City, Philadelphia, Baltimore, and dozens more cities across the United States, primarily along the East Coast.
Many of these Jewish immigrants found work in the garment industry and started their own businesses. Though many Jewish immigrants came to the United States with little money, they quickly found life within the American economy mostly as workers, peddlers, and unskilled laborers. Their culture rose to prominence in the United States throughout the 19th and 20th centuries through their religiosity, their social network, their work, and their social customs.
However, by the 1920s, anti-immigration sentiment was growing, and a law was passed by the U.S. government known as the Immigration Act of 1924, which severely restricted immigration from many European countries, and as a result, it disrupted Jewish immigration from Europe. Although the law was repealed in 1965, the rate of Jewish immigration in the United States never topped rates before the 1920s ever again. Many Jewish immigrants opposed these immigration restrictions, especially as World War II started, and what became known as the Holocaust paved way for the persecution and death of many Jewish families in Europe. Many Jews in Europe continued to find ways to enter the United States during and after World War II, and to this day, many Jewish communities in the United States remain prominent in many states along the East Coast, especially in New York.
